CTD Power Posted March 28, 2008 Posted March 28, 2008 What are you people running out at dumont with your 400's? I put a full yoshi exhaust with k&n filter with no lid stage two,and was wondering what main jet you used? Quote
Dune Cruzer Posted March 28, 2008 Posted March 28, 2008 I've got the Alba Racing pipe kit on the wife's Z400, with their supplied 155 main jet. It doesn't seem to be running quite right. May need to go up a size or two. Trial & error you know. Quote
