Guidance Jetting From Stock To 28mm Keihins

[BluBanshee98]

Just wondering if someone could give me somewhere to start on these new carbs I bought. The bike ran sweet with the stock carbs and I was running 320 mains, 25 pilots and 1 on the needle position. I pulled the plug off the bottom of these 28 keihins and they have a 135 main in them. I am in Vegas for a elevation reference. Any help on where to start would be greatly appreciated.

I have the same carbs on a shee I just bought. I called Trinity and got their jetting specs. They sell a 28mm PWK settup, and use a 155 main, 55 pilots, and a JJH needle. He said the needle is the whole key to this settup. I ordered the whole set from them for $35. That is for sea level. I am at 1700 feet so I got 150 mains and 50 pilots.
