OW,
May I call you OW?
Anyway, I'm running 130 mains, stock pilots, AI gone, snorkel gone, stock air filter, Thunderbike pipes, 18t front sprocket, TBS needles with no shims, and I drilled the vent hole in my slides. I'm happy.
I should have kept notes as to the order of the mods, but I didn't. But, I had a problem with popping on decel that I just couldn't get rid of, and it was intermittent. I even had a problem with the engine "napping" if I blipped the throttle while downshifting through the gears - it would not rev if I was downshifting quickly. That is when I put the TBS needles in and those problems disappeared and the mid-range and upper end of the throttle felt stronger. I was happy.
I read the vent port drilling thread and waited quite a while before I got the nerve to try that. It made the throttle response somewhat "crisper". I am still happy.
Point is, after each mod, without a dyno available, I synched the carbs and checked the plug color and was seat-of-the-pants happy. I don't need to squeeze every last ounce of hp out of this bike to be happy. I'm at about 750 ft. above sea level, 6' tall and 185 lbs. My favorite color is black and chrome, and if I win I will promote world peace and solve world hunger.....
Do yer mods 1 at a time and see if they work for you.
Your results may vary......
