I currently have the airbox eliminatory mod on my raptor 660 and the jetting is off. I dont know if I should rejet it or return to the original airbox. Help?
this is a aftermarket exhaust. and the pipe is repacked to. it is at 96dbs with my raptor and a 10.75:1 compression. Oh ya, i also have a stage 1 cam and that 10.75 :1 piston that was used 1 season. both are in good shape. sell them as a pair for 100.I want an aftermarket exhaust it will probably be too loud though the stock exhaust is louder than my dads gutted 450 exhaust
No, the dead spot is because you're too lean from opening up the airbox - changing the exhaust will make it even worse without the jetting I suggested.I have the stock exhaust system on it right now. I was thinking about HMF but the getting both of the carbs synced is a pain in the ass. Is there any way removing the baffles and putting a new tip on it would even out the dead spot in the middle of first gear
