My 247c had 10/40 as standard, but 9 tooth front is better for modern sections.

Once you're in a section and riding it, the physical input wouldn't be any less than on a petrol bike, I'd suggest. Quite possibly more, given the suspension and tyre shortfalls of the Oset. If starting a bike is an issue, the Tenaci Wong would merit investigation for its electric start. Performance is well up to competition standard and I think it's the cheapest new petrol bike you can buy.

Usual cause of only getting 1st and 2nd gear is that the pawls carrier is fitted upside down. The slot which holds the pawls looks central, bit isn't quite. Whip off the carrier, turn it through 180 degrees, refit and see if you can then get all gears.

No need to buy as a Montesa part. Cheaper and easier elsewhere.

Seems to feel a need to be a bit smart when straight talking would do. Style over substance?

Plenty of places on eBay sell M7 screws. I bought hex head ones for my Cota 247, cut them to length, ground the heads to a round shape and hacksawed a slot in the head. Good as the standard screws and not expensive. From memory I later found allen head ones on eBay which are better for the purpose, but haven't got round to fitting them yet.

If you search Hull Auto Club you'll see contact details on the ACU website.

That's a question which would have prompted several pages of debate not so long ago, but people seem to have run out of puff these days. Perhaps just jaded by it all.

There is another good thing about winter in my opinion: getting the bike out to ride in proper trials weather.

Maybe , but I've never had an insurer ask me to state what a bike's odometer says, and with no MOT data on a historic vehicle they wouldn't know unless I told them.

Like you I had a normal V5 for my Cota 247 but was able to obtain historic status registration without it being insured. I did enquire about insuring it at one stage (with Carole Nash) and was offered a policy with no mention of a speedometer.

Yep, may need some forearm workouts to hang on to it!

I agree. No reason why a body in its seventh decade can't be trained.

Peter Gaunt used the Super Six piston, making capacity 128cc from 118cc. There's a detailed article about the bike, including a picture of the lengthened swinging arm, on www.bsaotter.com in the article headed "Geekies Gizzmo" in the list on the right of the screen.

Thanks, appreciate the reply. Thinking of trying one on my Cota 247 - nothing wrong with the standard Amal but I was so impressed by putting an OKO on the SWM that for 60 odd quid it's worth a try.

I didn't know about that source, have you tried it yourself? Would be interested to hear your experience if so. Half the price of the ones from Mid Atlantic but are they the same, ie genuine OKO? Also a question of how they're jetted I suppose.

I looked into that and the answer is no. The previous importer no longer does them. You can find cheap Chinese copies on eBay, marketed as OKOs, but they're not worth having by all accounts. I dealt with Mid Atlantic Trials in USA and found them excellent. Cost was about 118 quid delivered and set up ready for my bike, with some extra jets and hose to attach to air box. I think that compares quite well with buying a new Amal or Mikuni in the UK. If you take a look at Mid Atlantic's website you'll be able to read about what they do with OKOs.

During a trial I carry some zip ties, a roll of tape, spanner to adjust chain tension (I'm fussy about keeping that just right) and an allen key for lever clamps (I keep mine slightly slack so the lever rotates around the bar instead of snapping off if I drop the bike). The above is probably a throwback to riding long lap trials in the old days when some maintenance/repair work during the event was pretty common. As far as I can see, almost all riders nowadays carry nothing at all!

I agree with feetupfun. Put one on my SWM and it pulls much better from the bottom of the range and runs cleanly throughout. Mid Atlantic are a good company to deal with and have worked hard to get the OKOs properly dialled in for specific models.

I have a handbook for the 247c and will pm you re sending a copy of the vital data. Meanwhile you should move the kickstart lever on its splines to the 1 o'clock position. If it's too far forward as in the photo it will damage the side casing.

This doesn't help you, but my first bike was a Dalesman. Would you mind posting a photo of the bike for old time's sake?

Thank you, very useful and unusual to get an experienced rider's view of the EM as a serious trials bike in comparison to petrol bikes.

Yes, various 3.50 x 18 trials tyres on eBay. May not work too well in the sections but might solve the problem.

Linklyfe was the nasty stuff you're thinking of.
