Aircooled Monoshocks

I was just wondering if the only difference between the Ty250 and 350 is simply the engine size/bore? I can only get hold of a workshop manual for a 350, and wondered how relevant it was to my 250. Looks pretty much the same, but my friend said that once about a girl he met in Thailand...

hi what is the difference between the ty250 mono and the pinky version and which one would be the best to have cheers....

its a moto morini engine air cooled with manual clutch and four gears and a backwards kick, crank case inducted with a 14mm dellorto carb, does anyone know the engine model?, looked on various websites like harglo etc but nowt exact it looks like a very early one and i am worried about getting service parts etc, engine no is fgm30*000126

I bought a 44 H TY mono a few weeks back, fixed the igniton and put it in the shed while I finish a TS project, this weeckend I made a few round behind the house to find it very VERY " SLUGGISH " so I took the carb off cleaned it put it back with no improvements. I'm sure the exhaust need's a good cleane up but still I think the carb need's fixing. I have " on the shelve " a new roung slide 26 mm Mikuni ( VM type ), is it a good idea to try it on ? Or am I loosing my time, I know I have to modify the flywheel. but I have to start somewhere. Guy

This should be an interesting one to watch, hav'nt seen one up for grabs for a long long time, thought there might of been a few more quids on it. May need a few things to tidy. http://www.ebay.co.u...4.m1438.l2649

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 - ?????????

Does anyone know the offset measurements for a TY 250 Mono rear wheel (drum brake)?

Having decided to invest in an early mono to compete against the modern bikes in the intermediate class.. where should I put my money.. I fancy a Fantic 305 or the slightly more modern Aprillia climber . Having had neither back in the day, like a lot of people I had a mono yamaha , which way should I jump as I would like something a little different. If anybody has any whys or why nots please feel free... Thanks

hi can anyone let me know where to download or purchase a manual or parts diagrams for the ty250 monshock or pinky thanks

I finaly found a TY Mono 250, I had a 350 a couple of years ago but could'nt pull myself to fix it ( a 350 was not what I wanted ) so I sold it for the price I had paid to someone who was locking for one. My new aquisition need some tlc but is in a fair shape, I don't want to make it a SSDT winner but a good reliable trial machine. In the serial number there is 44H so I assume it's the model, Since it's running I was able to test ride it at home and first thing that came to mind was " Am I on the second floor? " I am use to my TY A with the footrest lowered more than one inch. Now a few questions Fork oil, it says in the 350 cc manual ( the only one I could find ) 99 mm f…

Hi, I'm thinking about lowering the foot pegs on my pinky. Is it a worth while mod bearing in mind I'm going to have to pay for the work to be done and will it detract from the value of the bike ? Cheers.

after a few weeks of fettling and a bit of investment the project my dad started about 20 years ago is finished. a friend borrowed it and rode at the bognor club bluebeards trial on saturday 2nd. he rode the harder route and only lost 1 all day. the bike ran really well and never missed a beat, i've just got the bike back and its amazing how easy it starts. i've uploaded some videos of the trial. including one of it starting from cold, really pleased that it did so well. also check out the riding shirt i found in the garage http://www.youtube.c...A?feature=watch i think its now going to be sold to make room for the next project. cheers wayne

What is the standard ( front and rear ) sprocket on a 44h TY Mono? The only parts list I find are for 350 cc model, are the sprockets the same on 250 and 350 early Mono? And If anyone would share there experience with different size I would apreciate. Thank you in advance Guy

I've been thinking about getting myself an aircooled mono to go with my garelli 323, and was wondering what is considered the best allround aircooled mono??? I might do a few mods to whatever i buy like changing the footpeg position if needed.. i bought a 91' TY250r pinky(with a modified cylinder) on the weekend but am wondering should i buy something else instead? heres a pic of the TY

i'm very slowly getting my JCM SR 240 up and running again with a view to eventually selling it, to raise funds for another project for information- i used to ride it in the early 90's and it hasnt been started since then, before my dad died he started rebuilding it , the frame was powder coated, the fibre glass tank seat cover has been repainted, new JCM piston found and installed and new stickers made, unfortunately he became ill and never finished it. its by no means immaculate but doesnt look to shabby!! its now running (thanks to a friend) and i'm going to try it out this week......very excited!!!! does anyone have any idea how much oil should be in the forks, my…

I bought an original 1986 Gas Gas Halley on tinternet. Matey said it was complete......but it wasnt, the silencer was missing I need to fabricate another one to match the original exactly. The body of the silencer will be hard anough to replicate the original . I also need to source some internal baffle pipe which i can run through the centre of the silencer. Does anyone know of a company or person selling any ? Is it available ? It would save me drilling hundreds of holes in a bit of pipe which would be pretty grim Ta
