Good to see it un-blow’d up brother💪

I am the least mechanically inclined out of my three brothers. You have taught me more than they have in the few months I've subscribed to your channel. Thank you bro!

That's an ignition issue. I've had 5 blasters in my time, that's not a fuel issue. The stock pipe was great, the stock carb was perfect, and they actually ran REALLY well once you deleted the fuel/oil mixer. That one is losing spark under load or the ports are so bad on the cylinder it's cutting out under extreme load. I still say it's coil/wire/plug issue. Those bikes are AMAZING for their size and with a little work they can make really good power. You're making me want another one..

Could be the cheap coil breaking down after warm up and higher revs

I need more junkyard digs right now man. You are the absolute greatest!!!!!

First 2 stroke quad was a Polaris 250 TrailBoss. Lots of great memories with that machine including burning hundreds of gallons of dads gas and as much cheap TCW-3 as he would keep on the shelf lol. Now 20+ years later I’m that dad buying my son a 250 TrailBlazer, blowing it up from a failed oil pump and learning how to rebuild it. Genuine Chinesium piston to the rescue!

Can not wait to see you and PBG hang out again. Those videos are amazing.

Definitely go through the ignition system. Timing is everything on a 2-stroke, plus any Chinese parts probably won't give a decent spark. Failing that, double check for air leaks and reed valve sealing (fiber reeds are good with an after-market exhaust)

You should really do these smaller type engine rebuilds! super fun to watch. keep up the great work man.

Seeing your troubleshooting process, even without regard to the specific engine/vehicle (though that's awesome in its own way for anyone who has the same issue) is invaluable because the viewer learns how to attack a problem and solve it systematically. It's so easy to get overwhelmed and say "f**k it!! - these videos help cut through that noise and static of frustration. Much appreciated, SPC Brown!

I respect the right to privacy and would never come to your shop but do you and Mook ever do any local meet and greets like octemberfest...big fan of your content and have fun watching older videos as we all wait for your new content. Keep it up Kevin you have made it entertaining and very informative. Ty

I love the variety of content.. do more small engines please.. You are always great to watch.

Good to hear that the Bonneville is getting the business, its going to be awesome. Also this small engine content is always a great change of pace. I always wanted a Banshee, Raptor, or a Blaster unfortunately it just wasn't in the cards.

I liked your revival, it shows you what can be done with just a few tools. Also, your experience pays off as well. Hey, it's wheels, you can't beat that.

Before the snow flies you should do a fleet update video, ride around the yard and the shop and tell us what's around.

One thing I suggest is you get one of the cheap central pneumatic air chisels from harbor freight for when you're using a Shake N Break, the knob on the bottom for adjusting the power of the chisel is usually pretty annoying, but for a Shake N Break it's really nice for being able to set your max power and go. The air chisels that have the variable trigger (at least in my opinion) aren't as good for it.

i really liked the 2 stroke street bike you did and the snowmobile stuff so if you randomly inject videos like this into your schedule i'll probably watch them. this market isn't anywhere near as saturated as the car revivals and a lot more achievable at home by the diy guy from a financial standpoint. i'm also really enjoying your (from a long time viewer) newfound appreciation for old gm land barges. edit: can't spell

Those hand impact screwdrivers are awesome for getting the phillips screws out of brake discs

Man, a 99 Blaster was my first ATV. $500 in like 2015 got me a 99 Blaster, with a title. I knew nothing when I bought it, but as I came to learn it was a fully built race bike. Big bore kit, bigger carb jetted amazingly, full exhaust kit, full race plastics, etc. if there was a performance part made for a blaster, this thing had it. Ran amazing too, my 230lbs fatass could pin it while cruising in 4th gear and it would pull the front wheels up. I raced a friend who had a new Raptor 700 and we were neck and neck. Good times, good times.

Again it’s the best when junkyard digs posts 😊

Another great video. The sound of a 2-stroke reminds me of a 1975 Kawasaki 400 two- stroke triple that I used to own equipped with chambers. From idle up to around 2500rpm it was sort of doggie. Then between 2500rpm and 3500rpm it would kinda wake up. From 3500rpm to the red line that bike turned into a rocket. What I really remember was the change in the exhaust tone as it went up the rpm range. It went from popping corn to an angry shriek. A well tuned 2-stroke with an expansion chamber is music to my ears.🏍

Blaster top-end ting could be a whole new percussive element in a sample kit for budding producers

My family purchased a Yamaha Timberwolf brand new in 1999, it is absolutely the highest quality mechanical item I have ever had the pleasure to work on. Every screw, every piece of hardware, just feels like quality and fits perfectly. The only serious issue has been a very warn out Mikuni carburetor.

I had one as a kid. Blew it up and learned how to rebuild it myself. Good times 🍻

Always happy to see a junkyard digs vid to come out

@41:58 "Ernest Goes to Camp" (1987) When Ernest's golf cart starts moving on its own and it shows up periodically throughout the film driving by its self.

Correction, att. New viewers , there is no normal content on this channel. Lol. Actually, JYD. Is a well-educated and talented mechanic with a wicked sense of humor. Hang on and watch. Central California watching

Its always a good day when JD uploads

Back in the 1980s I used to work as a motorcycle electrician and if I remember correctly, those bikes have a CDI ignition system with a separate high voltage ignition winding in the alternator that charges a capacitor, that's then discharged into the ignition coil. Quite often ignition problems like those your having are caused by a bad alternator stator winding where the insulation is starting to break down at high rpm. However as you say the ignition coil has been replaced with some sort of after market part, I would try changing that first as if it's not the correct type meant for a CDI system, that would also cause problems. Also the ignition coil is a lot easier and cheaper to swap out than the stator winding. Good luck with fixing it as it looks like a fun bike.

So far I’ve been watching you for a month and so far I haven’t seen you fix anything right. Anyone can make things run but it takes a real mechanic to do it correctly.

Hey Kevin, you should fix that purple Ranger you drove in highschool out of some junk or something. I think it'd be neat for a nostalgia trip of some sort from you.

Those blasters are a blast to ride. Love your content!

I have 2 blaster just like yours. One just rebuilt, the other waiting on parts. Finicky yes, but fun as hell to ride once you get it right. pt 2 on this thing would be sweet.

I was thinking: I need to go watch a four wheeler revival and as soon as I opened my laptop, I see that junkyard digs has posted another banger so of course, I click on it. Keep up the good work Kevin

Worked at the local Honda dealer right after graduating high school. Had a lot of two strokes come in that had been brought in that had been pretty butchered by people who thought they knew what they were doing. On several occasions the bike or wheelers had been gotten to run after several years of sitting somewhere. 9 times out of 10 the seals in the crankcase had dried up and crumbled leading to a vacuum leak at the crank seal. Usually not a big deal at lower rpm but when the engine gets up on the pipe that lean condition burns the top out of the piston. If the piston top isn’t burned out first the rings are the other culprit for a top end coming apart. The extreme heat from running lean kills ring tension as well as the lean condition causing scoring in the cylinder from lack of lubrication ( lean condition on two strokes also means less oil mix from the fuel to lubricate everything ). Another common problem was with ignition, people would grab any plug that would thread in the head without hitting the dome of the piston. Commonly they had grabbed an automotive plug for a newer vehicle which are resistor type spark plugs so that they don’t cause interference with cars computer systems or static in the radio, great for a car but not a high rpm bike engine. Get yourself a good plug boot and correct spark plug to begin with. Check the air gap between your flywheel and the stator as well, also another source of weak ignition. You’re absolutely right about the junk Chinese coils as well. After that, start checking grounding and continuity in the wiring. Probably not much help to you here Kevin but maybe it was worth it to give you an idea of another place to look for the problem. Good luck with it and great video again, glad to see it.

Just as I'm about to go to bed I see a Junkyard Digs notification 😂.

Love it good to see things get a new life

Back in the "day" I used to be able to buy a wiseco piston, ring set, and rod for 100-150 bucks. I was buying blown up blasters out of the newspaper for under 500 bucks. Rebuild them, clean em up, and flip them for 1000-1200. I also did other 4 wheelers that usually needed minor repairs. I did this until I had enough cash to go buy a brand new 400EX in 2001.

I love waking up to a junkyard digs video.....keep doing what ya doing brother. Much love from the uk 🇬🇧

thanks for uploading another great video! Keep up the awesome job guys!

Love you all I am a big fan of the channel I love your sense of humor and the van™ can't wait for next weeks vid.

the first thing I think of when I heard you say you are going to Minnesota is "Kevin, Dalton, and maybe Angus... oh that's gonna be good :) "

Oh god... The Right Stuff on the case halves!!!! Getting that thing back apart to fix that sloppy clutch is going to be FUN!!!. Really need a tube of Yamabond5 for those cases (and you'll fall in love with it for car stuff too). Along with Yamabond4 for the 'normal' stuff. Also, speaking as an ex-Yamaha service manager, you might have figured out on Blasters, be VERY VERY carefull putting the screw-on top of the carb. They're easy to crossthread, then leak air afterwards. That alone is the main reason I had to rebuild blown up Blasters back in the day. Sucks raw air and melts the piston. Second only to the guys that would jet spray the engine and blow the base gasket into the crankcase. Oh, and if you ever decide to build it right, don't go with Wiseco. Get a factory Yamaha cast piston and rings. On those engines, the stock 'junk' just flat out works better.

I always enjoy your videos they are very educational and I am impressed at how easy it was to get the 4 wheeler to run. I can always learn new things

Love your content! Keep up the great work!

What a great episode. You're my favorite car channel. I'd love to learn how you became such a good mechanic. It's nice to see someone who doesn't cut corners for likes. Please tell me that Mustang II outside the shop is in the future. Keep up the excellent content!

yalls kitchen with all the oak is absolutely adorable!

Kevin another completed project. 2 strokes are hard to get right. But, it’s not bad either. Thank you for sharing! 💯👍👊

Interesting to learn that your first vehicle revival was a second gen Ranger. So was mine. 1997 Single cab Flare side 2.3L 5 speed. Love those little trucks.

Rule of thumb on a two stroke, if more than two turns out from a light seat on the air screw, the pilot jet is too rich…also run the risk of the air screw falling out 😅. Less that one turn out from light seat, Pilot is too lean. Four strokes are backwards since you adjust fuel delivery and not air Lower or raise the needle clip one notch to clean up the center range

Cut out under load usually means coil fault. Fun video to watch. Haven't played on 2 stroke stuff in quite some time.

Kevin, did I miss something or @36:43 when you put the seat back on after cleaning the filter, you forgot to put the filter back on?

I love the videos, I wish you could put out more, keep up the great work!!!!

if a 2-stroke has fast speed problems, turn the high mix up until it intermittently 4-strokes. The richer mix and extra stroke will help lube the cylinder and cool the combustion chamber.

Some of the old bikes had a pre filter in the petcock that clogs up like a champ. 👍

If it’s Still cutting out you should check the packing in the silencer if it was running rich before the engine blew it could be clogged up restricting the exhaust flow

Proper coil, new plug and plug wire will most likely fix it.

Another great video, would love to see you explain the carbs. You are great at explaining that kind of stuff in detail and making it understandable.

the clutch basket is toast. All those grooves are the reason why they were stuck.

The air filter being greasy is probably air filter oil spray on to help catch smaller dust n crap but if your riding with others n your n the back of the pack u & the air filter r going to catch a lot of dust

I’d replace the crank seals. Will cause weird lean issues. A failing stator can definitely cause your issues too

I would love more revivals on 90,s cars as those are more available in my area. Would love to learn more. Hard for me to find a channel about working on cars that isn’t dry and boring.

Gotta love when your looking. For somthing to watch and get the notification junkyard digs post

I think you should check the crank seals.

Looks like I’m not sleeping for 40 minutes

Thanks for the change up on content. Makes me me want to fix a YFZ450 that I lean locked in the shop about 10 years ago.

Is there a new snow mobile challenge this year by chance. I really enjoyed watching that and you are the grand marshal when keeping the challenge going strong.

I have to say I have watched almost all your videos. I've been watching you since you first started posting them... and it was nice to see you do a quad... keep the great content coming and Have a great weekend!!

11:09 this is s very good example/explanation of how a clutch works i kinda undestood but anything i didint u cleared up thx for that

Cool to finally see some quad content, race quad or bike next?

Good job, and cool of you to offer it back to the guy. Really interested in seeing how to do small engine tuning done properly. I can usually get there in the end, but I'm moslt guessing! If you can do it using the Keihin carbs found on little Hondas (like the ones you showed when you did the voiceover) that would be awesome too! Thanks!

Love to see another old Sled Challenge this winter.

That little device on top of the carb is called a TORS (throttle over ride system) it controls your throttle separately of your cable from the thumb throttle. Disconnect it, or delete it all together. When it finds throttle signal at wide open for a certain time, it drops power down by lowering throttle. That's why it feels boggy on top

This was a super-satisfying rehab. Thank you!

I always run 40-1 no matter what the engine calls for. It's never ruined an engine and It has never failed me. Too much oil can bog the engine!

That 80 you were talking about probably has a wiseco pro-lite piston in it. Those pistons get hot fast, faster than the cylinder sleeve so if you dont let it warm up for a while it expands and locks itself up in the sleeve. Thats what it sounds like to me is your problem. People that dont know much about them usually buy them not knowing its a process to get it to work right and then wonder why it locks up so much. I rode 2 strokes for a while and i stayed away from the pro-lite, i got the wiseco woodsport or something. Its a little heavier to keep momentum for low end grunt.

I hope you can eventually have a blast with the blaster

I saw my favorite car in the background near the end. The salvaged Mustang II. Please tell me it will be making a comeback because it deserves it. And may be get John motivated to help get his Mustang working as well. A two Mustang video on both channels would remind me of bad things but give me hope that those things can indeed be fixed. Please make this happen!!!

I used to race Blasters cross country in hare scramble races. I raced the Missouri Hare Scrambles Series Championship. I of course ran the 200cc class where everyone was on a Blaster. I actually won the series championship in the year 2000. I knew all the tricks to get those Blasters running like a champ. I can't believe you would run that new top end for even one second without a clean air filter on it. I still think you have carb issues. My guess is it needs an even bigger main jet. Just my two cents. I also only ran genuine Yamaha parts. I never put any crap made in China on my bikes or quads.

I need more junkyard digs right now man. You are the absolute greatest

I had an '89 Yamaha Blaster in the early 90s. It was a fun rig, but it wasn't exactly blindingly fast as my cousin could effortlessly pass me on his Honda 250R quad in 2nd gear (so he CLAIMED) while I was maxed out on the Blaster. Maintenance? Had to change out the fouled plug every so often and NGKs weren't cheap back then either...

if this becomes a series, please do a 30 over bore out, it makes them soooooo much better.

Junkyard digs is the best. Are you thinking of fully restoring any of your cars?

Huge congrats on 1 million subscriber 🎉🎉🎉

Getting flashbacks to 1984 and my Motoski Futura 440 and the piston skirts grenading at 70 mph down mainstreet Moosonee. That was the most critical damage my 16 year old eyes had ever seen.

Junkyard digs and pole barn garage = fucking good time

2 stroke gassers: "the barometric pressure is too low and your vibe is wrong I'm not starting" 2 stroke diesels: *running on water, engine oil and 30 year old gas*

I had a 200 Blaster as a teenager, I jumped the shit out of that thing. It was so much fun!

Ive got that same top end kit in my blaster. The main failure is the wrist pin needle bearing. If you can get a oem/high end bearing they run good. Mines on 30+ hours already and it was rebuilt 3 weeks ago. I beat the piss out of it. Run it richer then you would a oem cylinder. Plugs are cheaper then pistons. Needle positon at 3. 1-2 turns air mixtures. 40:1

So good to see some 2 smoke content Kevin !! Just a quick one, I did notice you didnt mention heat cycling the motor to run it in at all ...

Man, this dropped at 11 pm where I'm at, just got up at 4 for work, gonna play this in the background today

Finally, a new video 😂 I've been waiting just for a new video because I already watch old content of yours on repeat🤣

Ok, you had literally a blown up hunk of metal that now runs for a half a tank of gas. Now you’re down to replacing coil/wire and plug! I’d say not a failure, but a another man’s memory brought to life. Good on ya!!

You saying you didn't want to seal the crankcase up & then find you left something out reminded me of my time working on motorcycles, and how shortly after I was hired another mechanic had a Honda 1-lunger completely apart when he quit and a different guy reassembled it...except for a thrust washer on the countershaft he found when he picked up his tools. Oh, the language!🤣 I had already developed a habit from working on my own stuff that EVERY part from inside the case was placed in order of disassembly into one of my 'egg boxes' -(a 'tool' I'd bought to do my own stuff - stacking numbered divided compartment trays in box metal boxes with latching tops) and as parts were later inspected after cleaning or replaced, they went back into the same place in the 'egg box' - and sequentially re-installed during the rebuild, so I only had to go pocket by pocket during reassembly, any part that did not fit in the pockets would be tagged with a numbered plastic tag (I got the tags and tabs at an office supply before I bought the 'egg box') and placed in the bottom drawer of the box, and the like-numbered plastic tab put in the pocket where it went in the sequence. As 'drawer parts' got installed I would pull the tab from the pocket, put with tag from part, and put both back in the long end pocket of lowest tray in order ready for next use. I could put masking tape on the trays to identify outside of case parts -vs- inside of case parts, so could tell at a glance at the 'inside case' tray and be certain I would not wind up like that guy struggling to invent new curse words for having to tear one partially or completely down and put an errant piece in - basically for free- as most shops paid a flat rate, and the more I produced with no re-do's the more I earned. Last place I was at was in 1971 I think, and only building the 750 K-3's as I had zero redo's except occasional part failures -(the shop 'ate' those). I WOULD do a single or twin if a guy was buried or having a bad day, and sign it off to them so they got paid for it, but a redo would have been mine. The guy freaking out that day made a DEEP impression, but having to often wait a week or more to get time to get back to a project of mine, (even though my memory is very good) let me rest easy about stopping and resuming right where I had left off, ALL of it learned from an older automotive machinist friend that had once even been a Cord automobile factory/dealer mechanic that helped me do my first couple of case splits, which prior had kept me from repairing those project bikes.👍🇺🇸😎

There's your problem lady 😂😂 the air filter looks like a chocolate Cake 🎂 lmfao 😂 36:29 @Junkyard Digs

Absolutly love the two stroke stuff 👌🏽😁

That box on top of carb is tors motion pro makes a kit to remove it and gives you almost twice the throttle length.... the exhaust use a silicone hose and hose clamps

Loving the variety. Awesome video.

Great video. I'm glad you posted keep them coming thanks
