man there is know way to say what would be perfect for your bike alot has to factor in there like air temp the elevation where u live,etc. my best advice to u is get several jets and change them till u get it right DO NOT RUN LEAN! Keep that dude on the rich side. Do plug chops to be sure. If u have a prob with any of this there are threads bout it all just search for it. If u cant find it pm me I will help u out!

With just a pipe, you aren't much different than stock. I wouldn't think you'd need much of a bump. Maybe a 240, 250? Stock is 230.

the guys with the FMF's usually land between 260-290 for a main, stock pilot

I was thinking to put 300 for main jet. What you recemmend to do?

i would buy a 260, 270, 280, 290, and the 300, and then start with the 300 do some plug chops and work your way down
