If you read my other post, you are up to speed if not, Ill recap. I played with the rotational setting of the TPS on the carb. I found that if you rotated it back and fourth with the engine running, it effected timing at idle. My conclusion is this, if you have access to good (race) gas, you want to play with this setting. I found that if I rotated the TPS counter clockwise about 2-3 minutes on the face of a clock, the idle rose significantly. This is the location that I left it at. Highest idle speed. After resetting the TPS I needed to readjust the idle back down a tad. I also decided to play with the mixture screw. I found that if I leaned the mix, it idled smoother, and revved cleaner. So I did that too. Result: Bike pulls cleanly off the bottom with solid predictability, was easier to start, and was crisper through out the entire range. I also found that a little popping on decel would go away when the bike was fully up to temp. This wouldnt be the case prior to the TPS adjustment and the same mixture setting on the pilot. I believe the reason for the popping is an artificially high idle, caused by insufficient advance timing at idle, disallow the lower throttle setting at idle. With the ignition timing just slight advanced, you can reduce the throttle opening for the same idle speed, and thusly reduce the fuel, because the throttle setting is lower allowing less air, and actualy a higher vaccum pulling as much or more fuel at the same RPM, becaue of the lower throttle setting. If you want to try this mod, go for it, its easy, and you can always put it right back, if your TPS is marked properly. I dont know if you could do this with pump gas. I run 100 octane unleaded. IF your running pump gas, doing this mod may produce detonation, but I have the feeling that it might not be all that harsh, and it may be no big deal. But use a careful ear anyway. If you have access to race gas and run it, do this mod, your bike will be quite a bit smoother. Final settings were as follows: Pilot 45, 3/4 turn on the screw Needle: stock 2000, #3 postion Main: 168 200 feet above sealevel (Saddleback) 85 degress 74% humidity. Im stoked, and Im leavin it!
