Your going to want larger jets than that runnining straight pipes.I have 142 mains and 42 pilots on mine with the pod filters and drilled out MAC pipes I also have 2 shims under the needles.Your going to need screw in.Here is the link for the mains http://www.motorcyclecarbs.com/Keihin_Main_Jet_99101-393_C78.cfm?Page=2 and here is the link for the pilots http://www.motorcyclecarbs.com/Keihin_Pilot_Jet_N424-22_C82.cfm .
As far as what size I have read from old threads of guys using 150 and 155 but you may have to try a few to get the combo that best suits your bike.And as far as doing it the best way I can tell you is to search thru some of the old threads there is atleast one that really explains it in detail and helped me out is is better than I could do. Good luck.

Yes you need 2 each on the jets and I think the shims come in either half dozen or full dozen.

yes you need to remove the cover on the bottom of the carbs and you'll see the jets. And then you need to take off the top dome cover and the needle goes down through the slide/diaphram.Leave the rear cyl./carb boot attached to the cylinder and the front one attached to the carb.leave the throttle cable attached take them out the right side of the bike and rest them on the foot peg.And all this is much easier with the tank off and the air box plenium removed.

That's basicly the idea the needles will look different but you just add the shims under the head of the needle.
