    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.

    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 ,

    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.

    take a look at this on ebay item no. 150022974895

  16. 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 …

    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 …
