  1. Gerry Minshall is one of the best sources for many pre 65 parts. Look him up on Facebook.
  2. Try https://www.tytrials.com/
  3. I've never even seen pictures of 2 up seat for txr312, I'm not sure the sub frame was designed for this.
  4. Or just go to a friendly / educated test station and save the hassel 😎
  5. One of the reasons they didn't use the clutch, back in the day, was because you couldn't 😂

  8. I ran a 428 chains on a 120kg bsa for many years (plus 80++kg rider) More than capable, and lighter as stated above.
  9. Stamp the number !!!!

    I think there should be a felt seal on the sprocket side. Thinner oils and higher temps will exaggerate the problem.
  11. Can you not achieve the desired gearing with a few more teeth on the rear ? More flywheel would slow the engine response ?

    You sound a nice person ....
  13. Is the air filter properly oiled ?
  14. b40rt replied to netley's topic in Montesa
    Upped the gearing, they were good for 70mph in standard form ......
  15. Not jgas specifically, but some get leavers require a wedge (plain screwdriver) tapped in to open them slightly to fit.
  16. The condensor/capacitor in the picture is damaged, if you didn't do the damage, this is probably your problem.
  17. Volkswagen 👍 12v is fine.
  18. Check the part number for points as I wouldn't be surprised if several models used the same ones. Move the condensor and mount it by the coil (I use vw ones)
  19. Change the condensor, points and plug and try again .

    A correctly designed expansion chamber, with long front pipe and absorption type silencer can be very effective. Excellent low power and acceptable noise level.
  22. The lower forks appear to be maybe 3 pieces ? ie heavily modified so the original spec may not be to relevant.
  23. Pull the old one out, it should be marked on it. Or. Measure the stantion diameter, the inner diameter of the leg and go onto bultaco uk site and match the size. The depth isn't to important as you appear to have plenty space. https://www.inmotiontrials.com/?s=Fork+seals&post_type=product
  24. Some ssdt riders have a legal sized plate attached to their backpack.
