Yep, here's a little map of what each part of the carb affects

We just put a Yamaha R6 muffler on my wife's Ninjette and lost about three MPH. She says it will barely top 101mph (not by speedo, but by GPS- the stock speedo reads higher). I plan to rejet the bike shortly.

More later on the R6 muffler swap, what a pain in the titanium ass....

got it. But wouldnt this make my exhaust backfire even more since i would need more airflow not gas?

Putting a exhaust on without re-jetting (or re-tuning if you have fuel injection) is major NOOB status to me.

The bike is set for the stock exhaust from the factory. If you want the bike to run properly (better) with aftermarket exhaust you need to adjust accordingly.

My bike is in the shop right now for full exhaust and re-jetting.
