Burman B52 moving backwards
Posted: Sun Apr 14, 2024 8:34 pm
As part of my prep for the IJR Luxembourg I've been going over the Matchless. I posted on the IJR 2024 thread about adjusting chains. I went for a shortish run out, 10-12 miles, earlier this afternoon just to be sure that all was well.
On return I noticed that the gear change had got clonky and thought about the primary being possibly being too tight. On inspection it was really quite tight despite me leaving it in a very slightly slack position as, from experience, I anticipated a little backwards movement.
I recall that the instructions I remember on this job included easing the bottom pivot nuts and retightening them but I never do this as there's no way to get to them With the AMC box in place I used to use both the "between the engine plates" mechanism and a version of the Burman set up but then back in the day I was pulling a sidecar.
I also. having used the Search and seeing a pic from Spriddler, realise that I fitted the adjuster in the right place but with the positions reversed but don't see how that would make a difference although I will swap round so the two adjusting nuts are at the rear and not the front, as I have them. Perhaps the torsion/compression factor makes a difference.
