Carb jetting question

[SP33]

I have a 1995 SXI with the dual Keihin carbs. My engine was build by Tim at Zforce using a stock SXR 800 cylinder that has been ported. I have installed a Factory Dry Pipe. Anyone know what new Main Jet and Pilot jets I should use? Thanks.

Ask tim, He'll get you damn close if not perfect on the first try.

Unrelated but did you have your head milled? I have a 750 head in perfect shape milled by tim to run 175psi on a ported 800 I dont need anymore. I switched to a ADA this year.

He milled a head for me. Thanks though.

If they are the 2 jet Keihins you will have to start with the Factory Spec for the Dry pipe. You will most likely need to go up on Both the Highs and Lows.
1995 750SXi
Main jet : 135 front, 132.5 rear
Pilot Jet : Stock 75
High speed screw : 1/2 turn out from closed
Low speed screw : Stock
Needle: Stock
Spring: Stock (cut spring to lower to 18-20 psi) Notes: Stock compression and timing

Thanks everyone. Tim got back with me today. He is working on the jetting and getting back with me.
