When you guys dyno your bikes what do you or the tuner shoot for A/F wise?
The only time I have dyno'd my bike the guy running the shop said he likes to see 12:1 which I thought was a little on the rich side but took his word for it since he was the owner/operator.
Anyways I recently sent my head to Rossier for some work and Joe told me my intake valves had lot of carbon on the backside which is an indicator of running rich. He said they like to see about 13-13.4:1 for safe max power.
Is this what you other guys are doing also?
