Fine tuning with TuneBoy
With the TORS, cat bypass, and triple K&N's I am running custom tune # 20050_3 from TuneBoy. Wayne, at TuneBoy, mentioned this should be a good starting point. Now, that I have thoroughly test riden the bike, there is no question that the power and torque have significantly increased.
A couple of times I noticed backfiring through the throttle bodies as I blip the throttle while downshifting. I'm assuming this is being caused by a lean condition at lower RPM's. When this backfiring occured, the air temp was in the 90's. In addition, I have Baker Air Wings which were directing a lot of air flow right on the triple K&N's. So, I'm wondering if these two conditions could have added to the fuel mixture getting lean. So, my question is; has anyone gone into the 20050_3 tune and richened it up a bit at low throttle positions? If so, I would be very interested in the tune you ended up with. If fact, any comments anyone would have concerning this would be greatly appreciated. Thanks-Ken B.
