Thanks mate. My only point of reference for the right sound is You Tube recordings of TYs in action, and they all kind of sound like mine. The SM silencer is really neat and I'm sure is 'quiet'. Perhaps the issue is the central box. Look forward to any other opinions out there. Cheers. (Sorry about the bike upside down shot. Got nothing to do with being down under, it's just how it turns out! Doght!)

G'day, Just got my restored TY running. It has a new Sammy Miller's alloy silencer, but it's running too loud for my liking. They advised that repacking (more packing) could be detrimental to performance. They make 'em so I guess they're right, but I imagine there's always another view. Anyone have any thoughts on this, or advice on how to quieten the exhaust overall. I burnt out all the carbon/crud from the pipe/middle section before re-installing, so that part of the equation should be fine. Is it worth getting the middle sectioin opened up and packed, or does this harm performance, too? Just thinking about all the options. Even considered that exhaust wrapping tape, but think it could do more harm than good. I appreciate that TY's do make a 2-stroke racket, but I ride in buit up areas where some quite stealth is kind of needed. Any feedback on the matter would be appreciated. Thanks. Cheers, bird

welcome freebird from bird. this links to some 350 manuals that share similar engine mounts (I believe) and other components with the 250. hope it helps. http://www.custgp.com/downloads.html

Thanks for the tips guys. I searched the wider web for info and seems you can fit a tubeless tyre with a tube on a tubeless rim. But can't fit a tubeless tyre with a tube (or not) on a non-tubeless rim. ??!!?? I think the spokes and rim shape have a lot do with it; not creating an air tight seal, or something like that. Cheers.

One last tyre question, please: Do tubeless tyres work on the TY250R, ie, the new Michelin Trial Light? Cheers.

Thanks David, I'll have to have a sniff around. Imagine the Michelins will cost more than the IRCs. There's a joint on ebay offering Pirelli here in Bris, but I think they're more trials block style for trail bikes rather than true trials tyres. Eddie. No idea about a price, but if you search ebay UK they pop up there sometimes. Also, there is no rear disk brake on the air cooled monos, though the later Z model with water cooled motor had disks front and rear. Cheers guys.

Thanks guys. Ah, um, eer, the tyres went to the dump after I had to hacksaw them off they were so rock hard! So sorry, can't tell you exactly. Trial Competition rings a bell, and they had tubes, but I don't know the exact model description. Whatever was around in 1991 I guess. See you're in Gladstone, feetupfun. Who's good for tyres in Qld/ Brissy? Cheers.

After some advise on new tyres, please. My bike had the original Michelins, but they're stuffed. Should I stick with Michelin? Any other brands worth considering (Pirelli, Dunlop, IRC...) or to be avoided? The bike is not for competition, purely recreational, but I still want it to ride right. Appreciate any words of wisdom. Thanks. bird bris. au.

Agree, one over-engineered brake there. And a lot of braking power for a trials bike going super slow most places. My Pinky has a disk up front and I wonder whether the factory went more for fashion over function at the time. Means I don't have Z spokes up front, so that a plus!

http://classicsecosse.wordpress.com/yamaha-ty-250r/ There's a shot of a TY with Talon rear disk set-up on this site. Might be useful.

250R Pinky tank is plastic. No new ones around. Most old tanks like mine have the petrol staining and cannot be painted (to last). Steel tanks can at least be prettied up with a coat of paint. But being steel they ding a lot easier. All depends what you need I guess. Good luck with your search

You're welcome.

Hey, mine was pretty bad inside too, though no huge pieces fell out, But boy it is loud so suspect there is no baffling (that wadding stuff) inside. Read somewhere that they can be cut open, carefully, from the side facing into the frame and can be repacked with the baffling stuff or repaired, if you no longer has any 'guts' inside, and then re-welded closed again. I haven't done the cutting open thing yet as I have a new silencer which I hope will solve the noise issue once my bike is back on the road. Maybe ask a local exhaust making place if there's one nearby. If you're chasing a silencer I got mine from Sammy Miller Products in the UK and it is a beautiful thing. Good luck.
