Some pics of my rebuild

Well the engine rebuild vids that got posted make this seem kinda crappy but figured I'd still share anyways. Everything went smooth with no hickups, well I did manage to lose the ball for the clutch actuator rod. After looking around I found a wheel bearing to a scooter that i stole a ball outta, perfect fit. She fired right up after I remembered to turn the kill switch on lol

Cylinder and my .30 over piston after machining

My Crank after I sent it out to Vince at Mr.Crankshaft to get rebuilt, he did an excellent job like always, I highly recommend him. He charges $140 for a blasty Crank.

Ive Ran a tank of gas through it, it runs alright, not 100% though. It starts first kick and idles perfect, but it kinda breaks up in the midrange. The reed block has a little peice of the rubber missing where the reeds seal. I'm gonna get a new cage and go from there.

Piston kit $85
Main bearings $60
Gasket kit $30
Crank Rebuild $160 with shipping

Vitos full bolt kit was $40 or something like that.
Yamabond, carb cleaner and other stuff was about $25

So about $450 for being a dumbass....... Man I wish I didn't just add that up, Now I feel bad lol That's more then half of what I paid for the bike to start with.

i dont know clearly about these engines. i guess it's difficult to rebuilt them.
