Twinshock

Never owned anything that's needed things like cases and forks etc polishing. What's the form on getting a good finish, send them off to a pro, buy an Ebay polishing kit for my bench grinder or hours spent with Solvol Autosol? .....or easy clean ali' coloured powder coating...my local powder coaters do a very good fake ali finish.

Returning to this site after long time,but same bike lingers in same barn, Norman B4/Villiers 8e moded somewhat. What I need is a running proper trials bike. My nostalgic favourites appear to be Montesa Cota 247, or as I never got to buy one in the day,a Fantic 200,though I have not ridden one of these. My local French club keep asking when will i roll . I've seen latter for not a lot of money, any opinions? Thanks.

Hey all, I have just acquired a early 80's Merlin and need some engine parts. Namely a piston kit and possible con rod kit. - anyone know of a supplier? - should these bikes have a chrome bore? It is a very early bike. #7 off the production line I believe.

After a long lay off I've come back to trials and realised that at 40 years of age club level expert route is doable just not enjoyable for me (some sections a bit dodgy for my age!!) where I am from the expert class is a big jump up from Clubman so riding a modern bike at Clubman level isn't very challenging, I've bought a very nice Fantic 240 to ride at clubman level so trying to get it as competitive as possible, what's the best rear shocks on the market and where can I get them from?

...because I have always had a real softspot for them, always found them a good looking bike , have always liked Suzuki engineering and owned more than a few zooks...I like to add one to my fleet, look good sitting beside my GSXR-750WN. ...but looking at prices over the last few months tbey seem to be bit of a bargain compared to other twinshocks....what dont I know? There always used to be a fair few doing the rounds in Kent back the day...Cliffe Marshes etc.

Hi All New to this site and to trials so Hi to all, anyhow my mate is doing up a Fantic but me being me I've gone and bought a 242 to restore and making a few calls have found out that this bike may be hard to find parts. I'm just dismatiling it at present so not sure what I'm after, if you know what I mean. many thanks for any input. Andy.

Looking for anyone that can remember or rode one of the original 230 4 speed Ossa Pennines (plonker) I alway's wanted an early all fibre glass Pennine, been hunting for 8 or 9 years anyway 2 years ago found one up near Penrith thrown in the back of a shed in one H--- of a state anyway large lump of heavys' changed hands put remains of said bike in back of van and set off for the 150 mile drive home (plenty of time to work out how i'm going to explain what a good investment it is to the other half) It was painted in austin allego metalic green and everything else in matt black (spray can).The engine unit was held together with a large hose clip round outer cover's an…

Which do people recommend ??

Has anyone had any luck with the cheaper levers on eBay? Or are they a waist of money ??

Just thought I'd drop a quick line here to thank the guys at In-Motion. Was having issues trying to source the correct cable for my Cota 247C. Was on the phone for 20 mins today whilst the poor guy at In-Motion went thru the possible cable Montesa permutations (lots!) and even went and got a bagged up cable up to measure the free cable for me, on the one we thought should fit, may not of been correct, he wasn't to know before opening it. Great service and thanks PS...now if you guys could open a well priced Trade Motor Factors near Diss with '30 minute vans' I'd be in heaven...

I've dragged the old units out the spares box and wonder if anyone can recall what pressure they should be pumped to. I did read somewhere that 200 psi was the figure but that seems more like that for air spring units and i certainly don't think my local Fox dealer had the equipment to pump or measure to that sort of pressure when he set them. I may have had a manual but that will be long gone. Any advice appreciated.

Montesa 247C with Amal mk2 Concentric. Now the bike starts n rides fine but for this odd issue. Even when hot, stop the bike, restart after say a minute and ride off, just off idle and she dies after 10 yards....keep the gas up for say 30 secs longer and ride her on just off idle and she gets thru this and is ok again and will be...until stopped again. It's annoying as it means I either keep her running in the queue for a section or restart her and give her some beans before the section to get over this 'blip'....not good if you have any mechanical sympathy. Now from what I read Amals can be a little quirky. My thoughts are she is running slightly weak…

Been offered a Cota 247 1978......up on its toes, easy starter, good compression and running ok, sound clutch, no dragging....tidy but unrestored. I could trial this bike next weekend....if ya fussy yes you would strip n tart her up. I've had a short ride on flat grass and feels small and well balanced. What is the form on these old war horses? I know nothing about them....are spares still an issue....is there the equivalent of the most fantastic 'Mr SWM' Mr Matthews behind early Cota's offering support 'n spares? Cheers guys PS my normal ride is an SWM...the Cota felt dated but quaint against the Speedy which won't be going anywhere...the Monty would …

The old boy I ride with tells me the idle mixture adjuster screw is an air screw on this Amal...yet I've always thought if the screw is engine side of the slide, it must be a fuel screw? So who is correct? Fuel screw...wind out for more fuel Air screw...wind out for more air Bike is a Montesa 247C 1978 but an Amal is an Amal I guess? cheers guys

Thought I'd post this here rather than Monty section as most t/s's run drums. Bloody odd this. Front brake creaks when applied when stationary and the lever feels spongy. The drum lining isn't split which was my first thought. Stripped the brake down and still does it...bit of a strange one? When moving the brake works ok but is still spongy. Any ideas welcome no matter how bizzare

would of said "you lucky people"..... found this whilst browsing, thought I'd bookmarked it, then lost it and took me hours to find it again. A 'Which Bike' test of the 1978 Monty 247 which I now know was called the 247C, the 'C' standing for competition. So it must be suitable for trials I guess cota 1.pdf

Hi After reading so much on this subject am I correct in thinking if I was to run my 1980 349 on one of the following popular full & semi Synthetics I would be ball park ok? Castrol Power 1 full synthetic at 50: 1 Castrol A747 semi synthetic (with Castor) at 40:1 My preference would be to go semi for the standing time protection it has over a full Synthetic on internals but am I reading into things to much? Anyone ran either of the above long term and would like to give the benefit of their experiences? Advice please Thanks

Sorry double post

Well I've got to say im surprised, i posted a request for info on the Elstar trial bike a while ago, over 700 views but not a thing, usually the combined knowledge of the forum can come up with something. Thers a good article about the bike on the BSA Otter site if anyones interested, and if you have one of these bikes or know anything about them I'd be very intrested in hearing from you

Not many of these to see these days but I have one that is misbehaving. Practicing a few weeks ago I lost the ability to shift gears. Didn't get banged. Lever resisting up a down movement on the spring but no selection. Thought the problem would be the locknut on the eccentric cam coming loose. But not the problem. Have stripped the mechanism in the primary case. Nothing seized and no broken springs. Moving through the range of adjustment allows a setting that will allow going up the box or down but not both. All gears select easily using the square 8mm peg. Timing marks lining up correctly. No noises from gearbox so I think it's the mechanism in the primary case. Any tri…
