Sorry Colin, miles off the mark, this is on the mainshaft sleve, the mainshaft is what needs to be longer for the twins. Mainshaft sleve is the same length on the twins and singles

By the way, there are 2 different thickness spacers available, they were fitted to the Redditch bikes. I can't remember the sizes off hand! This might help with chain alignment. REgards, Mark

Thanks Mark, that explains why I had alignment problems when I fitted the Indian motor into the 53 frame

you can use one of these







but this is for a single chain, so you will have to adapt it to the duplex chain.



alternatively you can use a straight steel ruler thats long enough to bridge the two sprockets.

in both cases you will have to remove the rear primary cover, to get a good view on the alignment.



the spacer should sit more or less flush with the rear of the clutch center.

Thanks mauri but the problem I had was a bit bigger than an alignment tool, I was also fitting an Indian QD rear wheel in an English swing arm."the spacer should sit more or less flush with the rear of the clutch center". not sure what you mean by this, what spacer are you talking about?

Hi BigPete,
I fitted one as my clutch centre was being pushed onto the mainshaft due to the soft material. In theory you should machine the clutch centre by the thickness of this spacer, but my chain was not perfectly aligned beforehand so took the opportunity to correct this at the same time. This was about a year ago and no problems since.

I think Norm is getting confused with the larger spacer fitted on the mainshaft sleeve so with the greatest of respect, please ignore his suggestions on this occasion.

Sorry my bad, I just fit a circlip on the mainshaft to prevent the basket going on too far, but then I often have to space the engine sprocket out to get it lined up

And there is a good reason for using a circlip, you can remove it easily when you have to remove the inner primary
