[QUOTE="rmc_olderthandirt, post: 1310109, member: 68872"] The quickest, cheapest and generally most effective jetting adjustment is to change the needle height. On most bikes it is pretty simple. Unscrew the top cap (this is where the throttle cable comes in). When you remove the top cap the throttle slide comes out with it. There will be a needle that sticks out beneath the throttle slide. Where the throttle cable connects to the slide there will be an adjustment to raise or lower the needle. Raising the needle opens the needle jet earlier, making the mixture more rich. The needle is the dominant factor for throttle settings between 1/4 and 3/4 and has a fair influence on WOT. Try that first, as it doesn't cost anything and is easier to do. Rod [/QUOTE]
