Mr Fast; thanks for the many words of wisdom! I've already purchased a set of VM30's, since this bike is primarily a once or twice a year mx bike and needs quick throttle response. As time allows, will eventually build a vintage flat track bike, perhaps using the 435 motor I'm picking up in May from former PowRoll rider Tom Street. That setup will definitely want the mega-carbs!
Also, you mentioned in a previous post the lack of proper chemistry in modern oils for break in and suggested some break in additives, what were those again?
Take care in Mexico, have a great time, ride fast and come home safe!
