i had a 09 cr last yr, all stock, installed a FMF apex, denoided, and thats it, bike ran very good with minimal poping on decel or when chopping the throttle, i just bought a different 09 cr, fmf, ebr ecm, k&n air filter and de noided, POPS LIKE HELL on de cel, almost so much that i wanna pull the fmf off! fresh gas, former owner said its always done it, has 3600 miles, runs well, just the damn popping, any ideas??? | ||

Make sure where it slips together that it was sealed with some high temp sealer, or it will have small leaks. | ||

my 09 cr pops when i hold the throttle at a steady rpm! its at the shop right now! but they cant tell me anything! i took the k&n off thought that might be causing it! ive got a jardine and a preprogrammed race ecm on there! | ||

Which Erik Buell Racing ecm is installed. I just went from the Erik Buell Racing ECM tuned for a stock exhaust to one tuned for the HMF and the popping on decel went away. Plus the bike runs so much smoother now. Might be worth looking into. | ||

Mine is a 09 R fmf slip-on, K&N, race ecm programmed for fmf. It pops a little on decel but nothing major or terrible just a little bit around 4k rpm. | ||

bike has ecm programmed for fmf slip-on, k&n filter, and gear ratio adjusted to a cr, part # y0152.10az with the foot note at the bottom of the invoice stating what was done to it | ||

Check exhaust first, like Cptncreme suggested seal it up. | ||

removed exhaust, had high temp on it, cleaned up, put on fresh black high temp, let set overnight..test rode same popping, bike does not pop much at all cold, first 3-4 miles all good, or a cold morning/night much better, bike gets hot, pops likes a mother trucker |
