PWK Stryker tuning

[trickedcarbine]

I have a buddy with a blaster that is fairly built and he has a pwk for the new motor. The bike is a stroker with head and port work and it has all the supporting goodies to go along with it. I have never tuned a stryker series carb and was just looking for a little info on the intracacies of the stryker carb. I started the bike with a 55 pilot and it was hella rich, so I bumped it back to a 50 and it is still way rich. After looking around I have saw some bikes that have pilots down in the mid 30's to low 40's. I also found that the mains are typicaly lower on strykers compared to its standard pwk cousin. Any one know why a stryker jets so much differently then the regular pwk?It was just so weird and almost felt like I was gonna under jet by going under 50 on the pilot. Any kehin gurus got some handy tips or hints for tinkering with these carbs?

From what I understand the air striker produces a stronger vacuum signal due to the channels in the inlet bell. More signal pulls more fuel and requires a smaller jet.

 

I tried a single 35mm air striker on my ported 350 at 4000ft elevation and couldn't get it to idle correctly using the smallest pilot that's available. It was close but still too rich.

 

I would bring the pilot down until the motor is happy and idles well, don't worry too much what size you end up with.
