Throttle linkage

[Dick B in KY]

I have just started my phase 1 (Supersport with 912ULS) and am finding that the McFarland dual throttle linkage is trying to bind and stick in place after the friction lock has been tightened and then loosened. Has anyone else had these symptoms and what was your solution? Linkage says not to lubricate at friction nut.

Thanks,

Maybe take it apart and clean it thoroughly. I'd use isopropyl alcohol.

I recently replaced my throttle system with the macfarland unit, and I love it. Before I laid out the cash, I called the company and asked a few questions regarding their product. they were extremely helpful. I would suggest that you call them directly and ask for their opinion of to remedy the problem. I bet you will be impressed with them.

what is a macpharland unit? A picture would surely help...

Sorry, what I should have said was "McFarland dual throttle linkage ". I believe that what I installed was the same as the one in question, but the point of my reply was that the company was very customer friendly, I would start my troubleshooting with a call to them.

It's the dual cable throttle handle sold by several suppliers.

I couldn't get that Link to work, so here's one to the manufacturers page...

Contacted the manufacturer, very nice tech rep. Getting a new friction nut packing kit and new springs for the Rotax carbs-not as strong as original so don't have to tighten friction nut as tight. We'll see how this all works out.

I took the return springs off of the carbs on my 912. The throttle cables are thick enough to move the carb linkages with no issues. I barely have to use the friction nut. Since there are no springs it stays where you put it with just a little tightening. I think there are several people on here that took them off as well.

I want to change out the old style Vernier in my model 4 w/912 to McFarland's Vernier-Assist Throttle Control. Can someone save me a trip to the hanger and difinitively advise which control length is required? Thanks much.
