AWR Posted March 6, 2009 Report Posted March 6, 2009 What exaust duration cpi oof pipe run well? 200 degree it's too high or it's okay . (bike for drag racing only on dirt track) if you are talking about stock cylinders it's 196-198 for inframe cpi's i thnk oof is the same duration-call cpi.thats who told me Quote
Tedder Posted March 7, 2009 Report Posted March 7, 2009 That combination isn't ideal. A 200* cylinder will develop optimum efficiency at an rpm higher than CPI's are designed for. Quote
