The Jianshe/Yamaha 125 engine is a direct copy of the Yamaha YBR / TTR 125 engine - the same as fitted to yours. (Jianshe is 50% owned by Yamaha). Most/all the parts are interchangable. They are fitted to the new Sherco and Scorpa TY 125 4t. Also fitted to the new AJS 125 and many others too. You will need to get a small engineering company to make you a 39.5mm aluminium bung with a rubber o-ring made to seal up the starter motor hole (pull the starter motor to see what's needed). (mine cost me £20 a couple of years ago). Also remove the starter motor dog gear mechanism and the large gear wheel on the back of the flywheel. Leezy will sell you a big bore kit for it (e.bay). .

Boots for big calves? Something like this perhaps?

A 300cc bike is for Experts. Get yourself a 250 and learn how to ride Trials properly,

Apparently some dishonest people have use an electric grinder to remove the words "for offroad use only" from the side of their tires.

A Montesa 4RT is perhaps not the best choice for a Novice.

How much does a throttle cost? (£20, UK). Don't be a lazy tight-a*se! Buy one and try it for yourself. See what it does for you - experiment.

Lets hope it's just more ACU incompetence!

Entered a trial via the ACU portal. Now, at least a week later it says that my entry is not valid, due to my not having a rider number. Never been asked for this before. Spent ages on the website, trying to discover how to do this, but with no luck. Anyone know how to do this?

Problems: 1. Dissolves tank liners, including Kreem and Flowliner. 2. Dissolves O rings in fuel lines. 3. Corrodes aluminium alloys in carburettors.

This is what the information says - "Although our pumps have E5 labels on them, our Synergy Supreme+ 99 is actually ethanol free (except, due to technical supply reasons, in Devon, Cornwall, North Wales, North England and Scotland). Legislation requires us to place these E5 labels on pumps that dispense unleaded petrol with ‘up to 5% ethanol’, including those that contain no ethanol, which is why we display them on our Synergy Supreme+ 99 pumps." However, I believe this information may be out of date?

Esso Synergy 99 used to be ethanol free. However, I understand that this may not now be the case. Anyone know? Synergy Fuels | Esso

I put an S3 low compression head and a flywheel weight on a 2017 Sherco 250. It didn't really make much difference! I also fitted a smaller engine sprocket. That slowed it down a bit, although I later went back to the stock size. On reflection it was probably just getting used to riding that particular bike that made the biggest difference, rather than the modifications.

Yamaha engined Scorpa/Sherco = Sherco/Scorpa TY 125F.

You take the plug out and kick the engine over. There is a spark. You replace the plug and kick it over repeatedly, but it won't run: Look at the green ignition wire very carefully. It connects to a small bolt on the points via a small brass fork terminal. If that fork terminal is not fitted squarely onto the points connector, then it may/will arc across to the ignition carry plate, or even to the points cover when the spark plug is under compression, in the engine. If the fork terminal is placed on the outside, under the bolt's head, then it WILL arc across to the points cover, when under compression. Put the bike in a dark place - shed or garage. Turn the lights off. Take the ignition cover off. Get someone to kick the engine over while you look closely at the points. The point's contacts may/may not/sometimes spark. Disregard that. See if you can spot a spark elsewhere. That will be your problem.
