dcalsv02 Posted March 2, 2012 Report Share Posted March 2, 2012 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. Quote Link to comment Share on other sites More sharing options...

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 Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted March 2, 2012 Report Share Posted March 2, 2012 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.... Quote Link to comment Share on other sites More sharing options...
shakar Posted March 2, 2012 Report Share Posted March 2, 2012 (edited) 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.... ^^ i agree........... but im also curious about the ss serval and what kind of #'s there capable off?or how the power compares to ported ss topend any1 have experiance with both set ups?? thanks Edited March 2, 2012 by shakar Quote Link to comment Share on other sites More sharing options...
