What variatorrollers and jet do I need.
Going to install a Yasuni R (for piaggio) exaust on my Aprillia SR5R (2011) carb 2stroke. What weigt rollers should I get and what size jet. Someone advised me to get 7.2g rollers (that would mean going heavier than the one's i have now (6.4g). And a 6mm 50-74 jet. What does 50-74 mean? Is it not supposed to mean 1 number?
