Is it running with the choke on ? Guy

i just receved yesterday the entry form for this year Vintage Fest at Ormstown Qc , and for the 3rd year Mick will be there. I look foward to meet him again, as you all said great MAN. He does'nt only advise you on riding technic, he generously give you pointers on '' setuping '' your bike. If you never attend Mick trial scool, you miss something. Guy

I think that you should stick to DT and not to DTMX or MX as those have single ring. DT 360 1st os and rings are avalable for under $100.00 US. GUy

I use to ride a TY A with the flywhell lightened, now I ride a B model with the same flywheel. I could'nt bring myself to put the super heavy B model one. Might be the right thing in mud mud mud !!! As far as the MAR, I only tried one and it was not setup for me so I did'nt like it but the owner was cleaning it sections with 2 finger in the nose I would '' 5 ''. Jon, the extra ground clearence make a lot of difference. Guy

I don't know about that. Those groove are pretty full of dirt when I take the wheel off and clean the brake. Guy

I always '' groove '' the shoe even the use one I reinstall. A picture here http://s1065.beta.photobucket.com/user/guy532/media/22012012030_zpsef88d4f0.jpg.html#/user/guy532/media/22012012030_zpsef88d4f0.jpg.html?&_suid=1358601924321016418547409440687 Guy

Here in Canada they where equiped with a starter ( from 1974 on I think ) and where heavy with a flat power band. I don't know anybody that modified one to improve it. Also agreed with twinshocktosser for there quality. Guy

depending of the way you cut and reweld, oyu can keep the same wheelbase as the original. Guy

If you plan to make the mod David did on the Peter Pace replica, think twice about the next trial you want to attend with that bike. I have acces to a machine shop and I worked in maintenance for a long time, I can tell you that it took me a lot more time than I thougt it would, and the final assembly is often not the final assembly as you have to custom fit everything. So I realy tip my hat to you David, planning and realising that bike with nothing but old photo to refer to, I don't know how you did it. I hope you enjoy riding that TY as much as I do. Guy

Hi oilmanincanada Where, in Canada, do you live ? I have a couple of TS TY and a 250 mono for witch I am looking for a 3rd os piston with no luck. Guy

I have a set ot Betor trial expert and a set of NJB ( both 340mm, 40 pound spring ) on standatd and modified TY and I like the NJB trial Expert, I should tell you that I'm an average rider, so maybe I cannot tell the difference. Guy

Hi Thats_a_five, if you look at the other picture you will see Mono and IT piston, machining a new sleeve with the exact porting is a lot of work since I only found one second OS for std 250 mono. After the holiday decision time will come so .... Guy

Fantnik : Thank's I will check Wiseco although I'm not there biggest fan and also give Mitaka a look Tony : Yes the piston pin is set close to 2 mm lower on the Mono ( probably because of the 68 mm stroke vs the IT YZ TY ts stroke is 64mm ) and the skirt of the piston is also longer on the Mono. So if someone have done the mod they had to mofify the cylinder base and the also machine the head . 2stroke4stroke : Yes I'm looking for a barrel or a complete bike for parts, but here in Québec ( Canada ) they are few, and I looked all over the net to find a piston ring set. Hopefully I will find the parts or the correct modification to do because as you can understand I can't make mistake. Guy

The bad news came this morning, I need a 3rd OS piston ( and ring ) for my 250 Mono. I didn't find one and I am told an IT ( or YZ ) or a TS piston would fit with modif made to the cylinder and head. Quite a few post are scratching the subject, but if someone as done the job with good result I would apreciate the details. Of course my first choise would be a 3rd os TY but ... I also will change the rod , but replacement is avalable. There are 2 different type of IT piston, the one with the '' arche '' is suppose to be beter but wear faster. I don't realy use the last bit of power of the bike since I am an average rider. So TS or IT and if IT, withc one choose? A couple of picure of IT VS std TY http://s1065.beta.ph...837536139540032 I should say that TS piston is not a problem to get . Guy

Thank's, I'll pass those info to a friend who is looking for a way to change the handlebar mount or to move it back on is KT he is considering using RoxRiser to do the job , I don't know if it's a goo idea. Guy

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
