Can someone tell me how to remove the screws from the bottom of the carburetor without ruining the screw heads. I put a new pipe on my YFZ and was going to rejet it, and tried to remove the screws from the bottom of the carburetor they are some dam tight that I screw up two of them so I gave up before ruining any more :angry . Can I get to the main and pilot by taking the big nut from the bottom?
Thanks for any help on this one.

If you're changing your main, pilot, or jet needle, you don't have to drop the bowl from the bottom of the carburetor. The main and pilot can be accessed through the 14mm cap in the bottom and the needle can be accessed from top using a 3mm and a 4mm allen wrench.

Thank you, I'll try to change it this weekend.

PS - it's a 17mm bolt at the bottom of the carb, not a 14mm.
