tore apart my brothers shee engine for crank seals, and wow what a f@#$%ing mess. the first thing we found was both jugs are junk because someone had done some horrible home style port work, and must of knicked the inside of the cylinder wall because a ring was bent, destoyed the piston as well, but it still ran like that we where going to do the top end soon anyway. so we keep going and pulled off the clutch cover and find a little washer didnt know what it was at first, but after we pulled off the clutch basket, we found it was for the kick start idle gear the only thing holding on that gear was the clutch basket. so we get the cases split and find theres no cir clips on the output shaft that must be why the end of the output shaft where that idle gear goes was sheard off making that shaft junk.the cir clip on the right side of the crank was missing as well. the good part is it dont seem to have any case damage. we got a new tranny and top end of flea bay, had to go to the dealer ship and order new cir clips waiting on them now to put it back together.i got the shift cam back in and the shifting forks in, and the shifter shaft i think thats about as far as i can go with out those damn cir clips. anyone have any tips on puting this back together? seems pretty strait forward and i have two books.

Use Yamabond on the case mating surfaces and I use ATF fluid on the gears before I assemble it completely. Use a GOOD torque wrench. The bolts don't take much before the break.
