So I am about to attempt to find the right jets for my carb. I installed a 686 big bore kit and anticipated that I would need to. The purpose of this post is to see if anyone has some experience to save me some trial and error.
First off I am assuming that I am running lean since starting is a bit tough until warm and I’m getting back fires when decelerating.
WOT performance appears to be fine.
My question, with a stock air filter, box and exhaust has anyone else needed to change their jets and what size did they go with? Is it possible that I just need to do a needle adjustment and not change the jet?
I currently feel like getting 1 size bigger for the pilot should do the trick.
Also, has anyone has success with changing jets without removing the fuel tank etc? I’m thinking I might be able to loosen the boots and spin the carb a bit to get the bowl near me, then remove the bowl without pulling the entire carb off.
Any recommended brands? Buy a kit? DJ seems to be the most popular. I was going to just try my luck with local dealers and OEM jets.
Thanks,
David
