Less stiff clutch center spring?
Posted: Fri Apr 28, 2023 2:30 pm
Looking to lower rpms and possibly gain a few MPGs... The 21G rollers added a few mph top end, but am told changing out this clutch spring might help as well? The stock rollers weigh 19.8 BTW. Is the spring that comes on the PCX the same tension as the stock ADV 150's?
thanks
