  1. I've seen people fit XR600 (alloy) kickstart lever to the Yamaha knuckle, but they shorten them a lot to get them about the length of that one in the photo. I bought an alloy Honda lever for this purpose but haven't gotten around to playing with it yet. I've got an MX250B kickstart lever assembly and a DT250 something kickstart lever assembly as emergency spares for my TY250s and they fit all right but are pretty long and the MX one is very heavy and has a bigger diameter knuckle pin. The standard TY250 kickstart lever is quite a short and light thing compared with the other Yamaha dirt bikes of the era that use the same spline. I think the TY lever is so short because the kickstart shaft is at the top of the motor while the others are only halfway up the motor.
  2. Could also be a leaking crank seal on the primary drive side of the crankshaft. The test for this is if the gearbox oil is disappearing.
  3. The popular two strokes all depreciate due to age for about the first 3 years then their value becomes almost entirely dependent on condition. The desirability of particular brands on the second hand market waxes and wanes depending on what is happening with spare parts availability, or the expectations of spare parts availability in the future.
  4. I would reuse that piston and if the ring end gap is still OK, reuse the rings. For the little end bearing, do a visual inspection on the rollers, the pin and inside the conrod hole with a magnifying glass. If it all looks OK, reuse them too. You will find that trials two strokes running modern oils gum up the rings at an alarming rate, especially if there is too much oil in the fuel.
  5. Maybe they are good storage container for bike parts?
  6. Yes the cable may have been damaged, making the return action (throttle being closed by the spring above the slide) sticky. Another common crash damage thing is the twistgrip tube being pushed against the end of the bars, also making the cable return sticky

    There is normally only a tiny clearance between the torque link and the pivot arm

    Post up a photo if you want to know what's up
  10. could also be cable damage
  11. You could get the seller to measure. If you can say which design cover you want I can measure some up for reference
  12. Do you mean a Yam-frame Majesty or a Godden?
  13. Set the nuts so: The pressure plate moves out parallel. There is just enough drive to kick start the motor without the clutch slipping. You can set this with the clutch cover off but the plates need to be well lubed. Stainless steel lock wire. Copper wire work hardens. Of course it would go fine for a while without wiring but do you need the stress in your life of wondering if they were going to move?
