Thanks. When you refer to tangs you mean the steel plates I guess. I only noted one which was fitted on the outer to allow it to reach the outer basket. I will check them all again.

Thanks for reply. I think that is the standard spring length. I bought some new ones (surflex) that haven't been delivered yet. They are supposed to be 32mm apparently! Mine has 6 x 26mm springs in it which I suspect are off a different model. I am going to put them on our hydraulic test machine at ...

Have early MHR with 8 plate surflex clutch. Does anyone know what length the springs should be please?

Just putting my MHR back together. Which way up does the steering not go as it has a recess on one side around the central thread? Does it go against the top bearing dust cover or up against the lower of the top yoke. I can't see what difference it would make? Thanks.[/img]

It was a 33mm I/D x 3mm cross section nitrile O-ring. Find one the same size in a different material preferably but this is only on the low pressure side of the system so I will keep an eye on it. Cheers.

and then you get this....

This seems to state Nitrile is ok with glycols....

Yes interesting. I also have a Norton Commando and have just relined the front brake master cylinder with a kit a company supplies that has a nitrile washer (!) to seal it and then advises DOT 4 fluid probably out of ignorance. I am not overly concerned if I have used a nitrile 0 - ring here as it's ...

I will Steve next week. I got 4 big O-rings from work, two from a yellow box, two from a red box. I assume that one box was metric, one imperial. I now need to put the spares back to know which I used!

It was very tight but I put a little Brembo seal grease from my master cyl recon kit and it went ...

Found one to fit thanks

Does anyone know what exact size the O-ring is that fits between the plastic round fluid reservoir and the master cylinder. Mine came out and just looks/is way too big to get back in. Don't know if it changed size when I cleaned in petrol but it ain't going back in. It is approx 37mm Inside diameter ...

That's a nice set of scooters, enjoy...
Cheers

Thanks Steve, yes that's the book. Where did the last twenty years go...?

Any ideas where I can contact Fontana, couldn't find much on Google.

Thanks anyway.

Hi
Just bought an early MHR (one of first 500). I had a Hailwood 23 years ago at University and had a little red book (can't remmber author) on tuning the Dellorto's that recommended buying Fontana shocks. I bought a pair with red springs. The bike handled really well but the shocks were still very ...

I need a seat cover but can't see one on the site Steve? Does anyone make them? Also a cover for the rear pad with DUCATI on it? These are the same as the 1981 models.
