I have a 2001 Yamaha blaster, it is mostly stock besides an fmf fatty downpipe and silencer, and it has carbon fiber reeds, I can only catch the powerband in 1-3, and it takes a little bit in third, I have never hit it in 4th, after riding for a bit, my downpipe will glow red and pop and crackle, when it does this is cuts the throttle for a split second, and then goes back to normal, but it does it every time it pops or crackles, what do I need to look into to fix this?
