General Trials Talk

Thinking about tyres having replaced mine in the last few months, what are the thoughts on having a cheaper control tyre for classic events?

Just had a new very expensive X-Lite front and does anyone else remove the moulding flash like I do? I was surprised how much came off much more than recent IRC rear

Condition and price being pretty much the same, which is the better choice, a TY250 or a TL250? I guess the choice of two cycle or four cycle is the main thing? I lean a little towards four strokes.

On a frame-up restoration, anybody have the frame and swingarm powder coated? Tough finish but difficult to touch up scratches later?

This might not be the correct forum but... When I try to look thru all the posts on here I can look at 4 or 5 pages then I am taken to the last page. That leaves 100+ pages that I am unable to see? What am I doing wrong?

Hi, Reaching out for the contact details of the guy who is the go to for parts for the cotton trials bikes please. any info would be greatly appreciated. Many thanks Brent

I have wanted a Japanese trials bike for a long time. I've located a 1976 TY250. It might be the one to restore. It's biggest issue is someone has swapped on a larger seat. I'll be looking for the correct seat.

Hi all you lovely people I hope one of you can help or at least point me in the right direction. I have been given a Beta Zero trails bike that has a few wiring problems. I'm looking to get hold of a wiring diagram as I'm not sure if there are a few bits missing. I think the year of the bike is around 1989 1990 from what bit of research i have done. So I'm hoping someone out there has a diagram tucked in the back of there shed. Kind regards AR

Hi guys i'm buying a Fantic 240 but have a concern with kicking it up or lack of. Has anyone drilled and tapped the head to fit a universal decompressor kit or is their a certain technique people use? TIA

Hello everyone, I bought a 2020 Gasgas GP 300cc, with the red cylinder head, but I don't have the right compression, there was 1.2mm of base gasket, does anyone know what thickness is the original base gasket? Thank you very much in advance. Olivier from Belgium.

Hi all got a wireless apico hour meter on my Montesa 4rt with just 93 hours on it & its started to fade, ie battery running down does anyone know if you can change the battery like you can on the meters you wrap the wire around the spark plug cable doesnt look like you can for me Thanks Cookiemonster

Our ground is used by a local trials club. Weee very happy to host, I’m just curious on how much clubs usually give the landowner? Is it done by number of bikes or just a set fee?

Our friends at Rhode Island Trials Club have stepped up to put in the huge effort required to host the World Rounds / Wagner Cup for the FIM and AMA this coming July We ask for your support be it by pre-ordering tickets, volunteering, or helping to raise sponsorship funds. The projected cost is about 18x the amount of money the club has in its bank account. That being said, it will be a triumphant return of the sport's best and bravest athletes, it will be in a location with breathtaking terrain, and it will have incredible camping and paddock action. Two of the sections will be ADA accessible. Parking is free. There is also a trials ride available…

Since my new bought preowned Montesa came with bad tyres, I'm wondering about some soft enduro tyres. Has anybody tried this, especially rear (tubeless)?

Hi guys I’m having problems with rough running on the old 305 Iv cleaned the carb but it runs and idles with the choke out but rough and lumpy when I’m so I stripped the carb again to clean the 2nd idle jet the little tiny one but it’s clear I can’t get the slotted screw out the choke lever but all else is spotless in the carb also Iv notice it has a two stage reed valve which are a little open on one side think it was on the bottom do I mess around trying to clean and possibly turn them around or jst replace? And could the choke lever have anything to do with the rough running and again if so shld I replace or try n drill out and repair ect new carb is £195 and reeds are…

Can anyone suggest a good replacement for the existing Amal 626 carb Mikuni, OKO or similar.³

Heres a question, while i was sat at a section on my electric trials bike a rider pulled up alongside me and said, do i know if his lad could ride one of the electric bikes in the youth class! interesting point i didnt have the answer but the bike has a power switch each position is equivalent to 80cc. 125cc, 250cc and 300cc so in theory it covers all classes but i still dont know the answer to the question and i wonder if the ACU has ever thought about it
