I think it unrealistic to expect to ride straight up to then into a section without some delay, it does give time to chat to other competitors also oportunity to see which line other riders are taking through that section or if the section has changed appreciably. Some observers are much quicker recording scores than others, a longer section takes a greater time to ride through especially if it is one of the more demanding on the day.

Yes quite agree but more sections = more observers and in my experience when organising trials they are a scarce commodity.

Lots to see you will not be dissapointed.

I have used this firm who are based at Sandbach Cheshire http://www.dynasurf.co.uk/ they have done a great job on forks.

I have to agree with you Spen, I have a 1961 Greeves Scottish 24 TDS this is the bike that got me into riding classic trials and is very much a favourite of mine although currently after a lot of use it awaits a tidy up. I know it's full history it was sold new by Dave Bickers when he had a motorcycle shop, I first saw the bike when in my teens, at that time it was owned and ridden by a well known MXer who frequently raced in europe the next owner but one was me.

Yes simplified instruction at last!...

Judging by the number of comments on these pages many do not find posting photos on tc an easy task.

I am familiar with both Bultaco and OSSA trials bikes but have never owned a Montesa they were the ones that got away,. The 348 has a certain appeal to me so thanks for all of your replies please keep them coming.

If pictures could be posted very easily straight from the computer it would be much better to show how something has been made or repaired when asking for or giving advice.

How might the Montesa 348 compare to a similar period Bultaco, is the 348 a good bike to own and ride?

I have used Niphos who are based at Crewe Cheshire, they have a good reputation and do work for a certain Crewe car company. http://niphos.co.uk

Telford is a very good show to visit for all things off road, nearly everything inside in the three halls just a smallish autojumble outside which is best to see on the Saturday. Telford itself is a postwar developement so1960s type buildings, not much to see outside the show in the town itself. Nearest airport probably Birmingham but Manchester or Liverpool or dven East Midlands not far either. Hope this helps should you make it have a great show.

The Martyn Adams Serco barrel on my Cub has been fine along with all the other work he did and parts supplied to myself and friends, might be worth contacting him http://www.mdamotorcycleengineering.com.au/pages/Martyn-Adams.html Why not try the other cylinder, you may have one good one and one faulty then at least you will know.

A conversation with a friend about shock absorbers raised the fork question. My Bulto has Betor markings on its forks but unsure if those on the OSSA TR77 are Betor.

I believe that the forks fitted to Bultaco, Montesa and OSSA were made by either Betor or Telesco but which suspension company supplied each bike maker does anyone know?

Yes it could well be, the 198b and 199b filters are shown on the inmotion website.

The air filter from the 199b can be fitted in the 199a air box, because the b filter is cylindrical it offers a bigger surface area than the flat one fitted to the a. In my opinion leave the yokes alone unless like me you are quite tall and find the riding position cramped, if so there are a couple of aftermarket top yokes available with the bars mounted over the steering stem.

Brucey if you look at a Villiers engine the road version has a full side case similar to a Cub but on the competition model it was cut off after the mag case leaving the gearbox side cover exposed as you are doing with your own engine. Villiers fit a pressed metal cover over the spring, maybe you could make something like this?

A Beta 250 or even better a 200 would be the best choice for you.

Gearing is very subjective but on a trials bike no use whatsoever if too high, does the engine run nicely at low rpm or does the carb need attention, maybe a worn slide, incorrect jetting or crank seals. All of these things if not right will make the bike less rideable also can you try another bike to make a comparison. Your OSSA looks to be in good original condition but some things must have worn or aged from when it was new.

The OSSA Pennine was 230cc, MAR 250 or 310 as an option on the later models.

Filter arrived today thanks Jon and Brucey for your help.
