4mill is to much my friend has one ane and all he does is spin so id rather build mine so i can ride it

 

Its all in the porting, gearing. A 4 mill doesnt automatically mean that its going to spin. Do some reading.

my friends is a 421 serval and i think the gearing is 15/39 he went all out with it and he has a hard time with it he thought he would be the fastest one but hes not even close my brother has a 88 shee with a stock crank ,65mm bore and a trail port and beats my friend all the time in the trails so i want to make mine a little faster then my brothers that why i can havethe best of both

your friend needs to learn to ride....as there shouldn't be any reason that a stock stroke ported bike is being a 421 serval setup. something is wrong....

^^
