Just about to fit an aftermarket set of footpegs and plates (sammy miller) but i have to squeeze a chain tensioner in there somewhere! Can anyone give me a few tips on how best to complete this task and even a few photo's etc. regards To all .

Have you a chainguard bracket fitted to the swinging arm?

I made a tensioner, copied in steel from a Scorpa and fitted it with a bush to the chainguard bracket and used a coil tension spring clipped to a small hole in the guard bracket. Works a treat!

However SM uses a TY175 tensioner on their own widened swing-arm which has a strange fit for the tensioner spring.

Nice one big John, i did look at the bracket you mentioned it's towards the swing arm end, I think it's quite a good location to start from .thanks John.

As John said TY 175 pic attached, if you need more pics let me no

This is a miller swing-arm, so it came with a mounting lug. Tensioner is from Sammy Miller, but the spring location would need improving (bit crap as standard)

My Full SM Cub has the same tensioner which works well but the SM footrests are TOO High and TOO far forward. You may want to check this once they are fitted. The height was 14" and only 75.5" from center of rest to front wheel spindle. It seems the ideal is 12" and 77-78" or you will end up with too much weight on the front end and have some interesting rides in the classic "round the tree and down the hill" sections! Having been over the front 4 times before discovering this it has been corrected and is now in the No excuses class with near perfect handling. If you lower the pegs you will also need to manufacture a rear brake stop as the SM pedal uses the engine case and is too high up for a normal foot. See my "blog" for the modifications.

Hi

I welded a couple of brackets on and used ty175 type tensioner, though the tension spring is not that good it needed some tweaking!

A big Thank you for all your photo's and advice. It has helped me out superb. keep any more pics coming please!
