Well jetting threads seem to be popular. lol:blah:

But any ways im re jetting my bike for the air box lid mod, the other mods r in my sig. Well i can get it to idle and run at full throtle, but its getting from idle to full is where is bogs really bad. Now from doing some reading it sounds like i need to change the needle. but my question is do i need to go richer or leaner?

Current jets: 42 pilot, 155 main, needle 3rd clip from top.

thanks for the help.

You will just have to play with it. You may want to go lean. Remember, when you go bigger with the main, it richens the needle circuit also.
