Fuel Screw Adjustment with Mods
Hey all,
I have a 2019 DR650.
PO installed the procycle jet kit and modified the airbox (opened it up by cutting off the top.)
(see here: "https://procycle.us/product/85?srsltid=AfmBOoo9PWZr0IXrhP2y4OZfuHyf-4DnfPzZSV85u7itIH9ts2Vh\_jN1")
He also added a Lexx MXe exhaust kit
Recently, the DR sat for the winter. I installed an Acerbis tank and took it out of its slumber. It was running okay for the few times I got to ride it, and then eventually started giving me trouble. It got to the point where giving it throttle would bog or kill it, so I took out the carb and gave it a good cleaning.
I replaced only the pilot jet (42.5) and cleaned all else. In cleaning, I made a mistake. I should have taken exact note of how many turns out the fuel mix screw was, but I didn't. That said, I know it was more than I was expecting (somewhere between 3-4 turns?). When I reinstalled it, I turned it out 2 full turns and called it a day.
After reinstalling the carb, the bike runs like crap. Idles meh (sometimes a little inconsistent) WHEN it starts but turns off eventually. Sometimes throttle sounds fine, sometimes it kills the bike, sometimes it just acts a little wild. Almost every time I release the throttle, the exhaust pops.
I think that the problem is with my fuel mixture. As far as I could understand, the exhaust popping means the mix is lean, which would make sense if I reinstalled the carb with the fuel screw an additional turn or two in from where it was.
Does anyone have any idea how many turns out I should have it with the mods that have been done to my bike? Taking the carb in and out isn't the end of the world, but it is a bit of a PITA, so I would like to try and have a plan for how many turns out I'm going to adjust it.
Thanks for your help guys.
