This is something you can try if you are running rich or have poor mileage and you can’t seem to solve the problem no matter what you do. It isn’t meant to take the place of a proper float level, correct jetting, and a well sealed system. This will not solve problems caused by running the wrong grade of gas or lugging the motor. It is simply meant to be an additional tool. It has been done on enough bikes to make me believe that everyone should just go ahead and do it.
Basically cutting a washer shaped piece off the end. After cutting that piece off the knob it was still going in tight against the stop so more trimming seemed to be in order because I wanted to know my choke was really all the way off. The rest of the slices were much thinner. I would cut a slice and push in the choke. I did this until the knob stopped going in but there was a small gap (About the thickness of a business card) between the knob and the stop. (See note 1) With a gap between the knob and the stop I know the plunger is seated completely in the carb. It does not affect how far out the knob will go so you still have full choke if you need it and the midpoint clicks are all still there too. The knob is still firmly attached to the bar so it doesn't appear trimming the knob has weakened it. That is really all there is to it. I put a piece of white paper behind the cable so it would show up better in the pics. All the work was done with the carb on the bike and the cable connected to the carb. All I did was take the cable out of the bracket. Note 1. The round rubber stop is adjustable by turning it in or out. It is used to set the tension on the cable. Turning it clockwise will increase the tension on the cable and move the stop in. Turning it either way will affect how soon the knob hits the stop. So have it set to where you like it before you begin the trim. Questions should be asked in our forum (Use discuss link below).
