  1. You don't really get the choice. What we might call trials chain comes packaged in a standard length which is longer than needed for most bikes. It is then shortened to suit. Off the top of my head I can't say what the 4RT length is but you can work it out from what was on it by counting the teeth and adding or subtracting as necessary based on the length of the old chain (I'm assuming non standard gearing from your question). As you don't have a local trials dealer up there you will likely be going mail order - a good dealer will chop the length for you but far better to get a chain tool as well and do it yourself to suit the bike. There is good scope for chain adjustment on the 4RT due to the two threaded holes for the stops. I run mine on the one that keeps the wheelbase as short as possible, which may differ from as they come.
  2. I must have missed a page somewhere along the line.
  3. Conrod lift would indicate big end play. To check mains you need to try to lift the end of the crankshaft ie try to move the flywheel up and down.
  4. Any update then Chappo?
  5. You could hold the flywheel with a strap wrench to tighten it.
  6. Even better - cut some plastic tubing to form rings.
  7. Don't think I'll be sharing the trench digging, thanks.
  8. That's more or less what I thought but up my way they always have a completely separate course of a much reduced severity so no mingling.
  9. Despite all the above I have to say I seldom see queue jumping these days. The only mildly irritating time was at a Yorkshire event last year when the entire Oset entry would pitch up at a section and expect to just immediately go through as a group. Clearly that was the way the organisers ran things so that "minders" could work as a team, so not queue jumping as such.
  10. Before I got a proper trials rider's car like a Berlingo I was without a trailer for a while. I used to remove back wheel and slip the forks and wheel out to fit the bike in an Astra hatchback, so anything is possible if you can stand the messing about but you don't really want to be doing that. My Doblo has a load area 1600 by 1200 wide; the bike sits diagonally and just fits. I don't know how long the Agila is but it looks narrow so there may not be enough width to get a sufficient angle to fit a bike in. Sorry I can't give specific advice but the above might be a guide for you if nobody replies.
  11. Can't the Beta importer answer the questions?
  12. But the van has a bulkhead which prevents the forward movement of the seats giving a little more room.
  13. I assume GTX appeals because it is not overpriced to the same degree as motorcycle oils? May well be OK but the 4RT, I feel, runs a lot hotter than a car and with not much oil in the sump so I prefer bike oil. On the other hand, at recommended change intervals, it's not in there for long. No doubt more technically qualified contributors will be on soon. Tesco can be a source of Castrol bike oil at a drastic reduction.
  14. My Bultaco rebuild days are ancient history now but I used a guide from one of the weekly papers that had been written by some guy name of Miller; I believe he rode a Bultaco. Drift mains in to heated casings then tap crankshaft in to place. Nobody had a domestic freezer then so the question did not arise.
  15. How much overlap does that leave?
