Tell us more about the steering mod Guy

I'm not a specialist, but every time I can, I have a test ride on any trial bike, and my TY B and I have in mind a couple of A and D just work fine, not at par with a good SWM 350 but beter than any 250 that as not been cared for. Good clean well tune carb, CLEAN exhaust ( very important ) replace the head gasket by a thinner one ( .005 to .010 ) good piston and a sprocket combination that suit your riding style. Voila... a respectable TS. Yes you have to set up the suspension! As Andy wrote I took the flywhell weight off on my B but this winter I will put it back on ( maybe a little lighter than the one on 434 model ). But Dixie your not the first one with that impression, if you dig a bit you will find more than one thread asking your question and getiing more advise than I write in this reply. Guy

That base is not like the one on my byke. and the front sprocket is sooooo small, but if you look closely this is realy a trick trial motorcycle. Guy

On my 44H, it's clamed on the larger diameter of the tubes . If it's what you mean. Guy

No the only thing to do is to lower the brackets that hold the filter box from over the frame to under the frame. ( Mick Andrews's advise ) Guy

Right on Tony Guy

Does it pull from idle and than get's rough or is it rich right from idle, also check if the carb is clean, I bought the same carb and had the same problem to find a piece of plastic providing the choke to close correctly. Guy

What do you want to do with the bike? Guy

Big weekend of fun comming up, 4 days with Mick Andrews ( I hope the wheater will cooperate ) first thing I'll check when I come back is the size of the VM, I had both carb 5 feet apart this saterday and did'nt think of that. Guy

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

Ok this is one of the first thread I read when I bought my TY. I can tell you the clear answer : Yes it is worth the trouble. Guy

I talked to a friend who is quite aware of mod made on 2 and 4 stroke back in the days, I wanted some advise on the front pipe on my mofified TY. I wanted to cut about 3/4 inch and reweld it. The first thing he told me is: your gonna loose bottom power, so I did not touch it. Is it possible one would gain low end torque by lengthened the it ? Guy

Comming from you David, I can only think I did it right. Guy

Exhaust? probably. Air filter ? Most likely Timming? I'd surely check, but your on a Yamaha, so you will have fun. Guy Ho Lord... I sound like I have a favorite prejudice.

Yes on the bike on the left the frame was modified to increase ground clearence. That's why I have been asking so many question on modified TY frame. It's a lot of thinking, fitting but it's well worth the work. I have to thank everyone who gave me advise, some of them deserve double thank you. Guy

I ride them both, but one will have to go since there is more birds in the nest. Guy http://s1065.photobucket.com/albums/u399/guy532/?action=view&current=DSC02052.jpg

How do you post a picture? Guy

I did it last year ( a VM Mikuni ) I had to sort out the jetting. It was not easy since my TY A is not stock. But yes they fit right on. Guy

Make sure you have the right model, I order from R..Rider in the US to receve TY Mono reeds, I think if I want some Boyessen for a TY I will now order them from B&J in US. Guy

Easy , simply to make sure the bike would get top money ???????? 40 odd year later. Guy

Nice work Jon, I work mine with the frane right-side-up but the general idea is the same witch reassure me as I have no reference exept pictures and a lot of help on this and other post. I still am a little confuse with the air filter, I will probably make one so fit properly Guy

Cable Cable Cable . It seem's silly but I had the same problem I quadruple check everything untill someone mentionned the cable. When removed from the bike it look ok but it would'nt slide all the way.So I was burn one time now it's the first thing I check. Guy

I finaly found a TY Mono 250, I had a 350 a couple of years ago but could'nt pull myself to fix it ( a 350 was not what I wanted ) so I sold it for the price I had paid to someone who was locking for one. My new aquisition need some tlc but is in a fair shape, I don't want to make it a SSDT winner but a good reliable trial machine. In the serial number there is 44H so I assume it's the model, Since it's running I was able to test ride it at home and first thing that came to mind was " Am I on the second floor? " I am use to my TY A with the footrest lowered more than one inch. Now a few questions Fork oil, it says in the 350 cc manual ( the only one I could find ) 99 mm from the top of the inner tube without spring is it ok, I run premiun gas with 20% VP mix : 50:1 on my A model I plan to use the same any tought on that? I found the motor very slow on throttle I run my A without weight on the flywheel should I do the same on this Mono and I am considering putting Boyesen reeds, should I cut some web on the reed block. Any advice welcome. Guy PS I would have posted a picture, but I don't know how

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

You need that seat, it goes with the rear footrest. But it look in very good shape for a barn rescue. Guy
