  1. 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.

    Of all my bikes, trials, road or racing, my Greeves Scottish is my favourite....

    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.

    I don't see how it can be any easier than it already is. It's at the bottom every time someone makes a post. Yes, there are storage limits on non-Supporters, but I don't have Zuckerberg's billions, millions, thousands or even hundreds to throw at resources.

    Andy I suppose like the SD card in my camera storage space on your website is finite.

    I am a bit reluctant buying air tickets, train tickets (or rent a car), hotel and two days entry tickets plus a few pints, going all the way from Sweden to Telford. Perhaps it is a well spent couple of hundred pounds, but I don't know, having never visited this show before.

    What do you veterans of the show have to say, go or save, staying at home in the dark and snow....?? Please, give me your honest opinion!

    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.

    A few years ago I bought a couple of brand new oval alloy barrels from a supplier who shall be nameless in the UK and fitted one to my trials Cub. After about two events it had smoke and oil spewing out all over the place and required stripping.

    I found that the liner had spun in the barrel which misaligned the oil drainage holes resulting in the problems I experienced. I tried contacting the supplier who ignored me completely and I would add that the supplier wasn't UPB, AWR or Armac, but he is well known around the UK.

    Can anyone tell me if this problem was rampant or was I just unlucky getting a couple from a bad batch, I have always been afraid to use the other one that I bought off him.

    Is the problem ongoing or has it been fixed, I have heard of other problems such as warping, siezing and excess oil burning.

    For the money these alloy barrels cost you would hope to get better service out of them.

    If my supplier wants to contact me to offer a solution :D or anyone else wants to talk off air, twinshock2@gmail.com.

    Cheers 

       

    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.

    My Bultacos and OSSAs have Betor forks. The brand is stamped into them. I can't remember what is marked on Montesa forks apart from the big M. They are similar to but different to Betors on the inside.

    Montesas had Telesco shocks while OSSA and Bultaco had Betor shocks.

    What prompted you to wonder about this? The Spanish bike brands had lots of parts made by external contractors. I learned today that a Bulto company made the Mahle branded pistons used in Bultacos under licence in Spain (and a very nice job they made of them too). The handlebars for Bultacos were made by another company, as were the frames and probably lots of other parts (a lot like nowadays where the parts for a new trials bike are made by a myriad of suppliers). In the case of the Spanish brands in the 60s, 70s and 80s, there were import limitations imposed by the government so most (all?) of the components had to be made in Spain. Today's bikes come together from all over the world.

    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.

     Apparently that's what I have as there's no flat filter in the bike or any of the boxes of old parts I got with the bike. It came with a cylindrical filter that's glued to the intake boot. Is that the 199B filter?

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

  8. 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.

  9. 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?

    Hi. Was wanting to get started in trials and have been looking for a beta or gas gas 250 but have seen a nice beta rev 3 270 for sale at a good price.  Do you guys think the 270 would be ok for a beginner or should I wait and try and get a 250.

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

    I went and counted the rear yesterday (before I had anything to drink). It is a pretty big sprocket and yes it is slow in first but it's never troubled me. However I don't actually like the way it looks (so big) and now with this discussion am thinking of fitting a smaller rear and giving that a go

    OSSA June 2008 009smaller.jpg

    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.
