steeler2169 Posted January 6, 2011 Report Posted January 6, 2011 If you get the Adj. +4 timing do you have to change your jetting since the timing is being advanced? Quote

brugal Posted January 8, 2011 Report Posted January 8, 2011 You may need to go up 1 size on the main. And adjust the airscrew. Quote
WINDYCITYJOHN400 Posted January 8, 2011 Report Posted January 8, 2011 Yes. Advancing the timing has the effect of leaning the mixture. You may be rich enough as you are, but nobody on a website will know. You have to check your plugs and determine that for yourself. But in a nutshell, EVERY change requires a check of your jetting. It's best to learn that first, before moving on to doing any mods. Plug chops = Knowing Riding and hoping for the best = Burn Downs Quote
