Aircooled Monoshocks

A few pics of my pinky, non std tank and non std colour rear guard and seat unit (never did like the 'pink' colour scheme!!)

I`ve had a pinky for a while and when I bought it had a number plate with a reg but no V5. The seller said it came with a spare mudgaurd on but couldnt remember for sure. As I`ve just sold my roadbike and could do with switching my insurance policy to keep my no claims ticking over I would like to apply for the V5 but is this likely to cause problems. Anyone know of a way of checking the reg with the frame numbers to see if they match. I`ve ran a vehicle check with dvla and it comes back as a 91 yam but thats all.

Hi, I'm thinking of having my Pinky shock serviced, can any one recommend someone here in the UK ? Thanks.

My TK carb is just worn out on my Yamaha mono TY. I'm looking into replacing it with the old stand bye, the Mikuni VM26. I had read that Jon S. had success with these. Does anyone know the starting point jetting specs for a Mikuni VM26 for a bone stock Pinky? Thank you for your help.

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. Your bike will be ridden and appraised by none other than Magical Mick Andrews and hopefully Nigel Birkett and the words and pictures will feature in Classic Dirt Bike Magazine. That is assuming we can get enough variety of bikes to test. So if you have a Air Cooled Gas Gas, Beta, Aprillia, Ty Yamaha, Montesa, Honda, Merlin etc etc etc please please pm me and i will try to collate everybodys details and arrange things. I do let myself in for things LO…

Just wondering what ratio people run ty 250 monos on? Manual says 50:1 or 80:1 depending on brand. Also I was thinking of running fully synthetic if there's any advantages?

Does anyone here nows how I can get a promonty exhaust for my TY 250 ? I send a mail to promonty, but no answer.... tytrials offers some, but they want 249 for it, I found that a little bit to expensive.....

Having just spoken to birckett motorsports about a knock on my ty250mono it now apears it could be down to a blocked middle box.I wonded how do you go about cutting it open and has anyone done this and the knock and had good results. cheers peter.

My garelli rear silencer always had a rattle coming from the inside, so now i've rebuilt the engine i thought i should sort the silencer out??? So i've carefully cut the back off the box with an ultra slim cutting disc, and when i opened it up WOW WHAT THE HELL???? inside its got a pipe coming from the front of the box about 4" long going through a plate and then another 3 plates with small openings alternating at the top and bottom and the last plate has a short perferated pipe going out the back??? it seems quite a restrictive design to me, i was thinking about removing the plates and modifiying it to like a modern design with one long perferated pipe and packing a…

Anyone know if there is a place (preferably in the USA) that can rebuild a mono shock, shock absorber? Thanks, Jim

Hi , just finished the Ilkley Classic trial, which has 85 miles of road work , on my 1990 gas gas 325 air cooled mono . When I was on the road and inbetween sections and stood up the riding position is very uncomfortable because I have to put too much weight on my arms and the only way to take weight off is to ride with bent knees but I find this impossble to maintain for any distance , anybody got any cures? Nick

I have a TY250 that I planed on doing a disk brake conversion on, so today a buy a complete 1988 Beta Tr34 with a dead motoplat[no spark] was going to take the wheels and brakes off of it but i get to lookin at this bike and it is in really decent shape, as good as my TY anyways. i start thinkin maybe I should get a stator for this bike and ride it. I guess I could always find another front wheel for the TY. Had a beta Techno and it was a nice bike but Ive never ridden the tr34. Anyone else ride a TR34?

Can you help i have an old jcm 323 trial bike with the TI engine fitted. the clutch is slipping and not able to ride out of 3rd gear, as the bike is one of the first 35 bikes made it has a different clutch fitted the friction plates are more like a rear sprocket than a friction plate, there is a sureflex make on the plate but unable to find a listing for the bike or engine, have contacted them and no answer... have spoken to Joel in france but have no parts left and no part no. I think the bike has been run on car engine oil which has a slip agent in it so will mess up the best friction plates in the world. So have been messing around with spacers on the spring new spri…

Yamaha TY 250 mono on ebay item no 260361410268. Anyone know anything about these, also mention of a new exhaust system coming out ?? Sorry I can't do link it doesn't work .

Are there anny specialist dealers for AC mono parts in Europe? i am looking for specific parts for a Fantic 305. Just mounting new footrests was a lot off work as i am trying to keep it as close to original spec as is posible. So this means no welding to reposition the footrests and as litle modern parts as posible. Personly i am a strong believer in keeping a classic original, i think that is part off the classic trialsport.
