Aircooled Monoshocks

  1. Started by kimpybugalugs,

    I'm thinking of going the aircooled mono route. I'd like - 2 stroke, disc brakes at both ends, electronic ignition, not too exotic so that spares are available. Which is best? I've seen a Montesa 310 and a Fantic 305 for sale but don't know anything about either of them. Any info appreciated? I've also seen a Honda TLM220R - this only has disc on front - do later ones have F & R discs. My thinking is that I can ride the air cooled mono class at the "classic trials" and have a go at "modern trials" on the same bike. Any info/advice greatly accepted.

    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

    Hi all, I have recently had a TY Mono fully rebuilt (engine) but whilst it runs "ok", comparing it to a friends on Sunday who has recently bought one the engine goes appear more flat. Now that I know the engine itself is 100%, I want to explore the front exhaust (the rear has been replaced with a new box) and also the carb, so questions: 1) I have a brand new Mikuni VM26. Has anyone tried one of these and do they have a starting point for jetting (slide, needle etc) 2) Are replacement front exhausts available or is it a "cut it open and weld it up" affair? thanks, any advice appreciated....

    I have just collected my latest toy a JCM Vega which looks very original but has not run for a very long time judgeing by the state of the tyres. Any hints and tips on how to set up modify them? I think it has the 330 engine but need to lift the head to be sure.

  9. 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.

    Hi all Anyone know the torq setting for the front sprocket nut? I have online ty350 manual which covers most of what i need for my 250, but no reference to the front sprocket at all?! It does have a table of torq settings based on nut size, but it only goes up to 20mm and that’s 130Nm!! thanks

  11. Im restoring this 1986 GasGas 325 Halley at the moment and Ive run into a problem. The rear wheel around the bearing is cracked beyond repair. Weld would simply break at this stress point and in any case the metal does even take weld, particularly well. Welding is out of the question. It is a Nagesti 120mm internal diameter drum rear hub. Nagesti were absorbed into Akront. Merlins were fitted with 110mm Nagesti's so this is not good enough. Does anyone have any knowledge of other bikes that this rear hub was fitted to ? Thanks in advance

    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…

    I posted a topic in yamaha forum asking if anyone knew where I could get the extended arm type clutch lightener for my TY250 but no joy, thought I would try posting it in aircooled mono forum as it seems to get a wider audience. A couple of people suggested making one but I don't have access to metal working equipment. I am sure that someone somewhere must be still make these in a little workshop as so many bikes seem to have them (except mine!) I have just finished restoring my TY back to it's former glory which I posted in the Yamaha forum recently and am looking for the clutch lightener to further improve the riding experience, and my skills!! Any help / contacts …
