Low rpm bog/fuel screw help
Posted July 01, 2016 - 01:55 PM
But what I don't get is I can screw in my fuel screw all the way and it doesn't kill the bike. How can the stock size 45 pilot jet still be too rich even with the exhaust and filter?
When I bottom out the fuel screw the rpm just raises. I've got from a size 50 pilot to a 48 and now I'm down to the stock 45. No matter what I can tighten the fuel screw all the way and the rpm just increases.

You have changed the pilot jet to the correct size.
...but you have ACV compensation on that carb, which makes in nearly impossible to do a proper fuel screw adjustment, and why so many people block it off and go to the YZ specs

Don't forget to buy a 100 Main Air Jet when you block off the ACV!
Thanks again for the help KRANNIE.

....oh and the fuel screw should be brass, not alloy....because the alloy one have a taper to them.....and the fuel screw affect nearly only the idle, and has not bearing on bog.
That's the Apump.
