just ordered a **** load of parts, i bought my bike for $400 and was told it needed a new piston. ordered a vertex kit and when it get in there the old one's pretty bad, i mean missing an entire side of the piston. i can see piesces of the piston down in the crank, my question is, HOW CAN I TELL IF THE BOTOM END IS TRAHSED?? I realy dont want to rebuild the bottom end, plus dont have the cash :bang:

sorry, but any debris that gets down in the crankase will probaly cause damage if not properly cleaned and checked out. Probaly have to split the cases.

As long as you have a manual for the bike, it won't be a big problem. Without a manual, it's a BIG problem.

Get the book, read it, and go have fun working on your bike! :nod:
