I don't think that's unusual.

We just used to cut some sheet alloy to suit when shimming the 348 to take Renthals.

You need one that senses the pulses in the HT lead. The one pictured needs sight of a rotating flywheel. The small ones (matchbox size) from China last about a fortnight. I got one of these but it only lasted a few goes https://www.machinemart.co.uk/p/draper-automotive-tachometer/ I do find the speed can vary during an event and it does rise when the fan comes on. As a by the by, if you find it hard to adapt to the fast tickover you could lower the gearing. I went to 9 teeth on the front but that's a bit cruel to the chain so went up two teeth on the rear instead when replacement time came round and find that a good compromise on my 250 (I'm not one for using the clutch all the time). When I briefly rode a 260, although the gearing is the same as the standard 250, it felt to run a bit slower as if the gearing was lower - I can't explain that.

I got a pitbike seat for a fiver at the scrappy to use on my 4RT. You should be able to rig up something similar.

I only recall it being pictured, with some details, in the trials column of the Motor Cycle but can't remember hearing anything further of it, so can't say who rode it or how well (no doubt somebody can). Memory was stirred during discussion about the Emme which a pal had just seen in the Neckarsulm museum. Emme

That'll be it, thanks.

Can anyone remember who made that Bantam engined bike that used the frame as the exhaust pipe? Probably in the late Sixties.

That was them.

A couple of years or so ago there was an American outfit (can't recall the name) producing plain coloured trousers of a more seemly cut for the mature rider but I am not sure what material was involved. Are they still on the go?

Beta don't even have a book measurement for ignition timing, so are unlikely to see squish as an important piece of information.

£40 more than just the seals sounds infeasible, but £200 to change seals is somewhat OTT I would have thought. I would expect RYP website to have a video but Sherco owners may give more detail.

I don't know how you would get in touch with him but John Rushworth (presumably still resident in Scotland and still in possession of one of these bikes) might help. I know he had some involvement in trail riding so a search on such websites might produce his info.

Not so easy to modernise the steering head angle on a Greeves?

The bead of a tyre can't be stretched - it can be permanently distorted if brutality is employed. So the answer to your question is, do the job properly and it can be done as often as you like. I always turn them but find the trailing edge never heals and stays rounded ? so turn once only, though I will admit to more than once on occasion. I did once use a Stanley knife to recut (ok, I know that's agin the rules) a crossply but it wasn't worth the effort.

Being a "trials scrambler" must give it some rarity value?

Do it once and mark the flywheel so you can use a strobe in future.

Try "Classifieds" at the top of the home page.

Probably a bit too old for a "Pre'65" bike then?

Seconded!

Where could you possibly fit the pump and the plumbing/wiring? Can't see any benefit. Bound to be a more costly setup than a standard pump I would have thought. Are you having problems?

Just let it be known at trials that you're selling - word of mouth can work surprisingly well.

Get the bike supported firmly on a box below the sump then test for play by moving the fork ends by hand. Easier with a pal sitting on the bike to prevent it moving and he can feel for play at the bearing.

As far as I recall the UKR was just a "standard" Cota with a stripe on the petrol tank.

It looks like you are not taking the normal precaution of applying grease to the walls of the airbox to trap dust?
