Would you spend $500 to gain 3 hp on a big bore engine??

i should since the 63 don't come with the 80mm clutch like it said it was. just double check with Tony Bacon and he said the only thing i need to do if i go for 71cc is exchange to a longer nut on the W5 to help eliminate vibration thread

Hey bud, it's not that the 63 don't come with the 80mm clutch the problem is the 80mm clutch don't fit the mcd platform.
Personally I would have gotten the 63 as the torque of the 71 is a bit violent plus the 63 revs higher and more rpm = more speed

i think it is a bit late to know bro but thanks for the advise, i don't want to revise my order again don't want to piss them off , since i live in CA, US don't have much room to run so top end may become useless.

63 may rev higher but 71 gives room to gear up, which gives more speed.

Just get the Super 85 and hang-on for the ride!
