If you want to check your valve adjustment do not do it after you have ran it. wait overnight until it's cold. Than remove all your front plastics, seat and fuel tank, remove the two valve covers.10mm bolts, remove the sight plug on the flywheel cover (left side sitting on bike about the size of a quarter and slotted.). It's the same one you looked through to find the "T" mark.remove the spark plug so you don't have any compression. slowly turn the engine over until you line up the "T" with the mark on the cover. check and see if your rocker arms are loose if they are tight rotate the engine one more revolution back to the "T" agian. now you are at TDC on the compression stroke. each rocker arm has a 10mm nut and a tiny square on top of the bolt, break the 10mm stop nut loose being carful not to turn the bolt. You want to see what the gap is before you start. and get out your feeler gauges and slide it between the valvespring and rocker check the clearance. I think you want somewhere around 8 thousands that's .008 you want them moveable but no slack if that makes sense you may go a bit lower 7 or 6 thousands. not real sure on a stock bike mine has a stage 1 cam so my tolerances are different.
Once you have completed the adjustment hold the little square and tighten the 10mm nut back up being careful to not move the bolt it will change your gap, the best thing to do is leave the feeler in place until you have tightened one rocker the do the same for the other 3. put it all back together start the bike up let it run for a min and ride it for about 10 min pretty hard not real hard but don't putz around. on your last run back to your work area open it up just before you stop shut it down don't pull in the clutch until it stops running. pull the plug check it and see if it's the right color, your looking for a medium beige like coffee with creamer. to light = to much air too dark= too much fuel.
Setting the pilotscrew on the carb is easy turn it all the way in until it just does seat then counting your turns rotate it out 2 1/2 turns that is the factory setting. Start the bike for 3000-8000 feet turn it back in 1/2 turn if your not above 3000 feet elevation your fine. the factory main jet is a 122 for below 5000 feet and a 118 for 3000 - 8000 feet above after you get which ever setting you need turn the idle down until it sounds like a nice low tone not just before cutting off though after that turn the pilot screw out 1/4 turn more and leave it alone. put in a new sparkplug and ride it agian for a bit pretty hard agian. shut it down the same way and check the plug.. I know this sounds like alot but it's all really simple. let me know what you come up with. than I will send you what i feel will help you out the best. Good Luck
