Slimpsy1647545505 Posted January 12, 2009 Report Share Posted January 12, 2009 (edited) So I decided to go ahead and attempt a top end rebuild last night. It is my first attempt at any type of small engine work (or any engine work for that matter) and it was surprisingly more easy than I thought. So I get down to piston and this is what I find. The bike actually ran pretty well despite the piston being this bad. Should I worry about the bottom end having pieces of this in it (which there probably is) since it was running okay? I assume so since those metal pieces could probably dislodge and crack something even more expensive than a piston down the road. http://c2.ac-images.myspacecdn.com/images02/31/l_6f0fb2aeab7242568b13537fe7146879.jpg Edited January 12, 2009 by Slimpsy Quote Link to comment Share on other sites More sharing options...
ponyjr1647545514 Posted January 12, 2009 Report Share Posted January 12, 2009 it would be good measure to at least tear it down and clean it out. i wouldn't worry about checking bearings or anything if it ran well. Quote Link to comment Share on other sites More sharing options...

NTHER91 Posted January 18, 2009 Report Share Posted January 18, 2009 after you clean it out for gods sake follow proper break in Quote Link to comment Share on other sites More sharing options...
AJ Posted January 18, 2009 Report Share Posted January 18, 2009 it needs the case split to make sure you get all the parts out. brake in = let it run for 15 then cool down and then another 15 and cool down then your good to go. never had a problem with all the top ends i have replaced and doing it that way.
