I can't seem to figure out why my bike is running so crappy. It has a Racefit slip on and a power commander V. I had it dyno tuned and it only made 150. The tuner got a lot of the hesitation out of it and the tune was decent. I changed the sprockets and all of the sudden the bike started running like absolute garbage (idk if there's any effect or just a coincidence) I put a cookie cutter map on it and it was running good for a couple rides then it started popping and stuttering again. It has a lot of hesitation now. I put the zero map and it was still running like crap. I heard stories of PCV being bad so I just completely disconnected it and took it off the bike now its running worse than ever. It sounds like it's running on two cylinders again and wont even really get the revs up at all. Feels like it's struggling to get to 6k. I'm at my breaking point pretty much. I have no idea what could be wrong. Please any help is great.
