You're full of shit bro, or I'll just give you the benefit of doubt and say clueless.
3rd gear@7K will get you to about 86mph.
@13.75K 169mph (like RNBRAD stated)
My calculations my not be exact but are much closer than those than yours.
Is this only when the engine is cold? If so and you adjusted everything properly like you said, it normal. You may be able to eliminate the problem by switching oils.
You'd be throwing away your money unless you mods called for it, ie more than 7* advanced timing or compression above 160# or so. List your mods and these guys will be able to give you a better answer.
Has anyone else ever imagined what I'd be like to operate a 2 stroke car? More specifically, a car with a similar "weight to horespower" ratio as the Banshee.
Bought a swingarm and some tires from him a while back. Swingarm was here the next day but took nearly 3 wks and numerous emails to get my tires... wtf?
