  1. As a former competitor the main pieces of advice I would give to a new rider at the SSDT are:

    1) prepare yourself physically (although it's too late now to do significant training for this year's event) - they are long days and you will find things very challenging.

    2) don't hang around looking at sections, time can be tight and you must keep up, in fact give yourself a bit of leeway for getting stuck on the moors or having machine trouble if you can. The experts who spend a long time inspecting sections are also those who can absolutely fly over the moors to keep up on time.

  2. Like you, I've never been asked to have an eye test (l'm 67 and had a licence continuously for years).

    Likewise I've never heard of over 70s needing a medical for trials, and I'm sure I would have done so if it was the case.

    Please let us know how it gets resolved for you.

  3. I rode a TY175 at the same time as you in the 70s Tyupandover. I'd still say it's a good enough bike to hone skills on as it is, provided it's well set up, eg good tyres at the right pressures, brakes cleaned out and adjusted, ignition timing bang on, cables libricated, no slack in throttle cable, mixture tuned to run as crisply as possible, new air filter,  fork oil correct, decent rear units, chain tension correct. This matters on any bike of course, but well worth it on a TY175, and really the difference between a good bike and one that'll cost you needless marks. 

    Standard TY175s did very well in the day, winning trials against the best Spanish opposition. In my experience it was one of the best bikes for developing one of the most important aspects of a good rider: precision. Rather like a modern 125 these days. Just get it all as well set up as you can and then get the hours in practising on it!

  4. I use Hammerite for lots of applications on bikes. I just give worn bits near footrests etc a quick dabble with a paint brush if it looks scruffy. Keeps things looking fresh for a couple of minutes' work.

  5. Just a thought...the latest model of 247 was 237cc and had a different timing figure. Could it be the Electrex system is set to the figure used on previous 247s and is giving a retarded spark on your bike?

  6. I rode a TY175 in the 70s, with, for me, some success. Today, one which runs as it should will get you round trials reliably enough, though the gap in development and performance between it and modern bikes will be immediately evident. Depends whether that is an issue for you or not.

    By the way, the 175 was introduced in 1975 so the one you're looking at will be at least as "young" as that.

     

  7. Should be able to insert a rod or tube (I use an old socket extension rod) through one bearing and the spacer to (just) engage with the inner lip of the bearing on the other side, then drift it out by hammering on your tube. Spacer will then fall out and you can easily get to the the remaining bearing.

    I may be a little old fashioned but when a multi million ££ company develops a machine and plough millions into getting it right, why would someone with a  couple of hundred quid spare think they can improve it for the better ??  just my thoughts :)   Like people who put stickers on cars :)  I do think you may be right though. 

    Motorcycling history is characterised by owners carrying out modifications, some minor and some major.

    Sometimes this even leads to factories adopting changes.

  9. Make aure you test the cable after refitting it by turning the handlebars fully to right and left, engine not running. As you shut the throttle you should hear a click as the slide bottoms in the carburettor. If you don't hear this, you need to dial in a little slack on the cable with the adjuster on top of the carb. If the cable isn't bottoming properly the engine revs will race on start-up.
