Hello all, I have a moki 1.8 that I just rebuilt, new bearings, ring, carb, needlevalve, the full deal except the sleeve, will I have to go thru the full breakin procedure again since its a new ring only and not the sleeve too?? any advice would be appreciated, By the way Justengines is the way to go, I ordered my parts and had them in hand in a little over 6 business days. awesome guys to deal with!!!!!
