Muffler mounting R75/5
Re: Muffler mounting R75/5
The left axle sits just under the muffler as you describe. The right muffler bracket lines up perfectly. The left shock absorber mounting bolt lines up in the middle of the muffler and prevents the muffler bracket holes from lining up with the threaded mounting holes on the sun frame. My swingarm is aligned perfectly so I don’t see a way that I can effectively move the shock bolt the extra 1/2” that is needed to get the mounting holes to line up.

Re: Muffler mounting R75/5
Okay, stupid question, are these the mufflers that were on it originally and did they fit then?
Is the left header pipe bent? is it parallel to the right? Have you tired reassembling the headers and crossover.
I am sorry, I just can't see the solution. More pictures might help? St.

Re: Muffler mounting R75/5
I am looking at the picture you have of the pipe behind the foot peg. I am not familiar with the way the pipe bends up and it looks like the muffler is slipped onto the pipe differently than I am familiar with, a red flag.
The second picture of the muffler and the axle is another red flag in my mind, Most of the mufflers I have seen have an indent where the axle can slide out without removing the muffler. I don't see this on this muffler?
I don't see anything wrong with the shock mount or the bolt you are using.
So, are these the correct mufflers for this bike? From what I can see no, or the header pipes are not the right ones.
Someone with a R75/5 will have to chime in and send pictures of their bike's mufflers. Sorry I can't say more, St.

Re: Muffler mounting R75/5
At least you are able to get things lined up and together. I don't know if you could bend the pipe back or not? Really if you don't have to, things are together don't worry, just ride. St.

Re: Muffler mounting R75/5
I think those are not stock mufflers. I have a '71 R75/5 with the original stock mufflers. From your photos they appear quite different. Some photos of mine are below. Aside from the fact that mine are still dirty are several weeks of riding, the bends to accommodate the axel and shocks on mine arrear to be absent on yours.
