Backfiring (After installing full exhaust + K&N Air Filter)
I have a question that I'm posting for a friend. It isn't actually a CBR question, since his bike is an R6 but I think it applies to all bikes.
We installed a Yoshimura R-55 Full Exhaust, along with a K&N High Flow Air Filter. He then got his bike tuned professionally.
Now my question is, his bike still backfires at high RPMS right when he shifts gears. Is this normal behavior for a bike with these modifications, even after a tune? And how damaging is the backfiring to his bike?
I figure a lot of you have similar modifications on your bike, and I'm wondering if all of you experience backfiring, even after you get it tuned.
