I rode new Sherco 250 and 125 two strokes for several years and before that Beta two strokes, competing in Trials - usually Novice sections every week. The first thing I always did was to explore methods for softening the power delivery - flywheel weight, low compression head, retard the ignition, smaller/larger sprockets etc. I tried a Sherco TY125F, but in my opinion it is a Trail bike, not a dedicated Trials bike. "Sherco have no interest in developing this bike for Trials - we just sell them" - quote. Scorpa did limited developement work on a couple of these bikes in 1919, but no longer do so. To make them competitive you will have to do it yourself! (Luckily, in a former life I worked as an Engineer). The power delivery is different on a two stroke, because as the engine revs climb, so the power increases. On this 4 stroke, the power is less, but there is no step-up in power as the revs climb - no power band, just smooth, constant power. Much softer, tractable and controllable power. The Sherco and Scorpa TY 125F are exactly the same, just different graphics. The suspension is fine - as good as on a comparable modern Sherco 125 or a Sherco 250 two stroke (owned both and rode regularly in Trials). The front forks on the TY125F are different from the Sherco 2 strokes, but work well. (The frame and geometry are exactly the same on all of the bikes - only the front down tube is different). Ground clearance is a bit less on the TY125F - perhaps by 25mm. Lighter riders likely wouldn't notice it !!! Brakes are excellent. Fuel consumption is much less than on Sherco two strokes!

... "aren't affected by modern fuel" ... Brave comment!

When I see the words "shares" I know that the Moneymen will be chasing a profit. Profit first, everything else comes after that, including Trials.

I have wasted ages on the ACU website trying to renew my membership for 2023, with no success. Anyone else having issues? Thoughts on the new ACU website?

Where do I sign?

Join the ACU and enter a few trials. Just ride the Novice sections and do the sections that you feel happy doing. Welcome to the Auto-Cycle Union (ACU) - Bikesport GB

I have Wulfsport and Gaerne's. The boots offering the best protection by far are Wulfsport. Wulfsport boots are made of thicker, stiffer leather and the soles are much stiffer too. Gaerne's are soft and comfy but offer little ankle protection - I broke my ankle earlier this year wearing my Gaerne boots. It wouldn't have happened if I had my Wulfsport boots on. However, the most popular boot at trials competitions are Gaerne.

Some clubs have a Gentleman's Route, which is basically in through the start gate and out of the end gate, by any route at all.

Good advert.

Bend the kickstart back to it's correct angle: Take the kickstart leaver off. Put it in a vice. Heat it up with a blowlamp, or preferably an oxyacetylene torch to a red colour, then bend it, perhaps using a long length of pipe. When you are happy with the angle then heat it up again to red, then quench it in a bucket of cold water to make it tough again. Simples.

Easy enough to sort out a bent wheel rim. Youtube is your friend here. Don't waste money on buying cheap tyres.

You need a windy gun/impact driver to undo it. If you don't have one, take it to your local garage. (leave the nut exposed). It would only take them a minute to undo it.

Tool Station, Screwfix. Proper Job.

Mineral.

I would guess that being "mullered" has the same meaning as being Johnstoned, so messed up - broken - destroyed beyond repair.

My thoughts exactly.

Thanks Trapeze. I thought that it was just me.

Can anyone actually use the AMCA for Trials at the moment?

Why is the AMCA website so difficult to use, compared the the ACU?

I think that the "melted" overflow pipe is in fact a hole cut there on purpose to stop the pipe syphoning fuel from the carb. Poor starting = clean your pilot jet - again. Reset tickover speed. p

Here in the south of England, you don't see many old/real Montesas at Classic trial competitions. Some Bultacos and Ossas at every meet, but very few Montesas, despite them being quite common back in the day. I wonder why? Engines difficult to work on?
