Sounds like you may have a different problem than jetting. Check for full voltage to the coils first.

Is this a street or strip bike. I'm running 29s with 17.5 pilots on a street bike with a stock 1015 engine. I get a good bit of lean popping at 1/8 throttle and below, at 1/2 to 3/4 turns out on the screws. 1/4 turn out didn't idle well.
In my way of thinking, the carbs are designed for 1 1/2 turns out on the air screws to emulsify the idle fuel mixture correctly, I'm thinking go up on the pilots until you are getting the proper volume of air moving through the idle circuits.
Not only will you have the proper A/F mixture at idle, you will have plenty of fuel flowing right off idle before the needle takes over. Am I not thinking about this the right way?

I've gotten tired of thinking about this and went out and took the carbs(29s) off my bike. Gonna try some different pilot jets and see for my self how this will work out...building a carb stand now Anyone have a Colortune they want to sell???? :whistle: :lol:
FWIW, an it may not mean anything, I screwed the air screw all the way in and backed it out to 1 1/2 turns while watching the hole in the air screw through the idle air passage. At lightly seated position you could see the top edge of the hole, at half turn out, 1/3 of the hole was visible, 1 turn out, more of the hole, until at 1 1/2 turns out the hole was lined up in the idle air port. Maybe a coincident, I only got to do it on one of the carbs.

So you should not need to turn them out as far as you would on the other carbs - I think a good starting point is about 1/4 turn from lightly seated.
