Hi Guys..
My mates banshee has a problem, when you ride it it makes a softish backfire sound now and then(sometimes now and then, sometimes alot, and while making the sound the bikes power is not what it should be), but the sound is way louder when you remove the seat and airbox cover, so thought it was a reed problem causing to backfire through the carbs. Took out the reeds and tested them, they leaked a bit so replaced them all. Put everything back together and tested the bike, but the same sound is still there. The bike never used to do this, just started 2 rides ago. Any ideas on whats wrong? Or what to check next?
Thanx
