Aircooled Monoshocks

Hi, Sorry but I cant find any of the previous postings about TYR front brake improvment by using YZ shield, Will ask any of you who have done this conversion, what year(s) of YZ front shield is working with TYR front hub? Cheers,

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?

Hi all I recently rode my air cooled gas gas for the first time. I bought as a complete bike but have had to do quite a bit so far such as fitting an 18mm kickstart shaft and a pedal and clutch case to match from a JTX model. I noticed two things in the 30 mins test. 1. It gets very hot, the tail pipe is almost too hot to touch where it exits the middle box so i wonder if the timing is retarded too far. I seem to remember they kicked back a lot but this doesn't. The second issue is the bike has quite a flat spot at 1/4 to 1/2 throttle, this may also be timing related but the bike has a noticeable induction noise. The filter box is the proper one but the lid has been d…

Hi, I am having some issues setting up this air cooled mono, its recently had a full engine rebuild, I have cleaned out all the exhaust system and repacked it, i have had barrel off for inspection and this would appear to be correct, i have stripped the carb down and to be honest its very clean(original 26mm TK), it would run then suddenly stop...this faulted to the ht secondary ...replaced aok, i rode it 3/4 throttle up a long hill and then did a plug chop)nicebrown/tan colour(, the problem is lower down in carburation especially when warmed up, i believe the pilot maybe a tad weak, anyhow iset air screw to 2 out, and rode it around fine tuning on air and tickover then i…

can someone tell me where I can buy a set?

Hi All I need to make a tee bar for a Yamaha TY 250 mono to strip the forks does anyone know the size of the hexagonal IE to suit a for instance (19mm) socket not sure of size just guessing? Cheers Mike

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?

take a look at this on ebay item no. 150022974895

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.

Have aquired a mecatecno skywalker. Bike is running but requires rear shock rebuild. Has anyone any information relating to engine / frame parts list / etc. Also looking for a similar rear mudguard to replace broken. Any help on these bikes would be appreciated.

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?

ive just got a fantic 212cc, it has a monoshock disk front brake and drum rear brake how can you find the model and year of the bike. i have changed the statement about the brakes in my haste to post i got them the wrong way round the bike is white with yellow and is the same shape as some models ive found they range from 1989 to 1992..

Does anyone do lowering brackets for the TY mono foot pegs? I know Sammy Miller does them for the twinshock. I'm keen to avoid cutting and welding if I can. If I can't avoid cut and weld does anyone have any drawings to help fabrication?

I am currently rebuilding a JCM 240 Europa - one of the Streit models - I think 1989. I dont appear to have the correct rear brake set up. does any one have a parts diagram or photo of the correct caliper & cylinder? unit I have is a Brembo but the hose looks short, Cylinder mounting screws are 6mm - holes in frame are 8mm. any of you guys have any experience of this?

I have a Delorto PHBH26 carb which I have had from new basicaly I am thinking of off loading it and do not want to mislead any one so am looking for some advice as to how good my memory is (and if the carb is of any use) I owned a 1984 250 mono (first ones out) For some reason at this time it was the thing to do to change the carb to make the bike run better I used it for a year then sold the bike but kept the carb Is my memory correct and is this a thing anyone else remembers. I can't even remember if it was significantly any better than standard any views ??

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

It looks like all the previous TR34 owners have upgraded or broken their bikes as they have stopped asking questions! Therefore it is my turn to ask a newbie question. I've not done an oil change on my 1989 TR34 yet and I have no idea what oil to use. Reading other threads has left me bamboozled. I know I need 800cc gear oil as it states this on the Beta website. What is the best grade oil as I don't have to worry about having a Beta with a dodgy hydraulic clutch? Also I'm currently using up an old Motul 2T oil at about 70/1 with the expensive shell high octane petrol. The trusty Beta website says I should use Semi Synthetic so I was looking at either the PJ1 or Si…
