The title says it all. I got talked into working on a TY 80 for a friend. If anyone could help me out with this information I'd be much obliged. It's the trials model with 25 mm forks. Jay

I used ATF. Kids were at upper end of weight range for the TY80, 80 lbs or so.

will check the qty in mynotes this weekend.

Matt at Speed & Sport is pretty big into TY80s.

I'll have to scare one up for my daughter in a few years... hope I can find one then.

Better have a fat wallet. This thing is a real piece of doo doo, and I had to go through the engine, carb and ignition to get it to run properly. The guy has spent around $700.00 with me just to make this dog poop bike run right.

I'm not going to but THAT bike.

actually I've seen big price drop in the TY80 about 5 years back when enough modern kid bikes got into the used chain. The small ones with auto clutch work better than the PW50, and the larger are more capable trials bikes than the TY. Wonderful little bikes, tough, but time and technology marches on. If I was doing it now, I'd start them on the Oset electrics, then move to modern with clutch.

Ebay has good ones for 400-700 total. ratty ones 200 or so.

I had two for kids, in those days there was waiting list in the club for whose kid will outgrow the next TY80.

I bought first one about 1996 from a paper ad, patchwork paint 'overhauled' (which meant rings and paint enough to sell it), I think $600. And that winter I had to do main bearings, bore, and general OH.

After trying a dozen ads to get one for second kid, always gone before I called, a friend gave me an ad phoned into the paper before it hit the streets. Grab it quick, $500. Pay and load the van. Leanred not to 'pick it up tomorrow'. When I called the seller next day, he sai he'd had over a dozen calls. and I would believe that .

Then, about 5 years back, prices dropped a lot. Ended up selling #1, with the rebuilt crank and bored and fixed, new tires, at $500.

Kekpt the second one to teach other kids to ride.

My younger two that learned on these TY are now 18 & 20, son wins Expert class. I, alas, have moved up one class since then.

Overall, well worth the investment in my kids.

Any chance you kept the one?

Hi,the fork oil should be 85cc per leg and anything between 10W&30W should be OK.

I think my customer/friend was living in the past when he bought this bike. If he had known this bike would require so much money spent to make it even close to decent he would never have bought it. I am sure you couldn't sell this bike for $700.00 ever. I hope his son appreciates his refurbished vintage trials bike, but I bet he would have been better off with a Beta or Gas Gas mini trialer. One of my other pals has a TY 80 he has spent over $2000.00 on and now he won't let his kids ride it! In a way I don't blame him but it's so ridiculous given that it was his original intent to let the kids ride the thing. It's a cautionary tale to the guy who thinks he's gonna' get a "real good deal" on some worn out junker and "fix it up". PS, thanks for the info!
