Aircooled Monoshocks

Hi all. Just wondering what year they stopped making twinshocks and started making aircooled mono's. Or did the 2 types overlap for a while?

Hello guys, i have a Ty 250 mono and i need some tyre suggestions, im on Pirelli MT43 and it is slightly outdated and really used up, Any suggestions are a big help, Thanks

Hello there, I cut a small piece out of the back of the box for a look-see and it is a real mess of packed solid gunge and carbon. I've seen the very helpful pics from Searay175 on 03/11/16 (attached) but can't quite figure out the best place to cut the rear end of the box. There doesn't seem to be a lot of space to cut between the outlet and the mounting bracket like he did and it looks like that would be a real pain to weld up again. Any words of wisdom would be greatly appreciated.

Hi ! Anyone ever fit an alloy swingarm wheel & Disc to a TY mono from another bike, it seems it would be a great mod. The early gas-gas look similar ? Mine is a drum brake 84-87 TY250 Mono red frame. With a normal pinging motor ....PWK28 on the way from an yz85

The rear wheel on my skywalker has a broken hub. Does anyone know of a similar wheel that i could use. The rear is disc type. I have been told a gas gas may fit but not sure what one. Can anyone help.

Hi All I have a TY250 Mono ( 1985) that has the original foot rests...As they look a bit small and battered I would like to know if there are any replacement pegs that could be used? Looking where the originals are mounted..it seems even if i cut them off, there s minimal space on which to weld after market hangers... Just looking to see if anyone out there has done any mods??? Thanks

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…

My little project that has kept me busy over summer - cheers.

When running, I've oil dripping from gear change shaft, easy fix or engine split ? Ty250s

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?

Rescued a dumped JCM in poor condition and I thought I'd have a go at restoring it as in the main it's all there. Can't seem to find a lot of info on it though and my first problem is where will I get a flywheel puller for it? Thought my TY one would fit but it's a different thread. Any info on bike much appreciated. Cheers! Previous rescued & restored bikes to a useable condition and current projects.... TYZ.... Yamaha TY125 & TY250 (Pinky).... Suzuki Beamish RL250 (in pieces at the mo).... JCM (to be stripped)...

Just got an 86 ty250r and had the top end off for a look. It's not bad but has some scratches. It's got a piston with 50 stamped on the crown. Also has a shaped crown rather than even curves. Only have ordinary vernier calipers so only measred the bore at the very top. Seems to be 68mm there. Can anyone tell from any of this whether it's already been rebored. Does the 50 mean 0.5 oversize? Also any one know if Birketts will still do the 270 kit & shorten the inlet tract? Last posts i've seen were about 4 or 5 years ago. Cheers.

My son has just bought a JCM 1985 kickstart missing just the knuckle left what would fit is this the GasGas air cooled engine model?

Picked up a 1986 Honda TLM200R to provide a back up to the TLR. The chassis appears good but the motor needs work. I have searched for a supplier of parts books but found nothing. Does anyone have a copy either as a file that can be emailed or a paper copy? Happy to pay for postage and copying costs. Regards, Peter.

Hi All, Anyone know anything about air valves on the top of my mono forks? They appear to be the same size as tyre valves. I assume they are meant for loading etc. A pal of mine says they may be majesty. Any ideas chaps?

Hi Folks, Just bought two yamaha ty 250 mono of unknown age. Bikes were bought as non running but complete. both 59N chassis id One has a steel tank with a white frame (poss originally red) it has J. Shirt on the flywheel cover and silencer, the steering lock has been cut down on that bike The other bike has a plastic tank, red frame with a dirt ground out rear link (flat where it faces rear tyre) There are differences in the frames with the red frame bike having a couple of brackets with holes on a down tube at kickstart side, the white frame bike does not have that. I could put all the best bits on one bike and keep the other for spares. I…
