Even though I have searched the forum I can't find a picture or paragraph showing how to access the air/fuel screw. Can someone point me in the right direction......I have put on the new header, exhaust, removed the snorkel, put in the Uni air filter....now I'm running kinda of rough....just need a little guidance...

 

the fuel screw is set at the factory wrong then tamper proofed with a small press fit cap the you need to remove to access

the fuel screw ideally needs to be tuned with the bike running which is kind of hard to do, why many buy an extended screw with an handle on the end, Kouba brand is a good one.


pipe and airbox mods will require more than a screw adjustment, you need to go up on the main jet size. Until you do you may consider putting the snorkle back in.

 

1+ on what he said your most likely lean which is bad and jetting is in order

An excellent mod is to replace the stock fuel screw with a Kouba Fuel Screw.
