I've been lurking for a long time and have started reassembly of my ty250A. I'm trying to order parts for the rear swingarm and can't find much information using the site's search. Has anybody had success with this kit that appears to replace the stock bushings and dustcaps with needle bearings and brass endcaps? https://www.francetrialclassic.com/en/frame/4963-yamaha-ty-125-175-250-rear-arm-bushing-kit.html I originally noticed an identical kit on ebay but the description was vague and I wasn't sure if it would fit. This seems to be the only trials specific website that lists this kit, everywhere else just carries the oem style bushings and dustcaps. …

Any leads on TY250 parts? I need a crankcase cover, kickstarter and handlebars. Much appreciated!

Have seen on some ty175 they have replaced factory starter arm with a al one! Does anyone know what they used ?

Saw that you can replace stock triple clamp (loose stile balls) bearing with new contain ball roller bearing . Was wondering if anyone has new stile roller bearing number. Thanks

Hi. I have been eyeing the WES exhaust systems, both the single unit to replace the stock silencer, the two piece mid section with separate silencer, or just the silencer I was wondering the benefits of the different systems, and other than being much lighter, are there differences internally from the OEM muffler? Does the replacement muffler noticeably quiet the system down? Is a new exhaust required as well to fit the new system? Sorry for the basic questions, but I’ve seen a lot of them fitted to TY’s but was wondering if they really made a big difference TIA! 🍻

I have managed to put a nice dent in my TY175 tank. Can anyone recommend a repair company who will also respray, fit new decals and then lacquer? If so, any ballpark of cost? UK - ideally south east. Thanks.

Hiya, I'm new to trials and bikes in general to be honest haha and have just bought my first bike, a Yamaha TY175 1981/1982 model to ride and remodel. It's a brilliant wee bike however, it is missing its side stand and I'm struggling to find the complete parts to replace. I seem to only be able to find the springs online. I don't suppose anyone knows of anywhere that could help or if anyone has a spare they would be willing to sell, or even if there is a worthy universal stand that anyone could suggest. Any ideas would be appreciated! I'm located in the UK, near Cambridge. Thank you! 😊

There might be the possibility, of a trade deal coming up... I'll wind up with a TY175 .. 74' model I believe.. I like the looks of the twin shock classics, and those tiny little seats.. Give this fat man a place to rest. Ha. Just saw a picture of a TY with modern forks and a disk brake. Yes.. watching the classic trials videos on YouTube.. Those bikes are really neat.

I would like to ask for help in 2 matters 🙂 one is what is the exact model of the carburetor? It is Mikuni 3M2 ? second, where can I get a repair kit for this carburetor 🙂?

Hi All, I am back with another question regarding the 1977 TY250 493 I am working on. I am in the process of replacing the crank seals and, I got the left hand side out with no problems, but the right hand side, the clutch side, is giving me problems. I got the crankshaft gear removed with no problems. I have to remove the clutch basket to get to the seal retainer. And I got the clutch plates removed, but I am not sure which hand thread it is on the clutch basket nut. Looking at the few threads that are exposed it looks like a left hand thread, which makes sense since the crank shaft nut was a right hand thread and these turn in the opposite direction. I have an Dewa…

Me and my friend are restoring what we believe is a 74 ty250 based on the design on the gas tank but we’re having a difficult time trying to find info on the bike. What’s the name of the engine and/or do any other bikes share an engine or parts, what’s a good place for parts or info??

Can anyone offer me advice on myTY 250 Mono 1986. It keeps fouling plugs. When I remove the plug it is dry but with thick black deposits. The bike runs well for a time but after about every 4 hours the plug is fouledand needs replacement. Is this an ignition ot carb issue? Any advice gratefully received.

Hi, I have a TY 175 Whitehawk and when I removed the head and barrel for a rebore I noticed that the head bolts had been modified and cut down as the stud holes in the barrel were a smaller diameter than the head. Does anyone know if this means I have a DT175 head or did the TY175 have different variations?
