atcandbanshees Posted February 14, 2012 Report Posted February 14, 2012 Do big bore sleeves in stock cylinders help out that much I have a few buddies that have 4 mil big bore motors and I have a 4 mil small bore with pretty much the exact same set up just wondering if I'm going to be close or they going to stomp on me Quote
jonvia Posted February 14, 2012 Report Posted February 14, 2012 Do big bore sleeves in stock cylinders help out that much I have a few buddies that have 4 mil big bore motors and I have a 4 mil small bore with pretty much the exact same set up just wondering if I'm going to be close or they going to stomp on me my buddy has a low/mid port, cool head, billet reed cages, pods etc and i can kill him everytime. i have stock cylinder and stock head. i personally think its the rider that makes the biggest difference in racing.

mike0chek Posted February 14, 2012 Report Posted February 14, 2012 i cant see it being a HUGE difference if your mods are similar in the other areas Quote
sstaton1983 Posted February 14, 2012 Report Posted February 14, 2012 a stock cylinder big bore will never make as much hp as aftermarket cylinders.cheetahs,twisters ext....have much better port layouts. Quote
