f/a help with jetting.
hi i posted this over in pwctoday.
i installed f/a on my xl760
stock is 1.5n/s 115gr spring and 135/137.5 jets
so i first went to 1.5n/s 80gr spring and 137.5/140 main jets still lean
then i went 1.5n/s 80gr spring and 145/145 main jets still lean.
i think my pop off is too high for the f/a im using right now with this set up my pop off would be 38psi im switching to a 65gr spring and trying it tomorrow and my pop should be 32psi. im hoping this 6 psi difference would help. does anyone have and suggestions or have put flame arrestors on a xl760. that know what else i need to do?? thanks in advance.
