Aircooled Monoshocks

Does anyone remember seeing a picture of a monoshock Ossa in the motorcycle news back in the mid '80's. I think is was a prototype that never made it into production. I'm sure it was designated a '303'. I'd like to see the picture again if anyone has it.

I have a 92 pinky mono, the rim on the rear wheel is badly corroded on the inside, as Z spokes are hard to get I want to get another wheel but with traditional spokes. Talon have their own TY hubs(using trad spokes) and could build a wheel for me, the problem is that they are unsure if it would fit the pinky. Are TY wheels interchangeable regardless of whether it's an old TY hub or a new pinky hub? thanks.

I've spotted this JCM for sale on Ebay and was considering bidding for it.It needs work , but at the right price ?? http://cgi.ebay.co.uk/JCM-pre-Gas-Gas-350c...1QQcmdZViewItem Does anyone know any history on this company and these bikes and are there any spares floating around and if so where?. Thanks

I bought an 87' model Garelli 323 aircooled mono today, road registered on a "E" reg and only 3 owners from new and even had the original handbook with it. It's in exceptional condition, but isn't sparking?? I think the points need looking at?? i haven't messed with points for about 15 years?? any one care to refresh my memory on the right way to set them up??? And any info on these garellis would be a great help.

Hello new to ty's just got a 86 ty 250 mono with a couple of problems but one i can not work out when you rev the engine revs pick up slowly and throtling off revs die down gradually over 2 or 3 seconds .Have checked reeds and there is no gap, and carb slide is working opening and closing fine the cables not trapped any ideas ? thanks Adrian

Could do with some help identifying my 250 mono it has a nickle plated frame ,the disc break has a talon caliper

can anyone help me with this? when i apply the front brake sometimes the lever comes right back to the grip other times its fine? when i apply the front brake fully the disc moves slightly sideways? this is the point where the brake lever pulls all the way to the handlebar grip! also it moves slightly when pushed and pulled by hand as in floating? the bolts that secure the disc dont tighten fully right down so theres slight play in the disc bolt mounting holes is this normal? thanks for your replys in advance! Scotty

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 …

are they all the same? (alloy types!) do the later pinky ones fit the early ty250r bikes?

can anyone give me the air screw setting for the above bike. it is running very rich (sooty plug) and does not start very wel.. i also does not want to rev out (not good when half way up hill) any help appreciated. andyh

Besides the obvious disc brake, graphics and I think rear spokes is there much differenc between the TY mono with red frame and plastic tank and a Pinky. Not fussed on the TY with a steel tank. Thanks in advance

After the recent topic on the monoshock Ossa I thought I'de give a heads up. Just got my copy of VMX and featured inside in full technicolour is the monoshock Cheney Ossa.

Hey All , Got a project coming coming my way from my Buddy's ( whose passed away ) Son , to get the Ol' girl running again . Apparently needs a kick start shaft for starters ( no pun intended ) . Couple questions . Wasn't that a 1987 model and where might be the best source here in the States ? Any worthy mods anyone might be aware of ? Cheers ,

I know theres been a lot of praise for the above bike inc pinky! but what are your veiws on this model heading for future classic status , and will they ever really be worth everything? bearing in mind there is still lots of them about?

Hi guys, Im having a problem with my 250 yamaha pinky! when say in first gear and doing a tight turn(when throttle control is needed most!) the bike feels uneven ,snatchy, ive cleaned out the carb and jets but noticed 1, the needle at the tip is worn 2, is there supposed to be some sort of surge baffle where the main jet sits (there isnt one on my bike!) it revs fine as it should do at all other throttle openings! thanks in advance!

just purchased a 1988 txr and wondered if anyone knows where to get spares. cheers

hi i allready own a beta but on sat im picking up a honda i think its a 200 2 stroke mono shock can any body tell me what model it is looked at tlr but seems to be twin shock its old but was riding it on sunday and its very good for its age it has the tank and seat unit all in one and is blue and white not paying a lot for it cheers

Anyone here know the correct oil capacity of a pinky fork ?

Now this has probably been debated on here many times but i seriously would appreciate the advice. Some of the local "Classic" clubs dont seem to cater for or want the pre 65 bikes so as they have an air cooled mono class thought i might try that seeing as i'm an old fat git with very little talent so the modern trials are not my cup of cocoa. Seems to come down to TY250 mono, Beta TR34, Fantic 301/303 i've seen a Montesa 309 and a Gas Gas but spares might be a problem. TY250 is probably the favourite as good parts availability and bullet proof but are they competitive against the Beta or the Fantic? Seem to remember they could hold their own in the early 80's but i …
