PWK Carb Tuning

[Nut]

Does any one know a good starting point to tune a Keihin PWK 39mm carb on a 89 Quadzilla? I bought one off ebay and I am looking for all the starting point settings(main jet, pilot jet, air screw, etc.). The quad is bored .90 over, has Boyesen reeds, UNI air filter in the stock air box, FMF pipe and silencer, and a Ricky Stator stator. Thanks in advance for any help.

I ran a 185 Main and a 52/55 piolet Jet. Turn the air screw 1 1/4 to 1 1/2 out. I ran this at Sea-level. If You are at a higher altitude go down 1 or 2 Main and Piolet Jets.

if you end up buying a few different jet sizes start rich and lean it out. if you're ricyh or lean wide open then its ur main jet. pilot jet is mid/bottom. needle setting is alot for idle, at least on my pwk it helps for for kickin my bike over.

Thanks Ned and 369DuneBunny. I just got the chance to take it apart and it had a 155 main, 55 pilot, the needle clip set on the second ring up, and the air screw turned out 1 1/4. It was not that far off. I had no idea what the person that I got it from had done to it and I wanted to make sure. Thanks again

369Dunebunny, I see your from Indiana, we try to go to Silver Lake once a month. Next trip 8-16/17. Maybe I'll see you out there sometime.
