Aircooled Monoshocks

I am thinking of building something a bit different, How far can you go? is the only criteria air cooled motor or is like the twinshock can of worms?? I am thinking of modern frame with c90 honda power (or lack of it) may try a little 80 gas gas or beta,

What is the standard ( front and rear ) sprocket on a 44h TY Mono? The only parts list I find are for 350 cc model, are the sprockets the same on 250 and 350 early Mono? And If anyone would share there experience with different size I would apreciate. Thank you in advance Guy

just looking about for a mono swm or some parts for them??johnnyb

On the verge of locating and (hopefully) purchasing a 2nd plastic tank. Anybody own one of Paul @ Shedworks tank shelters for a ty250 mono? IMO they look great, but... Questions; How easy is it to remove for servicing the air filter? Do you remove the shelter and the tank stays in place each time? Or is the rear tank bolt not fitted and the whole thing pivots up at the front? How strong is it? ie can you sit on it, resting, in between sections? Any other opinions? Thanks in advance.

Hi what is the best castor based 2t oil and the easiest to get hold of? and what ratio to run it at on my tlm200 (aircooled) p.s i want to get the the castrol r smell but i have read that its not got for trials bikes cause it clogges up the piston or something like that? thanks sam

Some purists might be outraged by such a project. Normally I too find engine swaps to be a distasteful subject, but... after several years trying to keep from doing this, I just came home from work one day and started in on it. I guess the winter weather has effected my judgement. The front subframe has been welded together out of alloy strap material from the hardware store, and short chunks of renthall handlebar. It's very satisfying to be able to make something like that, finally having a tig welder to play with. The project has a long way to go, but should prove to be a fun ride and a great conversation starter. Also perhaps a handy excuse for lackluster finishes i…

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 an enquiry about preparation of Honda Tlm200 and Tlm220 motorcycles for Trials on the Honda Forum but no response so far. http://www.trialscentral.com/forums/topic/54936-tlm200-and-tlm220-preparation-for-trials/ Can anybody on this Forum provide advice? Gracias Esteve

Given the value/ prices TLR 250 twinshocks have been achieving recently I was wondering what the rare mono RG model would be worth. The white one with blue and red stripe. Completeley different bike and quite rare. I have been offered one that requires a couple of small jobs sorting. Possibly more of a trail bike maybe. Any ideas, or any users trialing one on here. Thanks.

So how many folks know anything about this 1986 Honda air cooled 244 cc 4 stroke, six speed box monoshock bike? My pages are here:- http://john.rushworth.com/pics/tlr250r-g/ I'm curious about how many were made and where they are? I guess there are about 40 now in the UK. I've yet to see and hear for sure if there is a 1987 H model too. She weighs about the same as an RTL, which I've ridden. Mine is far more forgiving though and a joy to ride. The torque curve is sooo flat. Great! I have a history from Ian Smith's Motorcycle Reports on TLs's and RTL300s etc including and out of interest Shinja Kazama's ride on a TL230R up Everest in 1983 to the southern column of Pumo …

finally got around to testing my newly rebuilt beta,the rear suspension seems too hard,do i just back off the pre load untill it feels right or is there a more scientific method ?

I've just bought my lad an old ('82ish) Suzuki TS125ER to learn on The main prob is getting spares We currently need - in no particular order Kick start (then we can get it running) Both side panels (we were quoted nearly

Hello It's wonderful to join you all I have a tx 240 but the disc valve came loose and jammed, I would say it's a catastrophic engine failure as the flywheel slipped, crank gears slipped, disc valve broke in 2. Flywheel previously welded on and crank taper is in bad shape. Cylinder and piston are fine and bearings all ok Where would I start looking to get a rotax 240 engine to replace my old one or part to fix her. I bought a rotax 122 engine but it would require some fabrication to work- drive sprocket won't fit its too low for the chain. We're worried about the strength of the frame if we start cutting. What alternative engines are the…

Hi, does anyone know a good jetting starting point(main+pilot) for 26mm PWK f/side carby for a TY250 mono, Ta.

Hi, I'm considering a 1985 jap import TY 250 Mono, just wondering what peoples thoughts are on these, any pros cons or things tor look out for? This has the autolube fitted, is this system easily removable, being an import are their any specification changes to be aware / wary of? Cheers!

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

Hi Can any one tell me can you still get the stainless Pro Monty exhausts for the TY. I have a number and E mail but have had no luck in getting an answer so far.

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

Hi All Looking for some advise please...MY 1985 TY 250 Mono starts ok and would run ok, however, it keeps "hunting" and pinging once it gets hot...I have decoked the piston and exhaust, and even fitted a Mikuni carb to see if that makes any difference, but the same thing happens with the Mikuni as it does with the original Yam carb.. I've done all the other usual stuff like new plug and made sure both carbs are clean and using fresh fuel.. Does anyone have any ideas What I can try next?
