I made this seat for my ‘23 TXT. It’s made of two types of foam. The first is a closed cell, very stiff, foam I glued up from half inch sheets and the second foam is a soft, 1” thick, closed cell, neoprene in the area where I sit. The arch below is reinforced with 6 layers of fiberglass and the whole thing is attached to the fender with 2” strips of hook and loop. It’s very secure and doesn’t move around. I then sprayed the entire thing with Plastidip rubber. It wearing very well and if it peels or cracks I’ll just spray it again.

Hey! I agree with lemur 100%. I had the same issue with mine, when I first got it, and soon found out that trials bikes are extremely responsive with just lightest touch on the throttle in first gear. It’s intentional to go from 0 to quick very quickly to hop from rock to rock on the back wheel for example. That’s not the style I ride though so I put a flywheel weight, a 1mm head spacer, a slow throttle and changed the front sprocket to an 11 from 9 on it. It tamed it down considerably so I, a novice, can handle the bike easier with better throttle and clutch control. The flywheel weight and front sprocket change had the most effect on mine. Aside from all that, starting out in second gear may help you also to relieve the “jerkiness” out of it. Also, like lemur mentioned, use your clutch to smooth it out. Also, try reading this thread. https://www.trialscentral.com/forums/topic/78583-s3-low-compression-head-replacement/

I had one of those when I was a teenager in the 70s. Those are fantastic bikes and I’m really jealous of you for having it. I wish I had kept mine. It looks like it’s in fantastic shape too. Most of them I’ve seen for sale always have a couple of huge dents in the gas tank and rust everywhere. Even the seat looks in good shape. Keep that thing!

I’m very very late to the party on this but am still impressed by your work cascao. Nicely done! I just finished making a new larger brake foot peg. I don’t have a lathe or a mill just a cordless drill, disc sander and files. Not as impressive as yours but I thought it turned out ok for my first foray into “machining” parts. I drilled the largest holes with a spade bit. It actually worked.

All the specs are on the last page of this PDF. https://www.montesa.com/wp-content/uploads/2025/01/25YM_MONTESA_EN_WEB.pdf

That looks fantastic! I wasn’t expecting to see it in such great shape after only seeing the photos of the ignition. Well done. I like the Mini Cooper too! I’d love to see more pictures of that also but that’s probably not allowed on a trials motorcycle website though. Maybe if you put the bike in the boot of your Mini (I understand there’s lots of room inside those little cars) you could bypass the rules. 😉 Cheers!

I agree 100% and do have personal protection. Besides my boots I have a full CE 2 rated kit for my torso, shoulders, elbows and knees. I only have one riding buddy at the moment but he rides a Japanese enduro bike so most of the tools required are different. We each carry our own but we do share universal tools and gear when needed. Thanks for the input! I appreciate it.

Thanks for all that and I agree wholeheartedly so I think the best I can do is to put another entire bike in my backpack and then a third one across the front forks. Just in case... 😉 Nah, I’m just looking for the most common failures. I guess I should’ve mentioned that before. I’m in the process of getting some extra levers. Thanks much!

Just added superglue to my kit. Great suggestion! I also added some bacon strips (my palate doesn’t fancy “turds”) as mentioned. Yum!

Thank you Faussy! Good to know! Exactly what I was hoping to hear!

I very rarely ride sections where my car is parked 20 yards away but more trail riding where my car is miles away and I’m just wondering what others, who ride similarly, take along with them. The things I take are carried in a backpack and include basic tools (sockets, Torx sockets, screw bits, pliers, spark p. wrench), spark plug, first aid, phone, tire pencil gauge, extra air filter, tire sealant, extra fuel, small flashlight, silicone tape, wire, zip ties, 2 chain quick links, and water. I don’t carry tire irons because I’ve had very good luck with sealants. I’m also not interested in clothing because that changes with the seasons but I’m wondering if I’m missing anything else important that I haven’t thought of. What’s something you needed but didn’t have? I should also note that the tools I take are the ones I do my maintenance with hoping to have what I need. Thanks!

Watch the first video in this article. Sammy Miller takes the flywheel off himself. He just uses a strap holder and a wrench. No puller. He also briefly mentions how to adjust the ignition. Hopefully you can see what he does. Good luck! https://sammymiller.co.uk/sammy-miller-mbe-unveils-newly-restored-miller/

Scorpaian: People have been trying to help you and you argue and throw their help back in their faces. They’ve been generous with their time and effort. You should say thank you instead of getting p****d off. You’re the problem on this forum not the others. Lemur, Konrad and others have been very helpful to me in the past and have been gentlemen about it too.

I know that the 2023 model 300 is .3mm. I would assume it’d be the same then in 2020. Hope this helps.
