Aircooled Monoshocks

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…

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

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?

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

hi all just a quickie need to replace the main bearings in my ty and have found out that the part number is a 6206 c3 thing is are the bearings handed left and right or can i just buy a pair of bearings thanks

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

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!

I have a couple broken fins on a Mono cylinder, I'd like to repair them but I'm not sure if the parent material is aluminum or magnesium. I know the side covers are magnesium but not sure about the finned cylinder. If anyone knows which it is, please let me know. Thanks, Jim

does any one know the gearbox oil quantity? i think the bottom end is the same as a cota 242 / 330

Hi, I have just been looking at a Titanium Front pipe and Carbon Fibre Leg Guard combo for Gas Gas Randonne on the Mitani Website , does anybody know of any Agents in the U.K. or an easier way of getting hold of one without dealing with Mitani direct,Cheers Nick

My clutch on my mono has bad it! I'm wondering if anyone knows if the clutch plates are the same from any other yamaha models? I don't fancy paying £58 just for friction plates. Thanks Paul

Simple, thanks again to thai-ty.

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

I was interested in a cheap montesa 310 (circa 1990ish), however,it has a goosed ignition system, (stator plate etc.u/s ) and according to sandifords, the motoplat parts are pretty much "unobtanium", as motoplat wint T8ts up a good number of years ago. Does anyone out there know of any suppliers of motoplat bits. Also have any of you had one of these bikes, and, if so , what like are they? thanks

Picked up another TY350 today, loaded with spares, including an NOS std bore piston and rings! Score!!

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

Been noticing that there are a few after market shocks available for the TY250R. Rock shocks, Hagon and now even an Ohlins unit from CTC. Anyone fitted any of these and come to any conclusions on them? My original shock is okay so I'm not needing a replacement, just wondering about whether the performance is much better and what the weight saving is. Cheers Hoodie.

I am rebuilding a JCM 240 Europa from the late 80s. when I was replacing the fork seals ( I believe these should be Marzocchi ) I found the internals of the 2 forks are completely different. is this normal & does anyone have a parts diagram or any maintenance info on these forks?

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