Vintage BMW Motorcycle Owners

I would contact David Woodburn if you don't want to do it yourself. I can't find his contact info, but Vech can tell you.

Well, if nothing is binding and everything is assembled correctly (a lot of ifs) then maybe the throttle assembly is worn out. Have you removed the twist grip and cam for inspection? Good pictures of what they should look like can be seen here: https://vintagebeemerparts.com/ and in Duane's article....
