jetting for short body PWK.....

[haugergaard]

Hello!
first post for me here on gasgasrider. I bought a 2009 Nambotin a few weeks ago and it seems to have the short body PWK. Anyone found any nice jetting setups for winter riding with this carb. Preferrably with slide 7????

Read that this carb needs to be jetted leaner than the pwk found on earlier models? Is your experience with the carb i am talking about? Or am i wrong in thinking this is a different carb???? Suposed to be longer from carb to reeds....

the carb has 2 screws holding the lid on and its shorter frt to rear the jetting i use runs great also use this jetting in my 03 and my sons 06 if youre around 1200 feet it should work. my 09 has the short carb u have

Great, i will try to get ahold of the cek needle. The linear motor carakter is what i am looking for, thanxs.

Finally got it tested. Had to go 42 on the pilot, because it was fourstroking 1/4 to 1/2 throttle. 0 celsius, 800-1000 feet. Linear power across the rpm range. Just what i was looking for
