Is he still around? I had the impression he'd shuffled off.

I'd have thought that getting rid of the ton of slack should go a long way to reducing the clutch drag.

I look forward to many stories of trials and tribulations....

The Brightspark external magneto capacitor seems to work very well and it's tiny.......

I'd be looking at blocked main / needle jet to start with, but could easily be a magneto issue. Could also be poor fuel flow - blocked tap etc.

They do indeed have an excellent forum: The club is very good.

A couple of other useful links: have huge quantities of used spares; Christian's archive at has all the manuals etc you could ever need.

Those forks are easy enough to strip. That's what I would do just in case there's a broken spring (or sprong if you prefer) or the like in there.

There are some 250RS enthusiasts here: - may be worth asking?

What the PRV normally does is to prevent excess oil pressure getting to the bearings etc, especially with cold thick oil. Usually what happens is that the valve is forced off its seat against spring pressure, and what comes out (which would be oil) generally gets sprayed around the timing gears etc. It's normal for the valve to lift under normal circumstances but obviously not all the time.... And clearly it shouldn't come out of the joint you mention. Maybe a breathing problem?

Have you had a delve in Christian's archive which has everything anybody ever wanted to know about AMCs?

The AMC forum is good as well although I think you need to join the club to get full access.

I thought you decided against the Triumph?

Are you sure the return side of the oil pump (actually I seem to remember that the AMC twins had 2 pumps) is working? There should be no more than oil mist in that area. I don't know the engine in detail but oil pressure release valves usually open to allow excess pressure back into the timing cover so you may be on to something there.

Did you get this instead of the Triumph? Much nicer bike IMO.

Now you can look for a proper bike!

If you could get it for say 2,000 or less it might be worth a punt. I had one for a short while but it wasn't really my cup of Assam.

That could be a good price. However.....

I never understand why people put bikes up for sale with "minor" problems. Being of a suspicious turn of mind I can't see why, if all it needed was a battery, the owner wouldn't fit one and increase its sale price by 1,000 or thereabouts as it would then be a runner.

I must confess to having fallen for this sort of thing myself in the past......

Keep us posted. And keep the hands and fingers out of the way!

We're about back where we started.

A thin cutting disc in an angle grinder may get between the coils of the springs to cut through the central shaft. Then remove the top part through the hole in the frame lug, lever the bottom section complete with slider up till the rod clears the hole in the bottom lug and you should be able to - very carefully - slide the whole lot sideways to release it. But beware the spring tension.

If you can't get the cutting disc between the coils then you'll have to cut the spring as well.

You asked earlier where you could get parts made and I pm'd you a possibility. I now understand you're in Australia so as that source is in the UK probably not suitable. But don't you Aussies have a reputation for making stuff by melting old saucepans on the barbie?

There must be small machining shops in Melbourne. Here's one:

Here's a spring manufacturer:
