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 😊😊😊
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!
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.
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!!!
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.
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 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 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.
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
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.
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!
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.
With a little luck all you did was hydrolock the motor with all that starter fluid and gas. Remove the spark plug and see if you can get it to turn over
@@muhammadmohsin3321 Bummer. Well sounds like its physically seized. You can take it apart and see what happened if you want but it doesnt sound like this video will help you
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
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.
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?
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
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
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
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.
you remind me of my dad... hahaha! "if it ain't broke, don't fix it." it says more than the words imply. and at a certain point in any vehicles life, you're better off just driving it until the wheels fall off... all of these sayings of course coming from a middle class mechanic who is at the point where he would rather walk than have to change a tire. :D
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 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.
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 ?
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.
Haha for real. Got out the kitty litter and soaked it all up. Really the only bummer about this video was that I only thought of making it a couple days after I had actually done it and busted it free, this was just a demonstration video
mrmaxstorey When I saw you rocking back and forth, I think I knew it was was loose. Typically, you'd see the tire skidding along the ground. Very good! Onward!
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
You may have hydrolocked the motor with the water. Try taking out all the spark plugs and kick it over a few times to clear it out. Next time dont throw dirt and water in your motor, have a good fire extinguisher on hand

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?
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.
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.
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?
Well yknow you can try to put it in gear and rock the bike back and forth to free it up, but honestly it makes a lot more sense to me to just replace the motor. You can buy a used motor on ebay for 200-300 and put it in yourself in 3 hours or so, these bikes its really easy. I have a few videos up of motor swaps and removal/installations, they are mostly on 4 cyl motors but the concepts are the same
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?
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
I swap master cyls around between bikes all the time. You gotta keep the same banjo bolt or at least have one thats the same size, but yeah master cyls dont have to be from the same manufacturer
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....
Yeah youll get that if you just spray starter fluid into the intake with no carbs. It could be a sign of timing off, fouled spark plugs, or no problem at all just drowned in starter fluid. Clean the carbs, replace the spark plugs, put it all back together and next time just spray a little starter fluid into the airbox if you are trying to start up the bike
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?
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.
@@mellamodiego8458 ok it's no big deal you didn't hurt anything. Take a piece of small hose, put it in each spark plugs hole and suck out the oil until it empties, and then you can refill with something that might penetrate rust a little better
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
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
+Mr ace Sure go ahead but don't yank that pullstart until the rope breaks. If you take off the pullstart assembly you'll see the flywheel bolt and you can put your breaker bar on that if you need to
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?
If it was only submerged a short time, and you changed the oil several times since and it is still running good, then Id say you escaped any real damage. Flooded bikes and especially saltwater flooded bikes usually seize much harder and have lots of corrosion, but I think you are gonna be ok
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?
Tom Walduck The WD40 will blow out if you run it with the spark plugs out. Just be sure to lubricate it well, turn it over a bunch of times,a nd follow up with a compression test after
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?
Basically the WD40 gets eaten up by the motor, burned off in about a minute and you are good to go. However, its unusual for a motor to seize from rust in only 4 months. If your motor is truly seized, it is most likely to be mechanically seized, either from eating a valve or spinning a bearing or something like that. Any motor can be rebuilt, sometimes its less labor intensive to replace it. Depending on how close you are to DC, I actually have a good CB400 motor i can let you have for $50. Regardless of how it goes good luck to ya
cheers for your reply its very helpful. unfortunatly ive not had much of a chance with work commitments to fiddle with the bike im also in the UK so cost even tho i would snap your hand off for the motor the postage/shipping will be horrendous. ive got a friend coming over possible at the weekend to help me remove the engine its going to be a long restoration but its a learning curve and theres no rush to it as ive got my gorgeous CBR 600 RR. thanks again
