I’ve heard good things from all of them except the Heidenau. Heidenau makes tires for older or vintage bikes and have a good reputation but not so much for their trial tires. I’m also pretty sure you’re running a tubeless tire on the back and, I believe, Heidenau only makes tube tires. If cost is an issue I’d go with the IRC because they’re much less expensive and many reports rave about them and say they do everything a trial tire needs to. That’s (IRC T-R-11) what I’m getting next. The difference between the Michelin tires and Dunlops is like spitting hairs. They all have excellent reputations. The Dunlop TL01 is their newest version. The difference between them are in how soft the tread is, weight and sidewall stiffness. The differences are minimal, however. You’ll need to decide which will work best for where you ride and style of riding. Mitas has a new version of trials tire that I’d like to try, but they’re not available near me. This new version is reputed to be a big step up from their older version. Who knows if it’s true though?

Nice looking bike!

I love all three of your beauties! Your TY looks fantastic (so does the Honda), it still has the tail and headlight on it along with the original plastics. Plus, I can see that awesome, pristine saddle you didn’t know you had. Thanks so much for the photos!

Hey Tybone, would you be willing to post a photo or two of your TY? I’d love to see it!

I’m not sure I agree with an MTB helmet so I’m putting this out there for consideration. There’s an old saying that goes like this, “Buy the best helmet you can afford!”. The reason being is that you’re playing Russian roulette with your brain. MTB helmets aren’t subject to the same testing standards as DOT helmets are. Yes, trials riding isn’t as fast as street or MX but what happens if you go down and the bike lands on your head that’s next to a tree, rock or hard pack. The shells on MTB helmets aren’t as strong as a rated helmet because MTB bikes weigh a fraction of what a motorcycle weighs.

Holy cow! You are one lucky leprechaun! That cover looks pristine. Buy a lottery ticket.

Welcome to the forum! I had a 1974 TY250 myself when I was 15. I absolutely loved that bike. I had a crash on it and was hospitalized with a concussion and when I got home from the hospital I couldn’t find my TY in the garage. My mother sold it. She kept the money from the sale too! See your other post about a seat. I sent you some options.

I don’t know if you’d be interested in this but through the following links you could put one together. The seat pan will need new foam but it would be an economical way to get an OEM looking seat. I found another link on eBay that was selling, what they claim, is an original, new seat but they want over $9000 for it. Yes, $9000 is correct.

It’s rediculous, I know. https://www.ebay.com/itm/155945452638?chn=ps&mkevt=1&mkcid=28&google_free_listing_action=view_item&srsltid=AfmBOopsjTnPTsYqxoH5moPUHu_Beh0nkNb6Akoy1cUXrgTmKqSZjDRxZ2o

Triad, below is a link to a US company that specializes in electrical components for older bikes. Not sure if it will have the right one for you, and if not, it’s still a very good source to bookmark. I believe they make everything in-house so it may be possible to get what you need built. They also have a CDI, ECU Repair Unit also. Good luck! https://www.regulatorrectifier.com/

Reghusky, I’d suggest you use an epoxy putty to fill the hole. It’s very easy to control the application. You simply cut off the amount you need and mix it with your fingers. If you use a 5 minute liquid epoxy it could run inside your carburetor and make problems worse. I inserted a link to JB Weld SteelStik that’s worked great for me and it’s formulated to work on metals. You could use the leftover to put in your toolkit in case you break something while on the trail. The other option, if you can determine the thread, is to put a screw/bolt in the hole then tighten it down. That way it can be removed easily in the future. https://www.jbweld.com/product/steelstik-epoxy-putty-stick?srsltid=AfmBOoow4TSrJyoiKEz1T--jEoSYMv0MvMKrvs4AjsApeWY9MXnM8HpG

Welcome to the forum! I found the following. Hope it helps. https://www.ebay.com/itm/204636602989

Phil, it’s very easy to replace a head gasket/o-rings. I did it for the first time and it only took about 15 minutes and I’m no mechanic. Simply unbolt the head, lift it off, clean the surfaces, place new gasket/o-rings on then bolt it back together, tightening the bolts in a criss cross pattern, little by little, until the torque requirement so you don’t bend/warp the head. I believe your bike is air cooled so you don’t need to worry about draining the coolant. I had a friend in high school years ago, who had no experience mechanically, and he replaced his head gaskets on a TY 250 with no internet or YouTube to help. It’s very straightforward. You can do it yourself for sure. Good luck!

Hey Jeff! Welcome to the forum. I just did a simple search and found several TY80 original wheels on eBay. Maybe I’m misunderstanding what you need though. Anyway, below are two links to a full rear wheel and a front. Good luck finding what you need! https://www.ebay.com/itm/256739081016?chn=ps&mkevt=1&mkcid=28&google_free_listing_action=view_item https://www.ebay.com/itm/162588017989?chn=ps&mkevt=1&mkcid=28&google_free_listing_action=view_item&srsltid=AfmBOoopomzC1tONF4ljLp0sdbSqOeiIC_rvqKKSSo1g02_aOgSIJGkJkpY

This video will show you where the oil filler port is. You have the “older” clutch cover described in the video. At least, I hope it will. https://youtu.be/SKPCCsKOgr4?si=zsZasnYuUxNHTCfD

SamAs, I don’t think I’ll be much help to you but I have a 23 TXT 250 that does NOT whine when shifting to 4th. I think the engines are nearly the same as the 2017 but I could be wrong. I’m no mechanic and there are others on here that will have better judgement than I, but I simply wanted to let you know that in my experience, on my bike, there is no whine shifting to 4th. If there was I would be worried. So far, working on my own bike, I’ve found it’s simpler than I ever imagined to do it myself. If you’re mechanically inclined and have common sense, I’d say go for it on your own. Just review and follow what you find in the maintenance manual if you have it. I’m all about saving cash too. Good luck! you can download the 2018 manual for free here: https://drive.google.com/drive/folders/1xOzbrZQDO_W_AxpjvHU1xJMOqfRsVfPJ

Hola Sherpa71, espero que disfrutes y recibas muchos buenos consejos de los demás miembros del foro. ¿Estás cerca de la Vuelta a España? Me da mucha envidia si estás. ¡Bienvenido!

Ukbta, welcome! I’m 64 and took up trials again three years ago after a 45 year gap. I’m not fat though but you make it sound like it’s fun. I may give it a try myself. Also, my friend from high school, just started up again too, and he is fat and is enjoying riding again immensely. We met up up in the Owyhee mountains in the Idaho desert just a month ago to relive old times. We had a great time! No, we’re not experts at all but it’s still a blast. Give it a go!

I did and I’m sorry I didn’t post the solution sooner. The reason I couldn’t get fluid to flow was that the adjuster screw on the lever needed to be turned out just a little. What happened is that the piston inside wasn’t opening or closing enough to reveal the ports in the cylinder. It was sealed tight by the piston. Adjusting the lever a bit allowed the piston to move farther, into an open port configuration. if you’re having the same issue, turn the adjuster screw either in or out. Hope this helps!

Yes! Use quality tools.

It could be also that you need to adjust the screw on the lever that presses on the master cylinder piston. If the piston is not in the correct position, when pressed or opened, it effectively blocks fluid flow and won’t drain and it won’t allow fluid to flow from the bottom up either. Screw it out a turn and try again. Turn the screw, little by little, until you can pump fluid. Another possibility is that one of the ports inside the cylinder could be blocked by debris. Use a very fine sewing needle to clear it out.

A lot of those Gasgas 300s have been returned because there’s too much power the rider can’t control. That’s why you’ll find them for such a great deal. Totty79 gave you some valuable advice. I have a 2023 Gasgas 250 TXT and had to lower the compression and put a flywheel, slow throttle and taller (11 tooth) front sprocket on it before I was comfortable. It’s now basically a clubman bike. Also, I got my 250, brand new, on sale for $4,999. If you look you’ll find a good deal too. Try Motohunt: https://motohunt.com/motorcycles-for-sale?q=Gasgas+250+txt&sort=a and search for least expensive. I just saw this one https://motohunt.com/l/7046299/2024-GASGAS-TXT-Racing-250 for $4,999. I don’t know where you are but if you’re in the states you can have it shipped for a reasonable cost. I had mine shipped from Georgia to Oregon for $300 through Uship. Good luck!

I couldn’t find any when I last looked. Most trials pants don’t even have pockets. I got some MX pants instead and have been very happy with them. They don’t have built in pads but do allow room for knee and shin pads. They also have leather patches at the knees to prevent burns from the exhaust. As far as hip pads go, you’d likely have to buy shorts with padding sewn in and wear them under your pants. They make them for mountain bikers and other active sports. There are both summer lightweight MX pants and fall/spring pants. There’s a much wider selection of MX pants out there than there are trial specific ones. Bonne chance! P.S. - If you do buy padded shorts or separate pads I’d recommend D30 type non-Newtonian liquid pads and not just foam. https://www.d3o.com/partners/solutions/ https://g-form.com/collections/baseball/products/elite-sliding-shorts
