Twinshock

Hi All, I'm getting my 1971 Cota 247 ready for the upcoming vintage season, and I've got an oil leak that is driving me crazy. Both the gearbox and clutch drain plugs just refuse to seal (the 2 large flat head screws on the very bottom of the engine). I've tried fiber washers, aluminum washers, and rubber o-rings, with no joy. The fiber and aluminum washers continued to leak, and the o-ring just pushed out from under the head of the screw. The leaks are slow, just a small puddle after a day or two, but with no way to check the level, I have to change the oil before each ride. Any suggestions?

Can someone please point me towards some TY175 Tank Decals of the red white checkered variety, there's normally some on Ebay but sods law as soon as you want some there not there!!!!!

Just resurecting one of my ty175's and have just purchaced some new falcon shocks and the sammy miller footpegs, although i'm not aiming to create a museum piece I do want her to be competetive in the twin shock class. I have noticed that one of my 175 frames has been modified, although cruedly to enable the rear shocks to be layed down to a variety of positions. Is it worth swapping frames and if so what is the ideal distance from the original top mount to adjust the shock too? What are the advantages/disadvantages of laying down the shocks and at what angle do you stop?

I have decided to replace the AMAL 627 on my 76 MAR and go with the Mikuni VM Carb mod, what I would like assistance with is has anyone out there done this mod and what size Carb did they use and what size Jets did they select. The other question that I have is what setup was used for mounting to the Barrel and to the Airbox. Any and all assistance and recommendations will be greatly appreciated. Cheers Glen

Can you get progresive springs to fit older Falcon shocks? I have tried ringing Falcon but never any answer? will Betors new progresive spring fit ok?

Looking for some new rear shockees for my TY175, here in Aus I can't find any importers so I'm having to look further afield. Can anyone recommend a reliable dealer as i've emailed Sammy Miller a coulple of times with no response perhaps no one wants my money?????? What shocks do you recommend guys? Thanks Austini

I am trying to get my Montesa Cota 350 clutch to work perfectly...ha ha. The clutch drags when it is cold so the cable has to be tightened too much. When the bike is hot, the clutch works good and the cable can be loosened a little. Sadly, I have a bit of experience with the Montesa clutches but I

there's been a couple of threads on this in the past, but need a couple of seats (one SWM, one Honda) recovered, plain black is fine. Any recommendations in the UK (ie fast and reliable) that people have used recently ?

I've just been looking at a clip of an indoor trial from Italy, the minder/catcher was raised on a forklift truck, to his position, looked at least 15ft from the ground. This got me thinking 'well that's a bit dangerous'. Arena Trials have lots of sharp edges and hard floors, wasn't there a Japanese rider who broke both wrists a couple of years ago. The sections seem to get more and more dangerous as the years progress, is it that the promoters have to forfill the publics need for more and more excitement. What worries me, is our up and coming stars, i'd hate to see them, risking themselves for the sake of entertainment and possibly risking the real goal of world champio…

Sorry to carp on about this subject again guys but has anyone fitted the front exhaust pipe from SM yet and if so does it fit ok? ive got a full alloy WES system ready to go on! i understand ill need the front ex,flange? where can i get one of these from as i dont want to saw up my majesty exhaust system as its still good(but heavy!) dont want to waste

Hi guys, Has anyone fitted fork springs from another bike, say ossa or bultaco? as the fork springs on my ty250 are ******, just pushing the bike forward makes them sack right out! i want to keep it standard'ish and not mess about trying to make other front ends fit etc! any ideas?

A very dear friend of mine who unfortunatly is nearing the end cards made this little tank/seat unit for his ccm, I think it improves an already awsome piece of trials machinary, what do you think?

Just had the hubs and brake plates blasted for a Majesty I,m building. Need some advice as to what primer and paint to use to finish them with, before rebuilding the wheels. Thanks

Hi Guys, New to this forum - have posted introduction elsewhere - although glad to see its not compulsory! A couple of quick questions that some of the Montesa experts might be able to answer: I am re-building a Cota 247 bought as non-runner on ebay (will I ever learn!) So far its been fun, havn't rebuilt a bike in 15 years (last bike rebuilt was a Guzzi) Its a right bitsa with frame no 21M16407 and engine no in the 5000s and a tank/seat unit from late 70s version. OK, questions: 1) Would the fact that Frame is 1974, engine 1972 and they don't match make getting a V5 harder if I was to try? 2) When does the vintage no-tax deal start - 1973, 1974, 1975 - would thi…

Hi to all... Wonder if anyone can help me, my friend has just bought an ossa gripper 350 1981 and is in the process of restoring it and is badly in need of complete front section of the exhaust, we would appreciate any help on this as its a diffucult part to source.. thank u

Does anyone have an idea of what the top end play on the small end of the crank should be for a 349 or later version 348?? I am trying to get the adjustment right with different size the thrust washers but am not sure what the minimum should be??

Heres my majesty 250 isnt she a beauty? enjoy!!!

thanks to woody for his advice,the mods are now complete. 1. footrests repositioned. 2. swinging arm length increased by 40mm 3. shock absorbers 25mm longer. 4. forks pushed thru` yokes 10mm 5. handlebar clamps repositioned up and forwards 20mm took the bike to bracken rocks today and happily it is much better,seems to grip and turn in great,the biggest improvement is the riding position,feels more like a modern bike.

On the verge of getting some BPS shocks for my TLR anyone got their own veiws on them, who uses them?

in the middle of rebuilding a monty 348,does it matter what side you split and leave all the internals in?cheers
