OSSA 350 TR80 PWK Jetting

Featured Replies

Hi,

Thinking of fitting a PWK 28mm on the old Gripper. A common mod by all accounts, however I’m struggling to find the basic start jetting for these carbs. 
Does anyone know and willing to share?

I have an 28mm OKO already but I guess it’ll need jets/ slide/ needle to suit the gripper. 
TIA

Brent

 

I would have thought that 28 was a bit big, but give it a try it will probably close as is.
