Your dog had so much fun chasing you!!! Hahahahaha that was awesome.

You've come a long way since you started making videos Joe. People used to put you down and say you did shit janky but I think your a beast. There's nothing that you can't fix

The garage door has a co2 sensor that opens up the door. They've been around for a while and are a really good asset to have when you warm up your car in winter or run machines too long like I do sometimes and don't pay attention. Pops

great video, just a tip when soldering. you should heat the wires not the solder. the heated wires should melt the solder. that way you know you have a good connection.(sorry for possibly bad english)

I just started watching your videos. I like how you diagnose. I’ve been a boat mechanic for 35 years and very few guys I worked with can diagnose their way out of a wet paper bag. Hats off to you sir!!

So funny! As I started this video I said my machine did the same thing and it was the spark plug and I go well. Maybe there's something else with this machine and then it ended up being the spark plug. Awesome video!

Great job as always! I am also impressed with the energy your little dog has, very cute

i love starting my mornings watching these.. specifically your videos i don't watch anyone else lol

Nice work, Joe. I liked your thorough and methodical approach to fixing this one. And Vinnie is a delight -- makes me laugh!

For what it's worth, that solder did not penetrate, you just stuck it to the outside of the wires. Need to heat the wires with the iron so that when you touch the solder to the wire it melts.

Dude, you provide so much value to me and your viewers. You’re a damn good diagnostician and mechanic man. Great work.

Try getting a tube of rosin flux for your soldering, and a lead base solder. That cheap rosin core solder doesn't flow good. You will see a difference in your repairs.

First time seeing this channel. This was a good instructional video for me on how to diagnose what might be going on with my raptor. Great work

Turned this into a very solid KZfaq channel brother congratulations on all of the success you’ve had on KZfaq & hopefully my channel gets somewhere even close to the subscriber count you have to date!! Keep doing what your doing & anyone who leaves a hateful comment well I’m sure you know it’s just the way people are love the videos keep look forward to future content!!

Hey Joe as a thought could you get a spark plug tested that is clear and hook the other end up the the plug while it's running and as you rev the engine you can visually observe the spark as you climb up the rpm

Hey mate, I'm an old Aussie who has just started to get into bikes. Got a kz200 and some tools ... thanx for your great videos, I've learnt so much in the last few weeks ... And my favourite saying now is "it's not horrible". Tell Vinnie I said hi.

That pup is almost as fast as the bike in that space lol he can rip! The bike turned out sweet as usual.

Way to go Joe ! Great job on the mystery fix !!

You could have an air lock in the oil lines, any time I change my oil and filter, at the same time and try to ride right away, the oil tank always over fills, I have to crack the lines to the top of the head and back of crank case. If they sit same thing can happen.

Always use Rosin core flux on electrical wiring! Plumbers flux is acid core and will corrode the wiring. Tin/lead solder is what to use. 67% tin, 33% lead. Again, no plumbing solder!

Hate seeing nice equipment with no maintenance and apparently stored outside or under a tarp at times....and then people wondering why things start going wrong.

I’m highly addicted to your channel! Love doing this stuff. Thanks for sharing. God Bless

Goddang-it Joe, when you lived in town I thought your neighbor had a lawn mowing obsession but now you are out in the country and I still hear a mower running I am beginning to think it is Jade who has the lawn OCD!!!!

I'm very happy you went gloveless in this repair. wearing gloves is fine for the dirty and rough work, but must be able to feel without the glove for the fine work you are doing.

I had a bad cdi box that acted like that idle all day but wouldn't rev up

When you solder you need to hold the soldering irons tip against the wires until it is hot enough for you to feed the solder in and wick into the wires. The way iv watched you do it in multiple videos you're just creating a poor cold solder joint that will most likely fail. Other than that, good stuff as usual.

love your videos. Great work . massive respect from the UK 🤙

Great job Joe! Auto mechanic told me once start with the basics and go from there...

5 minutes into this.. I'm thinking right off the bat - to me - it sounds like either a fuel / air issue or a timing issue.. definitely could be something else, but what it's doing is pointing me there. I see why he would have gone CDI, but man being a parts cannon and throwing parts at stuff is really not a great way to fix things. Diagnose, identify and resolve. I'll bet you get it figured out. You really have a wonderful channel here, I'm glad you have taken the time to turn on the camera and share your love with us!

Hi from Croatia,im Huge fan,Nice quad💪💪💪

Good job. Fixing these can be a pain. I bought 1 used and went through same stuff. CDI, carb rebuild and jet, and valve adjustment and she came to life

You wouldn't believe how many bikes I've had come in that was just a valve adjustment to fix, especially ones owners have mis adjusted. And ones owners have put new top ends on themselves. Always run factory recommended plugs. In my experience the iridium plugs just don't cut it. Great vid.

You doing the valves reminds me of when i did my ktm's a few months ago, my ktm had its first valve adjustment in 19 years it did. Runs better now. Intake valves were way too tight no slack at all and it was loosing alot of compression.

Mine is a 2002 as well. With the 686 big bore. Almost like a different quad. Hella fast. Great vid!!

You are the best! I hope you charge well for your work, because you deserve it!

I have been watching you videos for some time now an you have a very big help an you have taught me so much so thank you so much and I appreciate the videos so much what you take an turn it into is awesome

Keep up the good work !!!!! Love this Channel and I have a lot to Learn!

Pro tip... When you solder you dont heat it on the tip of solder gun and paint it on you suppose to put the heat on the opposite side and put the solder on the cold side and let it run to the heat.

Also a sensor and a switch are totally two different things! A sensor changes ohms where a switch is on or off...

Clean that oil screen in the bottom of the oil tank. It could have a hard time circulating back to the engine, causing it to pool in the reservoir and starve the motor. Aside from that, another great video bro.

Morning joe. Great vid. Looking forward to the next.

Nice one Joe, your place looks nice too👍

great video, bro. amazing machines. Bobby was chasing that thing! haha!

Man i wish my local Powerspot KZfaqr would help out his subscribers like you do. You are one of a kind Joe, too bad I couldn't get my TRX 450r to you to dial in. Keep up the great work.

Minted job joe knew you would have it tip top in no time nice quad good to see vinnie as well he's a cute dog mate take care and all the best 🔧🔧🔧👍👌

Back when I was a kid in the 70s we use to keep a new plug and a spark plug wrench in the tool box under the seat. Spark plugs can go out at any time. They can get fouled and you can wire wheel them. But a lot of the time they just go dead or almost dead. like the one with yellow spark. Very common reason bikes will not spark. You got that baby fine tuned. 660 woowee! You should race that guy. LOL It pretty quick though.

Come on Joe, time to get some good tools lol

when i saw that plug it looked wayyyyy too fried. picky motors that need high dollar plugs ! good thing you fixed the other issues tho, I think it was a combo, bad plug, probably bad fuel, valves way off, and wrong jets. great video and diag !!

Youngblood are the best I've ever seen I've been around for 77 years and you are a top mechanic I thought I was good

You are living my dream Joe! Great video!

So no one could find a bad plug😂 i don’t know where this person lives but they are in bad need of atv mechanics😂 good job

Great work mate love the channel UK

You never cease to amaze me. I am not a mechanic, but I have learned so very much from you. Oh, and by the way, Vinnie needs a haircut.

Sounds like the timin ain't advancin

I haven't subscribed yet, but I should have, you do great work! You have way more patience than I have. And I've been told I have alot of patience! You take on some of the most difficult jobs! I enjoy your work and will subscribe, I lke Vinney!

Jets on cheap china carbs are never marked . Use the original .

Your patients is exemplary ...I'm tuned in

Where are all the haters talking crap about him now? I would like to see you try and fix something like this

Yeah, having a Warrior, first time you fired that thing up I thought to myself that sounds a lot like that parking brake circuit messing up. I've fought that battle before too. All those other issues likely just made it worse. Awesome job again. I really look forward to these videos. When are you going to start doing Miata's ?? (evil grin.... I just got a basket case NB in my garage to try and reassemble with my son, and these "how to" videos are an enormous help)

you're telling me nobody could change a spark plug and you're the only person 🤣 .

Love the knowledge bro thanks

Sometimes aircraft will cause garage doors to unexpectedly open. Or your house may be haunted! LoL

The average person that will watch one may not get excited about it as I get. I can do the work and have done it a lot. A dealer ship sold me a 500 tripple two stroke all locked up. I brought it home and for a week or two worked on getting the piston stuck loosened. I clean out the tank and the carbs and decided after doing all this work on it was going to take it for a ride. I rode thru Chichago during rush hour and then up to Canada. I sprayed chaine oil on the points and fouwled them out. Got stuck in Canada. Had to get the truck and go back and get it. Now i am looking over four wheels right now on marketplace. Tried to get the guy to bring me have to stay in at home here, a four wheeler and a cub tractor too. Some one else go the four wheeler. Am working on getting another one that I jewed him down on. It shut off and wont go so I know that it will be some work to be done on it. I just don't have the thing we hit with the hammer to loose the phillips screws and the fly wheel pullers. I am almost 70 years old now. Yet I have wrenched on a few of these too. I have worked on the mopeds too. Just changing the front or rear tires is fun, and in addition just do the breaks when doing the tires too. The drive belts need to be checked often too. I would love to have some land just like one has too. Paul in Ohio

Nice JoJo . Appreciate you buddy.

Love the videos man!

You have a cool approach to problems and good mechanical skills, nice work. Shame you don't live where I could get you to work on my bikes.

thanks so much for fixing it!!!!

My Warrior 350 acted similar and it had a crack in the rubber intake manifold.

Lol so wierd it idled perfect. Sounded like carb issues to me.

Joe. You are the man. Bravo. 👍

Congratulations another good video. If you can do it I now should be able to do it. Ha Ha !

Wow we got a big head on this thumbnail!

Its sweet that the customer can watch your video of there bike being looked at. Probably nerve racking too.

Vinnie trying to catch you, is so funny.

I enjoy all the yfz videos. They help me most. I have an 09 yfz 450

Video awesome but the best part by far is the dog having a great time running around at the end

what wire harness did you buy to fix the bike mines are burnt too

Right off the bat i am going to say weak spark. I had a similar deal on an old two stroke with points. Points got dirty and killed the spark... couldn't rev over 1,000RPM and as soon as you out a load on it, it would bogs down. Now, going to watch the video. Edit- Pretty close!

Nice work!👍🏻

Cool beans... nice deal!!

Knew it wss a spark issue..good freakin job Joe !! 😃👍👍👍👍👍👍👍👍

Intake carb boots are a few millimeters too short on O.E.M boots, and they keep popping off. But you can buy aftermarket boots from UPP that fit much better and won’t pop off. And the grinding, (some say whining) when you go to start it is the starter clutch. Raptor 660’s are well known for this. Best to put a one way starter clutch.

I love your house and yard

Put a big bore kit in it for up grade...ur puppy gives all it has 2 keep up.lol.....love it...Great vid...b safe.peace.

Great job Joe🤪😁😁👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👍🏻👌🏻👍🏻💪🏻💪🏻💪🏻🏍🏍🏍🏍

Not sure if you had done it or not but alway remember to clean the screen in the oil tank when Changing the oil, it's on the oil line that runs to the engine

Check the stator.& Pick up coil to tom. It's must likely halfway fired out to. Yes that one way bearing could be sherd off witch means the timing is off A course to. Along with hooking up the electrical wiring to something different l.,or to eliminate something to will affect the wiring harness.& Charging system on them to. Check out the voltage regulator/ rectifier box.

Nice work, mine does the same thing, it was the carb, i fix it and now everything is ok

Need a set of torch tip cleaners to measure your unmarked jets

So how are you the last resort when it came to you running it's easy if it does when you give it throttle it's either fuel delivery or something electrical it already runs

Excellent job bro very good mechanic

Great video man thanks !

My buddy just got a 660 had it rebuilt such a cool machine it looks good sitting with my 700R

Love the vids and youve worked on a number of raptors now. Ive officailly got all the parts for my 86 kdx200 to make it run ride and stop , all i need are the platics, cant find those anywhere

good job ---they are nice 4 wheelers

Cheers brother ✌️

Damn no electric tape or anything lol…Good luck with this one joe!!

There was a ktm chasing you on the 4wheeler ohh wait that was your dog 😂Awesome videos

I've had a cdi box act like that before, actually ran faster in reverse than in first gear however that happens. Swapped in a backup cdi and it ran perfect. Weird as hell.

That electrical can be a pain. Good job brother.
