wildwolf-131 Posted June 5, 2009 Report Posted June 5, 2009 well im wondering i wanna boost my shee to be real fast while being able to jump and well you know, do the mx stuff, juste wanted to know if a 4 mil and other heavy mods are good for that Quote
BellicoseBanshee Posted June 5, 2009 Report Posted June 5, 2009 A 4mm with the right porting will be a very good engine. Porting your cylinders is a must to get the most out of the increased stroke. :cool: Quote
fastrthnu Posted June 5, 2009 Report Posted June 5, 2009 uhm yea a 4mm with mx porting and stroke adj would be a very good move for mx. seems there are alot of mx questions lately, but I never see banshees on the track. Quote
Wildcardracing Posted June 5, 2009 Report Posted June 5, 2009 The increased stroke broadens the power band making the engine more suitable for many types of riding. Biggest gain of a 4mil is the bottom to mid torque gained, it will allow for more aggressive porting without having a "peaky" power band. But, as BellicoseBanshee said you need to get the right porting to get the full advantage of it. Quote
