boonman Posted November 24, 2003 Report Posted November 24, 2003 What did the top end (piston mainly) look like the last time it blew? What happened to it? Was it jetting? Detonation? Improper machine work causing the ring to catch and break? There can be alot of determining factors here, and something is definitely wrong. You need to get it taken care of immediately before you harm things further.... What happened this time it sounds like it overheated. And possibly hot siezed. Quote
raxen Posted November 24, 2003 Report Posted November 24, 2003 What did you gap the rings to when you rebuilt the top end and how did you break it in? Quote
Banshee109 Posted November 24, 2003 Author Report Posted November 24, 2003 i cant remember what the rings were gapped at but my dads friends helped me on the last rebuild. we didny hoen or bore the silinders we just put some new rings and pistons in and started riding. the break in he said just dotn go wide open and if you do back it back down immediatly afterward. so thats waht i did the first 10 hours then i just went all out. ive been using 93 octane gasoline wiht klotz r-50 premix. i dunno the jetting b/c im not to good with carbs. but im running dynoport pipes and silencers, boyeson power reeds and k&n air filter. also ricky h.o. stator. ithink taht s all the major motor mods. the last time i rebuilt the pistons looked like all black and little crator like things in the top of the piston. and on the right silinder near the exhaust port was all like dented or flatened. and this time the right silinder is what broke the ring again. anything else or more q's just ask. thanx alot guys. l8er.

boonman Posted November 24, 2003 Report Posted November 24, 2003 Well, the pits on the one piston sounds like detonation, and the right side (the one with the exhaust side damage) sounds alot like a lean condition. Was there an air leak? I am assuming you already tore the top end down. In which case you can't do a leakdown test to determine if there was an air leak present or not..... Quote
Banshee109 Posted November 25, 2003 Author Report Posted November 25, 2003 i dont thier would be an leaking pomble never leaked before but if like sya the water pump gasket or somin was bad and it leaked alot of antifreeze that would not be good right?? now when i rebuild it should i hoen it or bor it over. and would my stock 87 crannk take the extra compression and what would happen if i ported it??
