Without thinking about it, I hooked up the Tuneboy and noticed my TPS reading was .635 volts. I had just adjusted it before my last successful dyno work for $175.00 worth of time.lol
Bike was running good. I readjusted it to read the .6 volts + or - .05. Keep in mind that I just got off work in the early morning and just started playing out of boredom. Bike was cold and I didn't even start it. Now I seem rich on the low end. Trying to figure out what I did wrong for it to move, I decided to read the manual.duh.

I guess it would help to warm up the bike and set the idle first with it at operating temperature. I'm going to warm it up and reset it again and see how it runs. If it feels like it did, I'm set. If it doesn't, I guess I need to go back to the dyno this weekend and recheck the AF with the right setting.
Hey, these manuals are really helpful if we use them.

Setting the TPS to a voltage at closed throttle can be dodgy because differing bikes might need the idle adjustment at slightly different settings to tick over (especially if you've bored your TB's). If you have access to a TuneBoy, go WOT without the engine running and read the TPS measurement, it should be 94.9% if the TPS is set correctly.
