  1. If the top riders are so good why do they need a minder to tell them where to put the bike??????

    I mentioned in my other post that it was quoted that a rider took 4 minutes :rolleyes: to complete a section in the intercentre team trial, then teams were excluded for not completing in time.

    If this is typical no wonder the entries are small if they are waiting for the balancers to make their mind up or await the minders instruction.

  2. Hi

    I started trials in 1964 (Southern Centre).

    Rules were simple, 5 = stop (no forward motion), 3 = Foot down more that once, 1 = dab and 0 =Clean.

    This applied to all riders and we all rode the one course.

    Entries were 100 plus and you needed to get your entry in quick.

    Initially as a 16 year old I used to ride to and from the trials, the furthest was Poole to Sturminster Newton.

    I gave up to get married in 1974 but at the time I noticed an abundance of keen Dads minding (riding around the course) a not so keen son who had no serious interest and did not have clue what to do if the bike broke down. This had two effects A) They delayed the entry and :rolleyes: caused more damage to the route.

    Imagine how surprised i was to read in T &MXN that the top riders now have minders!!!! I never saw Sammy Miller, Alan Lamkin, Bill Wilkinson, Don Smith, Gordon Farley, Lawrence Telling et al with minders, they just got on the bike and rode the sections (after a good look).

    Then I read that the entry for a World Champoinship round had less top class entries than the point positions available, the event was only possible as the ranks were made up of Junior classes (which is excellent young riders need to be encouraged).

    Surely we need to go back to basics and make to sport simple, sections achievable and more enjoyable.

    Before you all fire off replies this is just a view, I have no experience of the current bikes and perhaps it is there that the problem lies, they are just so good, but that is progresss.

    I read last week that in the team trial in Cornwall, teams were excluded as they ran out of time, yet it was OK for one rider to take 4 minuites to ride a section(what is going on).

    I have just finished a total rebuild on a Model 91 Sherpa and have 198a in progress, and, hope to do some twin Shock events soon. I will be road registering them the so that, I can, if needed ride to the event and home afterwards.

  3. Hi

    I am in the final stages of rebuilding my Sherpa 80 series motor.

    Bottom end is complete and fine.

    I am about to fit the new piston and any clarification on side play at the small end would be helpfull.

    I have 2 Sherpa the other is a 198-A which has recessed spacers between the needle roller and piston.

    The new piston for the 80 engine is not machined either side of the small end, so my question is :-

    A Do I turn some recessed washers and equalise the conrod with the pistons centreline minimising side play.

    B Not worry and just use the plain washers supplied by bultaco UK and thin them to minimise the side slack on the end of the rolller bearing allowing the piston to self align in the bore.

    Kind regards

  4. Hi

    Thank you for the advice.

    It really is the only the colour spec I require as I have an Iron Phosphate pre treatment line and full powder coating facllities at our Bingley factory.

    We do a very bright silver for our furniture but it would not be any good for outside use and all the other silver powders I have been offered so far looks dull.

    I have had the frame sand blasted and am currently checking for any cracks.

    Will let you let you know how I get on.

    Have looked at your bike on the other posting and it is BEAUTIFULL Bultaco never ever made them that good.

    Kind regrds

  5. Thank you all for the advice re the back plate, no joy so far but will keep looking.

    Are there any other alternatives that would get me mobile, say more a popular hub that I could get built up?

    Other news, sorted out the wiring from the low tension coil, fitted new points and it fired up second kick!

    There is plenty of compresion but it is a bit clanky on tickover, but at least I know it is a runner.

    Kind regards

  6. Hi

    The bike is complete but has not been looked after.

    The frame has been really trashed around the primary cases but it is straight it just needs a complete going overgoing over.

    I know where to get the work done but my mistake was not researching the brand and not picking up on the fact that the rear brake plate was not original.

    My plan is to get the engine running and check for strange noises if none then strip down sandblast and powder coat the frame and gradually put it back to standard.

    So far I have fitted a new Kick start spring, Air filter and am shortly to fit points and condenser.

    I have worked on numerous Trials bikes in the past so this was seen as nostalgia trip ending up with a working toy in the garage to keep my Street Triple company.

    Back in the sixties I had a 197 Scottish, 24 tes Greeves, a new 1966 Anglian, the first Montesa Cota out of Westbury motorcycles in 1968 and finally a 1970 Greeves Pathfinder followed by the ex Paul Dunkley Cheetah. But I never had a Sherpa.

    If you are interested I can email photo but i do not know how to post them on the forum.

    Kind regards

  7. Thank you for replying.

    Basically I want to get the bike together and running before I decide how much I want to spend.

    To give you an idea.

    Front hub needs sleeving

    Lower tubes under the engine need work,

    Rear hub needs re chroming

    Mikuni carb does not look like the normal in fact it may be off a road bike.

    Now, I realise that I could get a complete wheel assembly for another Sherpa but it would be nice to keep it original.

  8. Hi everyone.

    Need some advice please.

    I am rebuilding my bike to original, it needs a lot of work.

    Before I strip it down i need to run the engine and check the gearbox functions.

    However I am stuck for a rear break plate.

    The problem is that mine has the (I think) Pursang rear hub, two piece hub held together with M6 Allen screws.

    Tried Bultaco uk but they cannot help.

    Any suggestions would be appreciated.

    Thank you in advance.

    Martin
