Aircooled Monoshocks

Hi Can any one tell me can you still get the stainless Pro Monty exhausts for the TY. I have a number and E mail but have had no luck in getting an answer so far.

I did a bit of trials in the 80's on 70's twinshocks as they were all I could afford at the time and I've not ridden trials since but have done plenty of green laning and the odd enduro. I realise that a very modern bike would probably be the best bet for ease of use but I have no desire to own one.......I just like aircooled traditional looking bikes so will stick with twinshock or aircooled mono class. Would I notice much of a difference between riding an aircooled mono and a 70's/80's twinshock if both bikes were well maintained and sorted? Will I make it easier on myself with a 90's mono bike or is the overall technology between the 80's & 90's bikes not that m…

I will be possibly looking at a fantic 403 monoshock aircooled drum brakes, as a beginner could I get through a few years of trials, and ridding with the locals and maybe at my first couple of events with this bike. Or is it hard to compete with the older bikes and a waste of time and money (tight) should I save for longer and get a newer bike or if it is in good shape go for it? Do any of you compete with your bikes and do OK? Dan

Hello, So i'm looking for a spare engine for my TR35 Beta (50cc) The current engine spare parts are of Unobtainium or extreme expensive. The clutch is slightly worn out and i hope it will last some time. But i like the bike! So the idea is to run the bike for the rest of the season. And rebuild the bike this winter to twinshock & install new engine. AM6 / DERBI engine. +Lot’s of spare parts +performance upgrades. +Cost of a tuned engine quite high (70cc, good crankshaft, heavy clutch) -> 300-400€ + Engine size is quite the same, some welding required -Still a 50cc gearbox -> easy to fail -Water cooled (cost of radiator, non c…

Help! I bought a 240 JCM trials bike some time ago which appeared to work perfectly. However, I've since discovered that when the engine is hot, she's difficult, nay impossible, to start. Then when the engine cools down, she starts perfectly again. I suspect that it could be a problem with the little red box thing under the petrol tank which I think is something to do with electronic ignition perhaps??? I've thrashed her with a leafy branch, called her a few unprintable names and locked her away in solitary confinement for a few months but she still flatly refuses to behave. Any technical advice would be much appreciated. http://s605.photobucket.com/albums/tt136/b...nt…

Hi, I've just got a Mecatecno Amigo for my son and would like to know if anyone could give me any technical info such as engine type and spares availability.Thanks in advance

does any one know the gearbox oil quantity? i think the bottom end is the same as a cota 242 / 330

I was interested in a cheap montesa 310 (circa 1990ish), however,it has a goosed ignition system, (stator plate etc.u/s ) and according to sandifords, the motoplat parts are pretty much "unobtanium", as motoplat wint T8ts up a good number of years ago. Does anyone out there know of any suppliers of motoplat bits. Also have any of you had one of these bikes, and, if so , what like are they? thanks

Having just spoken to birckett motorsports about a knock on my ty250mono it now apears it could be down to a blocked middle box.I wonded how do you go about cutting it open and has anyone done this and the knock and had good results. cheers peter.

Non Bikes :- who decides ? What's the criteria ? Ariel with thinly disguised betor forks - ok Belt driven diaphram clutches - ok Billet hubs & yokes - ok Replica frames - ok Twin shock a mono - ?????????

Dont quite know how i came to be involved in this one but do you have a Pre95 Air Cooled Monoshock ? We are looking for owners who would like to come along to a test day somewhere to be decided in Derbyshire on June 10th. Your bike will be ridden and appraised by none other than Magical Mick Andrews and hopefully Nigel Birkett and the words and pictures will feature in Classic Dirt Bike Magazine. That is assuming we can get enough variety of bikes to test. So if you have a Air Cooled Gas Gas, Beta, Aprillia, Ty Yamaha, Montesa, Honda, Merlin etc etc etc please please pm me and i will try to collate everybodys details and arrange things. I do let myself in for things LO…

does any one have any real good pics they could post on here of either or both of the following bikes ridden in 91/92 world championships- ALPHA ridden by Thierry Girard OR /AND ALFER ridden by Lluis Gallach and Josep Arcarons. from memory i saw an alfer on a trials wtc vid years ago and i am just curious to see what something really different and rare looks like bring back any memories??

This is when bikes were bikes.... and we fell off more A good shot of Eddy Lejuene on his Merlin DG 350 FIUS for 1988 - (where's his glasses?)

I have the chance to pick up one of these bikes but know nothing about this model. I seem to be missing the gap between the 349 wich I owned and the 310 wich was much more like the modern cota. Are spares easy to get? Did they send very many to the U.S.? i just picked up an old TY250r mono thats in good shape and has had many of that periods mods already done. Maybe I should pick up the cota and sell the TY. Thoughts anyone?

Anyone fitted one of those nice looking fiberglass covers on there Mono Yam??? Two things, Fit???, Quality, do they take a knockor two.

ive just got a fantic 212cc, it has a monoshock disk front brake and drum rear brake how can you find the model and year of the bike. i have changed the statement about the brakes in my haste to post i got them the wrong way round the bike is white with yellow and is the same shape as some models ive found they range from 1989 to 1992..

Hi Can anyone recommend a replacement carburettor for a 270cc TR 34 Campionato? Thanks

Hoping to run the mecatecno at a club trial this weekend. Just need a wee bit info confirmed by you knowlegable people. Engine oil capacity & type, 500cc 75w pji clutch tuner ? Plug type B8es ?. Mixture 50: 1. Any one know if rear wheel is the same as any other bikes ?. Any one know if rear guard is the same as any other bikes. Do these bikes normally sound fairly loud and ringy from the top end.

Hi All Looking for some advise please...MY 1985 TY 250 Mono starts ok and would run ok, however, it keeps "hunting" and pinging once it gets hot...I have decoked the piston and exhaust, and even fitted a Mikuni carb to see if that makes any difference, but the same thing happens with the Mikuni as it does with the original Yam carb.. I've done all the other usual stuff like new plug and made sure both carbs are clean and using fresh fuel.. Does anyone have any ideas What I can try next?

Hello Does anyone have any idea of the length of an original TY Mono side stand? Any large diagrams/pictures would help as im looking at getting one made Cheers!
