Last fall I swapped my stock carbs out for a set of 30mm OKO's. I had 25 pilots and 330 mains on the stock carbs with the setup listed below. When I put the OKO's on I put 55 pilots , needle at the fourth spot from the top, and 165 mains in and it wouldn't start without choke below 70 degrees, but with the stock carbs it was good to around 40 degrees. Now, I put 18cc domes, 50/50 mix of premium and 113 octane, and a set of Shearers and it doesn't hardly start with the choke on in a 65 degree building. I took it for a couple minute ride and it feels like it is hesitating for fuel in the midrange. I would just put bigger jets in, but people with similar setup have pilots in the 40's and mains in the 140's to 150's. I'm stumped and don't understand how there can be that big of a difference. Not sure if it matters but I'm around 1000ft of elevation. Any suggestions or opinions would be great.
