the more displacement, or stroke, the bigger cam you need to keep the peak hp at the same rpm range . my point being have you tried the 5's on a stock bore. if so how was the bottom.? not being the expert you all are ,i would asume a basic 730 would have the broadest curve with the 4's or 3's . either way everytime some one want';s to get a little more than what they have. its always the same answers you need to dump 3 to 8 grand
and do exactly what i did . dont get me wrong i want as much hp as possible , but not everyone want's to spend premium. i'm running around 70 + hp now and don't know if droping another 3 to 4 grand to gain 15 -20 at best on average, and get into the reliabilty factor is worth it.and i have heard they are reliable dont get me wrong. being a good fabricator i am going to see how i like the gsxr 750 motor since they are cheap and easy to get
and yes i will have web do a custom grind for me. and if i'm not happy . then the 800 is next. and yes a crank kit / cylinder kit may only cost 2700 , but after flywheel , new cams, ign, exhaust, or whatever else you dont have you end up around 3500.
i'm curious how long does the clutch last with 60+ torque, i had my hub and basket modded when i installed my last clutch. and so far so good. but im sure i just wasted time and was took. after all a clutch kit should be less than 200 right. them damn details.
