I have a question for the Guru's out there, I have a K9 750 with a full exhaust and bmc filter and PCV.
I have had the bike properly tuned on the dyno and have recently purchased an autotuner for the PCV. My question is, what target A/F ratio is recommended?
I have tried to contact the tuner who did my current tune however he isn't in today (off running a stall at the motorbike expo here this weekend). I was going to try to get this installed this weekend.
I have tried to search but I couldn't find the answer I was looking for. If somone could point me in the right direction I'd really appreciate it.
13.4 for a 1000 - 1500 rpms before your bike normally starts building big power will smooth the delivery and make some extra mid range gofast. Then drop it back down to 13.0 / 13.2 where it starts normally building power. I'll go 13.5 on the top end of things on a track bike for some extra power on top.
