Alright, thanks for the plethora of help.
I already have a stock engine kit lying in my room, waiting for either a mountain bike or a cruiser with rim brakes.
What I plan on doing is comparing the stock engine to the modified one.
it will look something like this.
Bone stock engine vs pro "full race" engine
Home ported stock engine vs pro"full race" engine.
The race engine of choice will be the best of both worlds from two companies.
The full race engine, is going to be a crmachine bottom end with a bicyclemotorworks racing top end.
At least that's a good in theory combo I know of.
Has someone already run such as set up?
