I went riding this weekend after installing my new-to-me E-series slip on. I noticed that any time I went above 3/4 throttle with any sort of load, the motor would sputter, spit, and do everything except go faster. I haven't had the plug out to read it yet, but I have a feeling that my main jet is too small. I'm running the dynojet stage 2 setup with the 165 main installed. heres some specs and I'm hoping someone who is running the same basic idea will tell me what is wrong. Thanks in advance.

Air filter: K&N with outerwear wrap
Snorkel opened up at the intake end
E Series slip on with 8 discs in (took 4 out for sound purposes)
Carb: Dynojet re-jet kit, stage 2. 165 main jet, dynojet needle on #3 groove, fuel screw 3 turns out from closed.
Spark plug: stock plug/ heat range
Altitude: <150ft above sea level
Sometimes I ride with the airbox lid off, not this time though. SOMEONE HELP ME!!!
