I am getting ready to put my WB E-Series slip-on and a rev kit on my 400EX. My question is what size jet would you guys recommend for this set up? My ride is still stock and these are the first mods I plan to do. I know in the future i plan to put on a K&N filter, will I have to re-jet again?

Thanks Mike

you will probably need to go from your 148 stock to a 152 main. Thats what i run and it does pretty good, I have a procircuit and a k&N.

should I do an K&N right away with that jet? How much difference will a new filtewr make?
