I gota say, my SWM 320 1980 std bar 10mm on the arm was THE best clutch of any trials bike I've owned, modern or old. I rode a new 1982 back in the day and that was fine too. Just had new proper cable, proper Domino leavers and perches, steels roughed up with 80 grit, running ATF, set up correctly.....and greased balls oooer.

PS I do wonder why trials shocks have gas over oil...it's not what I would call a heavy duty cycle?

Wow, I've never seen a C clip to retain a rear shock. Cool idea. I took the shocks off to grease up the mounts & fter looking at my shocks closely they are actually quite new, they have 504B on the bottom of them? Compared to the gas Betors on my SWM, they are a little oversprung for my weight. These shocks are all black and oil only, no gas, possibly NJB Clubmans? I'll give the boys a call tomorrow. Thanks for your help guys

Hi Andy, a bit late to the party but hey, so what. I've the same bike, a 247C (Competition) and they are lovely bikes, light, small with a very friendly and smooth engine. The early ones from June 1978 had front fork spring air assist whereby you could pump a little air into the front end to firm them up. This feature was soon deleted though, as they couldn't get the air to remain in the forks.....sounds familiar to modern MX boys Mine is heading for a rebuild in week or so, only for a frame repaint as the tank paintwork is still original and they are only original once. PS Your air filter is correct.

Maybe of some help to someone https://www.motorcycle-manual.com/montesa/

Cheers

Hi guys, want some new shocks for my 247C Can anyone provide what length and mounting dimensions I require? Many thanks for your help.

Well, Speedy has gone off to pastures new. I'd like to thank all on here whom have helped in the past when I've had queries or needed helped, when I was but a rookie SWM owner and not the Uber Anorak Owner I later became. Martin at Moto SWM needs thanking too, like Dave at BikeTech GasGas it's great when someones business is also their passion. Honestly getting parts was far easier than for my late Yamaha WRF's I've owned....chatting with some bored and spotty 16 year, who grunts when distracted from the smartphone is not a fantastic experience I'd like to share. cheers guys, all the best

thanks guys

My 247C has quite a few false neutrals. Yesterday at tthe trial the old boys running newer stuff, were fondly remembering that even when new, these Montys's came with some free neutrals kindly donated by Montesa. Is there a fix, or a case of "they all do that sir" Bless the old girl, she really shone on the loose, sandy hill climbs, such a soft 'n friendly engine but grunty when needed, love this bike. yeah I know, no 6th!

Soooooo glad I did the clutch spring mod', when we run the modern mono's the sections around there are getting so tight it's really tough for twin shocks - well it is with my limited ability), you simply can't 'ride' the sections without a lot of clutch work at some point, or ya looking at fives. Saying that I may lower my gearing, she's on OE gearing and this seems a tad fast? My Speedy has been lower to the point whereby 1st is almost redundant but great for the tight 'n tough stuff, and I can change gear in the section without getting a box full of neutrals.

cheers guys, These are known as AMC Lightweights, yes?

't other side, now that's a clutch cover!

Yup, and a backhoe on the rear end, there's a lot of tin work to hack off it for sure...should lighten it by half a ton....not sure where the other half would from come though? But it has a certain charm, there are few things to wonder and enthuse over. For example, I like the rubber pads on the tank, to stop me bashing my legs when I fall off, that is forward thinking, even Beta REVS don't have this cutting edge safety feature.

Betors work fine for me on my Speedy with the caveat of the correct spring rate...If I had I gold plated factory Ohlins front and rear I'd still the same crap rider. I've NJB's on my 247 and they are stiff as fence posts...need correct springs, previous owner was a fuller figured fellow. Those in the hopping 'n jumping Red Route experts like a Rock Shock around these parts, but I think they could have angle iron rear end and still be competitive...thinking of a Bantam hard tail rider

The 'throw' on the levers is all wrong too. Had dreadful problems with my SWM until I fitted Domino OE's. ....avoid!

....the word fugly was invented for this bike.

Theres is a Matchless G5 for sale locally, the erm 'lightweight' series.... Anyone trialed one, or even know anything about them? I could just use it as a roadbike if it's a complete non-starter...in the trials sense. Bit of a curio thing, pudding basin, goggles , white scarf 'n glass of milk. 1960 350cc single....the fake unit engine one...you know, the one with big bulbous engine cases...similar (same as, bar name tags!) AJS model 8. Or a G2 250cc with 350 AJS 8 engine if you wish.

Scratch the ATF....in this hot weather and a long trial the ATF is getting too hot. My bike when hot has a noise as the clutch plates go finally fully home...sort of a rattley grrrup noise which is worse on ATF Using 10/40 engine now and seems better. PS anti rattle springs in place.

What bike is it?

Wow....if Carlsberg did answers to polishing case's thanks for that

You must of seen me ride My SWM has a really light clutch..it's an early one too without the additional lever under the tank. All springs fitted. Standard plates. Runs new cable biggest difference was using the correct Domino perches and levers. Actuator arm has been lengthened 10mm.
