Just used this method on my fireblade, which has been garaged for nearly 20 years. It took an hour soak in WD40. Got it moving on the back wheel in top gear. Bit more WD40. 30 minutes later, it turns over on the starter motor. What a legend, thanks a million 😊😊😊

Hi, just wanted to say thank you so much for posting this, and all your other videos. They are fantastic. I was given a 1982 Honda CB750C and I'm currently in the process of restoring it. First time tackling anything like this and your videos are extremely helpful.

Your videos are so informative, I like the fact it has no bulls*+t involved, they are great to watch. Thanks for sharing.

I just started getting into motorcycle repair and restoration about a week ago and I have to say your videos and website are the most informative, resourceful, and most hands-on instruction that I've come across on the internet. I'm currently working on 4 bikes that have been sitting for 4 years and 1 that's been sitting for 25+ years. Thanks to you, I feel like I can get these beauties running again. Thanks for sharing your knowledge!

Rebuilt my carbs back in march...never would have even attempted that myself if not for your videos on the subject so just wanted to say thank you!! You the man...keep these videos coming!!!

The next time you do this use Marvel Mystery Oil. This was designed to do everything you are trying to do. It not only provides top notch penetration but it is is also a first class lubricant that will mix well as a fuel additive. So when you finally get the engine broken free it will not be hard to clean out the liquid that you used to free your engine. I have had very good results with it on many different things. It's the best.

Thank you so much, using your method I was able to unseize the motor in the pit bike that I just bought. It smokes heaps as the rings will need replacing but I had no intentions of bothering with the motor in it

I love your videos! I'm definitely going to pick up a bike with a seized motor.

Perfect! Been fighting with my 78 cb550 for a week on this. The trick was putting it in high gear and it worked in 5min. Cheers!

"Ride the piss out of it" - Solid advice : ) Thanks for the video. Good information and tips.

Methodical. Clear. Concise. A great explanation. Anyone out there with any success in unseizing a Honda 700cc Magna?

I mix up 50/50 Diesel fuel & ATF. Fill each cylinder to the top and let it set for a few days. Last engine I did was a 4 cyl. Diesel that had been setting in a field for 6 years with an open intake. Been running fine for the last 3 years now.

One of the most the most informative video on this subject

As always..great video. Appreciate the words of wisdom.

Another fine video Max. I'm sure many will find this useful. Cheers

Thank you, this was very helpful, have a rebuilt CB550 ( 74) that a schmuck Mechanic let sit promising to fix for a year but never got to it and now the engine is seized up. Gonna give these techniques a try. Fingers crossed.

This is exactly the information I was looking for. My '71 Yamaha XS650 will soon be running again.If it is only seized.

I use 50/50, diesel fuel and ATF Automatic trans fluid for my penetrating engine un-freeze, i have used this on several bikes and all bike runs great and are still running great.

I have a 82 yamaha maxim 650 it sat for years I could move the engine at all I did the processes that you show in your video and boom the engine is free thank you for the great advice

Hey Maxi what do you do to correct your ignition timing on an 77 tt500 if the t and f marks are rusted off the the fly wheel?

I haven't watched videos for a while due to working on my own bike and car. I see that you have upgraded your camera equipment and now have a camera tripod...its a huge improvement! Although your videos have always been awesome because of the content and the teacher, its nice to not have the camera shaking.. Again great video, thanks for sharing your vast knowledge!

I use marvel mystery oil, and put the plugs back in, let it soak for a day.

Mine has got to be the first situation you mentioned because I kept my bike in my livingroom. Especially during bad weather and the winter months.

Great Job! Most Informative!! Thanks!

dude you scored on that jewel!

Is there a follow up video to this bike getting unsiezed?

Informative and entertaining actually. Enjoyed your dry humor. Smiled every time you dropped the term "shit". Now . . . off to the garage.

Damn, this was good to know - thanks man! Love ur vids like these.

Hi Max. Another nice video. Some motorcyclists, especially in the States, recommend using Marvel Mystery Oil for unseizing. However I am not sure how available it is worldwide. You did a great job anyway ! Cheers, Roger

thanks Mr max that worked i got it running

Great video! "It's not easy to out it". Hilarious!

GREAT educational video!! Thanks

great vid :) just sold my first project bike

Always nice to watch :)

I just got one for $25 and boy am I happy I found this video (was getting ready to scrap it).

Ok Wd 40 and pb blaster! I got it turning now whats next just change the oil or do I throw anything inside the cylinde to clean up the pb and the wd 40?? Some help here plzzz

I've got a seized cb360t and have added penetrant in both spark plug holes. currently the bike won't shift either, even when I try to rock it as you show. Will rocking it back and forth still work if the shift is locked up? it's not in neutral but I don't know what gear it's in.

MARVEL MYSTERY oil work really well on alot of the boat motor i have done and the few motorcycles but so does WD

Thanks. Your the man. Sprayed WD40 straight through the carbs into the head, rocked it, and bubba bye baby.

Thanks a ton bro didn't know how that worked.

I have a 250cc scooter and my motor seized the electric and alarm works fine but the engine want turn over when I try to start it,I was going to install a new engine and everyone says the engine is gone,any suggestions please?

Great video. Well done.

thanks for this video i got my bandit 400cc seized motor to work again now only thing i have to do is get it running

hey man thanks for the video really helpful :)

ive got a 75 honda goldwing gl1000 been sitting for ten pluss years pulled tank flushed shook ann that got it clean or rust pulled carbs off cleaned boeles up flowts needle ste ats reinstalled freed breaks system drained now motor thought about marvels oil and desial fule flushing ithe gears only dont kown best way should i pull the case cap on top under neath where the carb linkage and put a small hose in there to flush the block and just let it wash and pull the lower oil drain plug

Good video man as always.

Another thing this happens to is front shock absorbers. Rain water will get in them and rust them and lock them down frozen. Drain them, use lots of PB blaster and back and forth motion or shocks until you can get them to wiggle.

I have found the Marvel Mystery oil work great, better than diesel fuel, or wd40, or just about any other stuff. Also adding some ATF into the crankcase helps clean and was the crud out, then after running a little while, change filter & oil as you said. I would run a little MMO in the fuel to lubricate the valve train while riding, go by what the bottle says to use. Hope that helps, it has for others, like me, plus it smells good. lol

Great info! Thanks!

this bike dont have many miles on it does it that stator looks like new

near boiling motor oil down the plug holes. obviously use metal funnel and copper or aluminum pipe.

Hey so I got a 77 sportster hasn't ran in at least I'd say 5 years.(oil was changed before it sat)Been stored in garage then my shed when I got it. Putting a chain on it tomorrow. Should I try rocking method first with out lube in cylinders? Or just spray it and let it sit overnight?

Great video thanks man!!!

Really excellent video. Thanks.

I was able to free up the motor but it freezes up again after I crank it over.2002 vmax 1200.Ihad to remove casing again and free with the breaker bar.

what if you get like a pop or back fire coming from the intake? So I removed the carbs and tried spraying starter fluid and then used pressed the starter button and got like a flame coming from the intake....

Did you put the spark plugs back in after the WD40? My bike engine is not seized but when I try to start it, it acts like it for a few tries. I think I am going to add that stuff and see. Thanks for the video.

Is the pb blaster trick a good thing to do before starting up after being garaged for the winter?

I have a 2006 Kawasaki ex250 with a seized motor. i took off the stator cover to expose the bolt connected to the crank. It is not the small bolt with the large bolt behind it, like on your Yamaha, only a 12mm bolt that unscrews counter clockwise, and barely budges going clockwise, until it gets so tight i dare not push it any further. I think, looking at parts blowup, this is connected to the crank, but it is small and looks fragile. Doesn't the Ninja have a crank bolt to try and unseize the thing? There are no video out there on Ninja 250 motors being free'd up. The local dealer said an engine rebuild is more expensive than the bike is worth and he could try and figure it out but 95.00 an hour to do it. Any thoughts on how to handle these 250 cranks?

Hi, I know it isn't related much to this video, but can you fit any universal master cylinder to a bike for the front brake, or does it have to be manufacturer parts

Great stuff mate

you do have video's of carb cleaning? just decided to ask a question about carborater cleaning.

Mr max I have a yamaha kodiak atv it sat for 2 years with a cover over it but its a automatic. and it has a pull rope should I try pulling it i stead of putting a breaker bar on i filled cycliner with wd40 it has been in it for 3 days .. what do you think

how much did you pay for the bike

respect to you brother!

Great video man! Super informative. Once you have unsealed the motor, you're draining all the WD-40/oil/water prior to putting the plugs back in correct?

Would this work for a 04 Yamaha xvs65 that just didn't have oil?

I used dielectric fluid in the cylinders worked a treat.

Hi Mr max I bought a quad bike 350cc,(Chinese replica of the yamaha raptor 350, it's called hisun. Parts are identical ) project, the owner said it just needs a wiring loom/harness. I bought a harness and installed it, and the bike was turning over, by jumping the solenoid with a spanner but it never started(battery is new) . With some advice I was told to try another harness and another stator and cdi. I purchased all the required parts from someone stripping the same model. I tried it one last time before installing the new harness and is still just turned over but no spark (even though I used a lot of starting fluid) I then put the new harness in and connected it up and it stopped turning over. I tried checking everything on the harness, everything seemed fine. After a while, I put the old harness back in and then too it no longer turned over. I tested the starter motor it's turning great. I took off the left motor cover and trying to turn over the motor with a wrench, I found it to be stuck, stuck. I left it for few months now, any idea what's going on with this bike , is it ciezed and unciezable or is it that the timings are out or any other advice will be highly appreciated Thanks in advance.

Man ... I am always so glad when I see a new upload, from you. So ... What if rocking or bumping the starter motor had worked, initially ?? At what point would you have drained and changed the oil + Filter ?

What a goofy way to design a custom intake.

Hi, I have a neco one b 50cc scooter, was riding out maybe 3miles or so oil line came lose with the clip, I noticed quite quick as the power went downstraight away so I stopped reconnected the oil line. I went straight back home, but scooter kept overheating every 5mins. and cutting out.... By the 3rd time my battery was dead so I couldn't try restart. I got home , I topped up the oil, let the scooter sit for maybe 12 hours and charged the battery for 12 hours. Now its not starting. it turns over and its spitting small amount of white smoke and it sounds like its close to starting but it just wont. Do I need to check anything engine wise? to see if this disconnected oil did any damage? or possibly clean anything? Just wanna avoid taking to dealership.... for a pricey fix. Thanks in advance

The stator and starter gears looked very clean despite the residue in the oil. Whats your take on a bike that was in salt water for 3-4 hours? (Hurricane sandy) its a 74 cb 550 that had some work done on it . Top end rebuild and a bunch of other stuff. I took the plugs out, kicked it over , a little water spit out , put plugs back in , it started up. I drained the oil, didnt see any white salt residue. changed the oil and filters 2 times. I think im ok, rode it many times since, but i'm still waiting for the UNSEEN bug to rear its head... any thoughts?

What kind of seizure would this be ( I was riding my Yamaha yz476f 73mph and all was great until immediately I hear some banging around in the motor and the back wheel locks up, but it will still shift through gears but the wheel will not move and it won't turn over?

did u find out why it would not shift?

do you know how to unseized a gsxr600 engine after lack of oil cause oil pan have crack on it ?

Great video. I just came into a 1970 BMW R5 that hasn't run in 30+ years. Will this method work?

A guy had this exact bike at the local street drags, had a swing arm extension and exhaust, beat EVERYTHING there, he was pissing the crotch rocket guys off, I was amazed, one hell of a bike

Is a vmax 03' for 3600 good deal in 2020? Ive watch all your vids for tips.

My carb caught on fire when I started my bike then after using dirt and waterto put it out just the gas lines were burned but my kick start got stuck would you happen to know why

I have a 2013 stomp with a stuck piston, i have dropped the engine out and turned it upwards so the piston is facing up and filled the spark plug with WD40, the kickstart wont budge and it doesnt like rolling in gear so i guess it is the piston. If i can manage to unseize it, what should i do next? And what should i do with all of that WD40 in the engine?

Excellent viewing as always. Hope the bike comes good for you buddy. What are those bikes like anyway looks a monster with real muscle. Nice looking too.

forgive me if im being really stupid but hopefully you can help. ive a honda cb400n superdream had it running about 4 months ago and now it wont. cant turn it over by hand or anything. if you fill it up with WD40 what happens to the WD40 does it just evaporate?

Good video, Max. I was hoping to see you bust this engine free by the end, but oh well. Now.. Off to clean that huge oil spin in your driveway! lol Watched it creep along during the last half of the video.

Great info here thx for sharing...also subscribed to your channel. Having some issues with my bike right and came across your video.

Is it possible for timing jump or Tappets to cause not being able to crank by hand?

+MrMaxStorey would it be possible to use an Impact Wrench that has Forward and Reverse? I think Impacting where it hammers it in short burts forwards and backwords on the bigger nut as you said. or would this tighten and loosen the bolt?

Would this help if my motorcycle ran out of oil while driving?

I have a honda 80cc dirt bike that is seized. Should all of these methods apply for it.

Very good!!

i did something stupid and poured some regular oil down the pistons after taking out the spark plugs….what do you recommend i do…i probably put 4 oz in each hole.

water in the cylinders= rust? bottom end bearings will rust too i had a kx 250 that sat it rusted the bearings to shit rebuild time.

Great video, but I need to know, did you get that bike [that I am jealous of BTW] running with just this procedure??

what about 3 in 1 oil

could have put on a small rubber angled snorkel on top .to keep rain out and still look cool

Hi there ! Nice video, did you manage to unseized it after all ? I just bought a Vmax with a seized engine

I use PB Blaster. Fill that cylinder and let it sit quite a while. Add some more.

Did you have to do something to remove all of the WD-40 from the cylinder before firing it up for the first time?

What ever became of the cb350 charity build?Did you sell it?

will this work on a 79 GL1000?
