Classic Trials

I need a carb to airbox rubber pipe for my '75 TY250B. They seem to be unobtainable, does anyone know of a supplier or an alternative pipe that could be made to fit?

Hi where are people getting replacement simplex primary chains from, now in-motion is out of stock of these chains? What is the correct size of chain? I just wondered if a different manufacturer makes something that’s a direct replacement for the joresa chain? Any help in getting a affordable replacement is very much appreciated. thanks 🙏

Good morning, I recently purchased a RL to restore - does anyone know what engine the RL crosses over to? I need a chain guard cover for the left side. Thank you in advance.

Greetings, I altered a Suzuki 185 trail bike for trials service and it's coming along pretty well. The motor is stock and I made a pipe to get it going and now want to make improvements with pipe and port timing. Most of what I need can be found in factory data or engine measurements except engine RPM range typical in amateur trials. I would guess 800~6000 with peak around 4K? Does anyone know better? Thanks!

I am doing research into the Cotton Mickmar project and am looking for a photo of the bike. I have this newspaper article with a of Eric Lee holding the frame he built for the Mickmar engine. I have been in touch with Michael Martin who made the engine and John Close who rode the bike for a season for the Cotton factory and they have no photos of the bike either. Any help would be much appreciated

TY175 questions but reed valves in general. In talking to a reputable engine builder he said that "in his experience a softer reed pedal worked better for trials applications." I have replaced my stock reeds with a set of Boysen reeds but couldn't feel any difference, thoughts? Could you tell a difference or is it an accumaltive increase with each little bit making it some what better? I didn't get to ask him about the metal reed stops on the reeds, would the work better in the stock positions or would they work better if you "bent" them so they would open wider or again would it be a waist of time and energy? This is all in search of the just a little more low end grunt…

- Honda 1976 TL250 Trials - new clutch? I've had the bike a few years, but ridden it very little. It came with piston slap, valve problems and other issues. Enough so that power is pretty weak. So I'm overhauling the engine. But because I've ridden it so little I'm not sure about the clutch. Mostly likely I'll just replace it. (The clutch pack was sticking when I purchased the bike). I'd like to hear from an TL250 owner. Seems to me (as the bike is geared so low) that with the clutch out, and enough throttle the front wheel ought to come right off the ground. Sound about right? Thanks, Dobbin22

I bought a Sherco 290st the other day and its great apart from the clutch. When started from cold the clutch won't disengage so if you drop it into gear the bike shoots forward. If you keep dropping the clutch with the engine off and rolling the bike back and forward it frees off. I take it that's not normal. Also once riding the clutch does seem slightly heavy I don't know how heavy it should be but I'd say it's sightly heavier than my mx bikes clutch.

In the 1980s I used to muck about on trials bikes such as a Moto Gori 250, never done comps just enjoyed trying to become better at using the bike. so now I want to buy a trials bike for much the same reasons and maybe in some distant future have a go at an easy beginners event but I want to enjoy taking time to get used to any machine I buy. I am slim and fit enough so no worries about that, just missing skills and abilities I have been looking at the new montesa 260 and also classic bultaco project bikes so trying to stay open minded After taking with a montesa dealer it seems that 2 strokes may need a piston after 200 hrs and then nikasil lined the…

Hi, I am in Edinburgh and thinking of joining a local trials bike club so looking for suggestions. I am not good enough to enter competitions and would rather just access practice areas so no point in joining a serious competitions focused club. I discovered the East Neuk wobblers (in Fife) and like what they say but no response to emails and no phone numbers so it may be a dead club but looked like what would suit me. Thanks

Hi Folks, I was watching scottish classic trials when I seen a couple of what looked like home made trials bikes possibly using chinese engines, (about 3 mins in) Does anyone know what these are, how they are allowed to compete in classics? I'd enjoy to make one of those if there was any info on building... Regards

Okay, I know that this is sacrilegious to even suggest this ….but I want brakes on my TLR200 Reflex. Before everyone looses their minds and start yelling for me to learn how to ride and to use engine braking and what not let me explain. I am not fortunate enough to have a practice area in my yard nor do I have a way to conveniently transport my bike most days. I have a bike carrier that hooks up to the receiving hitch on our SUV but my wife is generally driving that, which means that I have to ride my bike TO the places where I can ride my bike. As you all know the brakes on the TLR are garbage. Being that an older lady pulled out in front of me the other day when I was o…

A lovely sunny day in Hampshire https://img.gg/UTQex9w

Just been at the Trialsday.com training course today with my Ossa MAR and whilst i can wholeheartedly recommend the course, the Ossa let me and itself down by dying. It had been starting first kick, running sweetly and i was really enjoying it until it died. It was drizzling, which may be important. Back at the car i stripped the carb, flushed out all the jets and every now and again it would pop or fire up but wouldn't sustain life. Once i got home, a 2 hour drive it fired up instantly. The course was the first time it had been used in anger since a full rebuild by Steve Sell so guess seals should be fine. I'm thinking water in the period metal kill button or t…

Hi, does anybody happen to know what the different positions on the Yamaha TY 125 ignition switch are for? Thanks!

Hi guys can anybody help with info on how to remove the speedo drive from an HT5 rear wheel. I am used to Norton ones which just pull off. I believe the HT5 drive has a locking ring is this the C spanner ring behind the speedo drive? If yes is it LH or RH thread? Need to take it off to get my spokes repaired

Does anyone know if inner tubes have a shelf life? I’ve just found a few new boxed ones from the 90’s are they any good? They look ok, boxes are a bit tatty!
