Jetting from FMF to CPI

[brian_750]

I just put some CPI inframes on my bike today and got a dumb question but have to ask even know I probably have to. I my bike is jetted for FMF exhaust and I now put on the CPI inframes, do I need to have it rejetted?

I would "probably" go up 1-2 size mains and if you cant do it by feel do a proper plug chop for your mains. Better safe to start a bit rich then being lean. http://www.dfn.com/benkaren/plugchop.html

 

"Might" have to richen your needle position also. But for both, you will have to see how it is and let us know what it ends up liking, as they all respond a lil diff sometimes.

I'll just drop it off at my guy who does my engine work unless I get time to nail it out.
