It would never be better than a Beamish Suzuki, which is at best a ho-hum prospect for twinshock trials.

Nice video. And it gives the rest of us hope that one day we, too, could rise to the ranks of Daredevil Bikers.

Definitely 315 Unless of course it's had about 15 owners and been hacked around and neglected for half its lifetime, and the Gas Gas is a cherished beauty which has been looked after. In other words, you can't make a definitive judgement on make alone. At this age, condition is everything.

Agreed. Trials has probably profited from being a low key sport, out of sight of the general public, in fact for me this has always added to its charm. Only this week a TC member posted to say how happy he was to ride his bike on any piece of private land he fancied without bothering to seek permission. There is a point where attracting more people to trials will increase this sort of dangerous and irresponsible behaviour, such that trials themselves will suffer.

Is the squeak there all the time or does it sometimes disappear? Does the frequency vary with speed of the bike? If so does it coincide with the chain doing a full rotation? If so that would be the easiest thing to eliminate. Although you've checked it by rotating the wheel slowly a dodgy link might show itself at higher speeds.

for me, dry = 6 psi 4, wet = 5.5 psi 3.5 good body position and throttle control is most critical in wet. rob Same for me, but for practising I've taken to raising the rear pressure by up to 2 psi to hone grip-finding skills (a technique once recommended by Mick Andrews as I recall).

Nice bike - as a side issue, are those old original Hydrobag rear units still damping? They seemed to give up the ghost long before this age!

My 1979 247c runs on 9 tooth front/40 tooth rear sprockets which gives good ability to cope with a general mix of sections and allows second gear to be used as a realistic option.

...and stifle development

Thanks for posting these results. For me a couple of results which stand out are Dave Thorpe, still riding to win and finishing well up the first class awards, and perhaps even more noteworthy one of the most "senior" competitors Colin Dommett claiming 7th out of 86 finishers in clubman pre 65.

Or wheel rims...

Helduns were made in the Birmingham area I think, in mid to late 60s. They did a scrambler and a road racer as well as a trials bike, all of 65cc I recall. I believe the trials version was called the Heldun Hammer, perhaps the only bike to be named after the trials rider's tool of choice.

Replacement liners are available from Diadora dealers

The big issue would be how people who wish to ride non-competitively would access land where they could do so legally and with all relevant permissions. In the UK trials operate under the auspices of clubs who often restrict their use of particular pieces of land to a specific number of times per year to maintain good relations with the landowners, and riding is strictly off-limits except for organised competitions. The days of "waste land" or "common land" where casual motor cycling can be legally undertaken are long gone. I am fortunate to belong to a club which owns its own (excellent) land which can be used by any full member at any time and there are "social groups" who go there to ride non-competitively in the way you describe but this facility is rare indeed these days.

How about disgruntlement with the non-stop rule/boredom with similarity of sections/lower order riders finding sections are bit beyond them?

Could be right about air cooled monos picking up in value over the next couple of years, and if this is a good one (hard to say without photos but the fact that it still has lights attached suggests it may be) it could be worth a punt at around £800 to 1000. Then again a TY 250 mono could be an easier bike to get on with, being the clubman's favourite of the time, and there are lots around.

I'd be happy to support a new publication if it was a quality (as opposed to "tabloid") product and had decent standards of proof reading, which appears to be regarded as an unnecessary luxury in the current monthly. I would also welcome well written opinion columns and informed articles on training techniques. My preference would also be for inclusion of modern and twinshock/pre 65 material in the one publication. I really think the use of talented writers in a well presented and intelligently written magazine would be a great addition. Even if it flounders after a year or two at least you will have done your bit for the trials community to the limits of your capacity, which is all we can ask.

Good spotting - a lovely chap as I recall, who would turn out week after week in all weathers.

I think that is one of the Jefferies Hondas, as derived from the XL250 trail bike by Peter Gaunt. The M registration would place it as 1973/4 which would be correct for the bike which I recall first appeared at the 1974 Scottish in the hands of Gaunt and Nick Jefferies, who led the trial at one point. Sorry can't help with the rider in the picture but could well be a Yorkshire trial as I think most of the bikes were sold locally.

Lovely job, well done.

Not recommended of course , but you'd be surprised at how many people rarely, if ever, touch the thing.

Good post bultaco340. It's the human element, which can involve leniency, inconsistency etc, that can allow problems to creep in. But as is commonly stated, we can't have trials without it, and we're grateful to the observers we have. Electronic observing which might determine whether a stop is really a stop, isn't with us yet. I guess similar issues arise at the local tennis club: hey Mr Umpire was that match-deciding shot we just saw in our out? On the line or just beyond it? Electronic hawk eye? Not at this level mate. Video replay? Ha ha, you must be joking. Just make a judgement on what you saw in a split second. Do your best, try to be fair, and ignore any complaints. And remember, whichever way you decide the winner will enjoy the plaudits and the loser, well, they'll make their own arrangements. Then everyone will move on to the next match. Just a game, after all.

The suggestion was 1 for a stop instead of 5 with no other changes to the scoring system, so a thundering fail would beat a two dab ride. Doesn't seem quite right.
