How many of you have rejetted when adding a slip-on? Has anyone noticed any negative effects from adding a slip-on without doing anything to the carbs?

No need to install jet kit do a search on shimming needles or shimming carbs it all youll need

I installed a Yoshi slip on and havent noticed any flat spots. Probably one day when I'm motivated I'll shim the needles though.

I have Micron bolt-on AND K&N filter, and no jet kit. I did notice power difference, but that's about it. No negative effects except for fuel economy. I get about 40mpg (I do drive it hard for the most part, and I do have a -1 front sprocket which raises the rpms).

i would only shim the carbs with just a bolt on.
rejetting is only relly needed if your doing alot of mods or a full exhaust system.
