Am running a 3" BDL on the 120 Ultima. The bike has a slight urge to drive when clutch is disengaged. Am I able to get this adjustment out of the clutch itself or is it best to get the adjustment out of the cable??

Don't have much experience with the open primary.

 

You probably need to rebuild the clutch.. New outer steel pins and plates. I'd also pull the clutch and check the splines on the inner hub.

 

Re-adjust both. If it's a bdl it's a different adjustment than a stock clutch. Bdl clutched only need to be a 1/4-1/2 turn out.

 

Adjustment procedure here.
