need help on jeting pwk28

[Fleker8]

hi, I'm new with the banshee, it was running great with the old stock carbs and tors system, but I removed and put a pwk28 and eliminate the tors, and airbox. banshee only starts with choke on , and when I close the choke it turns off, so I think I need another main and pilot jet, my setup is:

- motor stock, bore 64.25 mm. NO port job

- cool head pro design 21 cc domes

- vito's reed valves

- pwk 28mm 29S, I think they sell it with , mian jet: 135 , slow jet: 38, needle: 46JJH, Thr. valve: C.A. 3.5 ( I don't know about this last value)

- UNI straight POD filter 5"

 

Location

-What is your elevation? 

 12 ft

- What temperature is your Banshee jetted for?

weather is around , 86º-122º farenheit

humidity around 30%'

need to know what range of main jet and pilot jet I need to start to play with?

 

THANKS

you have nipples on the top of each carb that need caps installed to eliminate the vacuum leak.

I know I'm a little late but I ran 28mm PWKs for 1 year back in 2012. They are supposed to be great on woods bikes but I could never get them dialed in right and there was almost no jetting support for them. I went back to stockers and have run them ever since There are more jetting guides than you can shake a stick at.
