Make aure you test the cable after refitting it by turning the handlebars fully to right and left, engine not running. As you shut the throttle you should hear a click as the slide bottoms in the carburettor. If you don't hear this, you need to dial in a little slack on the cable with the adjuster on top of the carb. If the cable isn't bottoming properly the engine revs will race on start-up.

If you try phoning Inmotion Trials on 01784 440033 (0044 1784 440033 if you're outside UK) they should be able to supply the puller you need.

Spark plug?

Quite a bit more steering rake than on the standard MAR.

I agree with rotors7. I've seen bikes do that with only result being shearing the woodruff key locating the flywheel. You could be lucky.

...and East Yorkshire 2 day near Whitby, usually early October.

Can also recommend Lanarkshire MCC 2 day at Fintry in Scotland in August, worth the trip.

Scarborough 2 day in August. Also do a twinshock 2 day in July.

You don't need an ACU licence to practice, and can ride any bike to do so.

Any photos of the bike pre rebuild?

I'm afraid I was quite distracted by the unnecessary music laid over the video, so it's difficult for me to comment.

I've always lived with tubes that creep a bit. Three things I do: - in first gear with dead motor, repeatedly jam the bike backwards against compression to correct valve position - extend valve hole lengthways with a round file - don't screw the valve lockring up to the rim, let the valve tilt if it's going to.

Yeah, sounds like it!

Blimey. Wouldn't get away with riding a motocrosser to the pub or anywhere else for more than two minutes here in blighty.

Correct. Well said Woody.

I seem to recall the 2013 300s were prone to this and a change to red cylinder head was the cure. Haven Trialsport can advise I think.

I was riding the SSDT when Thorpie was on the CCM (1979). He spent quite a bit of time repairing/rebuilding it through the week. A very game effort, but he soon returned to a Bulto after the event.

I believe the early Dalesmans (Dalesmen?) had Puch forks, from the M125 road bike.

If used trials bikes prices have been subject to inflation in recent months, this effect seems to be multiplied in the case of 315s. Be careful.

Hasn't he got a tie-up with Tenaci Wong now?

Bound to enjoy it once you get stuck in. Which part of Yorkshire are you in?

Fair point. What ratio of rider/bike performance contributes to a good result? 80/20, 90/10?

Yes, not like lemonade. Or the original bikes, come to that...

Thanks for this input. Other than launching the bike for big steps, I would have thought the clutch was superfluous as you can go right down to zero and pick away again smoothly on the throttle only. In effect, the bike is unstallable. Or am I underestimating the benefits of the clutch?

I've been having similar thoughts, and intend to test ride latest model this month. I did get a ride on one a couple of years ago but nothing about it tempted me to change (from the point of view of competing in trials - not sure if this is your situation). Relevant points for me are: - They're improving significantly year by year. Buying one now could leave me with a bike seriously out-dated by new model in two or three years. - Although it may cause less bother, riding it on private land without permission is just as illegal, with the same penalties, as a petrol bike. I accept this isn't important to some. - Virtually nobody in my area, which is a trials riding hotspot with loads of experienced riders, has made the move. Why? - Looking at the owners FB page, they're not entirely without their problems, and there is a reported tendency for the factory to be deaf to complaints or claims. - They do get loads of good reviews.
