Mini Bike Crankshaft Broke in HALF, Let's Rebuild It! MB-200 BACK FROM THE DEAD!

Our Trailmaster MB200 mini bike has hundreds of miles and hundreds of hours on its modified high performance Jiang Dong 196cc OHV engine, and we just broke it's crankshaft in half! In today's episode we completely disassemble the engine, give the block a deep clean, and replace the crankshaft, install a Fire 265 camshaft, add a new rod as well as other bits and pieces. This was not a comprehensive engine rebuild- we should have torn down the engine BEFORE ordering parts, or just bought a new engine to start from. This engine has been abused over the years- ridden hard and occasionally stored in rainy areas.
Thanks for Watching!

Always have a good time here. We have our first of two TM MB200's delivered and running. Second test ride ended in a bent headlight, with mud and grass garnish. Didn't matter. We laugh it off and realize we more mature folks don't bounce so well. I'm 66 and Momma is 56. It's just another adventure. I don't know squat about engines but like the learning experience.

I would still order a piston and a set of rings just to finish the build and a set of valve guides wouldn't hurt.you can call it part 2 of the build / repair for the bike

Hi guys! I love your videos! I just wanted to give you a little tip. Even though assembly lube on the piston rings will work, engine oil is much better for seating the rings during break-in. Keep up the good work!

2:37 that was a good guess! I once broke the crank on a triple cylinder snowmobile like that and it still ran to get it home. the timing was way retarded but the way it broke it was able to keep running. I love strange things like that.

I have had they Chem Dip on my hands many times and have very sensitive skin. IT DOESN'T BURN YOU! it's not even as bad for yor skin as as a degreaser. You probably should have just used a degreaser to clean the engine anyway. It would have been cheaper and done a better job.

I do watch you guys very regularly, I will offer a little creative criticism... Why not measure the bore, at all? That is NOT how you hone a cylinder, first you need a rigid back hone that will correct out-of-roundness, second you need to hone at a linear rate that leaves a 30 degree crosshatch for oil retention, with the proper grit of course. Otherwise no oil is contained on the cylinder wall and rapid wear to the piston rings occurs. Did not see if you swapped the rings, but if not its a waste of time to hone. I guess you could have beady ball honed it with your eyes shut, and simply hoped for the best. Sorry I had nothing positive to add, but to point out wrong processes but being a machinist I couldn't help myself. Oh yeah, ATF (automatic trans fluid) works pretty well to hone with and afterwards using it with a good clean rag to clean the cylinder. The high detergent in it really scrubs the fine grit from the honing scratches.

That's a neat old simple go-Kart kinda bike that looks really fun. I'd never seen a little bike like that before honestly. And been around. Rode a lot of bikes! But the bouncy tires and and short suspension make it look like a fun afternoon! And I mean I'm 51 and own a much more complicated bike. STILL! I'd love to play on that Knoby tire bike for an afternoon HAHA!!! It looks honestly FUN!

Can I use your honing video to make a video to show people "How not to hone your engine"? You could have cleaned the engine with Simple Green, Use a small 400 grit dinkle ball hone, lubed with motor oil. Don't use wheel cylinder hones on engines.

I was out getting lunch after a job and saw these kids in the parking lot with their custom go carts and mini bikes ,maybe early junior high . They look like they spent some time on their rides ,some stuff looked like what you guys do . I asked them ,do you ever watch Cars and Cameras on ALpost ? one replied we watch them all the time . You have fans in Gilbert Arizona . It is awesome that you reach these young kids in a very positive way . Kind of reminds me of myself in the 70s building mini bikes from 20 inch bike frames and lawn mower engines with no brakes going down steep hills .

I don't get why you torque it and then bring it down then go back up because that literally does nothing you are adding pressure releasing pressure and adding pressure back that's all you are doing. I don't even use a torque wrench if it's tight it'll work.

If you hone the cylinder, do you need to replace the rings? I know best case would be yes but wondering if you can do it without replacing the rings. Thanks!

It looks like you left the broken bearing in the CVT idler shaft. Does that assembly have a spacer sleeve between the two bearings? The last CVT I got from GoPower Sports did not have one and I noticed that care was needed to avoid over tightening the retaining nut on the shaft. I installed a spacer sleeve which allowed me to apply much more torque to the retaining nut without having to worry about over tightening and crushing the bearings. STP oil additive contains Zinc (and it always has) to protect the cam shaft. Are you rethinking a spring event? I believe the Covid 19 crisis will be over by May.

I did a complete rebuild on a Polaris 400 sport four wheeler every single part was replaced spent 1200 dollars on parts for the old block. When a new engine is only 1800. But the reason for the rebuild was for an exploded rod bearing and the piston itself was in four peices.

The oil that you need is valvoline vr1 20w50 race oil at any chain auto parts store it is what we use in all race and flat tappet engines at work beyond break in. Also break in for those cams is critical use plenty of thick (like wheel bearing grease) lube on cam and tappets and run the 2000 rpm break in period WITH break in oil we use Brad Penn racing sae 30 break in oil for everything
