i have a catless midpipe and if I rev up to 5-6K and let to drop to 1.8K and pop the gas it will backfire and spit flames (sometimes) i almost made my little brother drop his bike under a underpass one evening it scared him so bad lol....said it shot out a orange and blue flame almost a foot out of the pipe...he might have been fibbing a little though on that....but mine does, supposedly.![]()
I actually wonder if I'm leaning out which is why I don't backfire. I 'm getting worried
