I just purchased a new full comp yoshi. I have done several searches for this topic but no real conclusion. My question is simple, What jetting did you do and what airbox mods do you have with it? (Im going with Mikuni jets)

 

I have 167/172 in mine right now but I have'nt had a chance to ride it much since I put them in.I had 160/165 and felt lean on top and had white spots on the plug.
full yosh
no lid
25 pilots
mixture screws 1.5 left 1.75 right

 

thanks for the info
