Looking to change the jets on my Eigers. My question is why would someone need a "jet kit" when the jets are available from jetsrus.com for less than $8 each? Also do i need to re-jet all of the jets or just the main? I was thinking about jumping up to a .135 as that is what I have read is the best. Will I need to readjust the fuel air mix as well when I do this? Thanks i advance for any help.

 

I bought the jet kit cause I wanted the jet needle in addition to the selection of mains. I wanted to go as rich as possible. Go ahead and make any airbox and exhaust mods as well as that typically allows for an even richer jetting. I backed my idle jet out 2.5 turns.
