87, gt thunder stage 3 porting, wiseco piston, .040 over, great compression, good clutch, also has a lightened flywheel. This motor is very fast and revvs out like nobody's business:devil: The bottom end was gone through a year ago by the previous owner and everything that was worn was replaced. This motor has NEVER left me stranded or disappointed. I changed the oil after each race (there was only 2 on this one) and I changed it every 3 hours or so of just riding, whether it was practice or just putting around. The air filter was also cleaned and re-oiled after EVERY ride over 5 minutes.
