jetting

I just installed a new muffler end cap on my daughters 150r it is a billet cap with the spark arester and now it is sort of lagging in the upper gears I was wondering if it needs to be rejetted or should I be looking for something else?

Sorry I can't answer your question. But did the insert quieten the 150r down any?

Since the S.A. is more restrictive you may just be feeling that loss of power. I'm not sure if just the s.a. is restrictive enough to make the bike run richer, but a size smaller main jet may help it.

It quited it a bit but is still plenty load
