  1. Another option is Electrexworld, I use their ignitions on my TY250C which uses the original flywheel & my CZ race bikes
  2. Ash, Person you need to talk to is John Lawton in Paraparaumu, send me a pm & I'll give you his details
  3. Modified a set of standard top yokes which puts the bars midway between the steering stem nut & the fork tops, improved the steering by a lot on my 250. Steering head angle had been altered in 99 to match a 99 Beta so this bike goes exactly where it is pointed Lots of other stuff done to lose weight & improve the riding experience
  4. No bigger than a 250, peak power numbers will be lower than you're used to but that doesn't tell the whole story. The bigger bore bikes have more bottom end but they become a handful once you start to get tired
  5. Send me a PM Bernie, I have a new stator like that from memory that I could possibly send to you to try when I get back from the Gold Coast next week
  6. If you had oil spurting out you've broken into the gearbox which won't affect compression. you may be able to use thread tape as a temporary fix but at some stage you'll need to split the motor & have the end of the offending hole filled up which hopefully shouldn't be a big job for a good welder
  7. That's a real mess Peter, good luck with fixing the tank. I've only ever needed to deal with metal tanks so I'll be interested to see how you get on Have you ever worked with fibreglass before? I'm about to have my first go at doing a fibreglass repair on the inner guard/airbox on the CZ sidepipe mx bike I'm restoring at the moment, I'm glad it's only rebuilding 1 of the mounting sections rather than being cosmetic or sealing a tank like you're doing
  8. The backfire as it died would suggest timing has moved to me, pull the flywheel & check the woodruff key
  9. 250 takes less technique than a 125 due to having a broader powerspread, either would be a big step up on the Scorpa 4 stroke. Can't comment on the difference between the ST & factory
  10. The 250c I ride occasionally had the steering head angle modified around 99 to the same angle as the Beta of the same year by the New Zealand Beta importer's son, we stood both bikes side by side last year which confirmed what we suspected. Even with the newly lengthened swingarm this bike steers really well, as a bonus ground clearance is slightly increased without going to the extent of lifting the motor in the frame like Majesty did Weight is more of a problem on the more common A models than the later bikes with their steel tanks & bulbous aluminium clutch & ignition covers, I haven't looked for the claimed weight difference between an A & C or later bike but the aluminium tank & narrower magnesium sidecovers I would think there would have to be 2kg saved Like everything not every bike suits everyone, what works for me could be totally wrong for you. Once you've decided on how important parts supply is to you it's best to try as many of the remaining options as possible, it's no good buying a bike that is easy to get parts for if you don't get on with it
  11. It's a feel thing adjusting taper roller bearings. Adjust them so there is a slight amount of drag with the top yoke off, when everything is tightened back up the wheel should stay pointing straight until given a light push but shouldn't take any real effort to move
  12. Double check the numbers, I suspect they will actually be ST25. Without looking at my bike I don't think there are any numbers on the cylinder & head to give you the engine size, the 250 & 290 share everything but the piston, cylinder & head so the engine number isn't the only a sure indicator of actual size

    Levers.

    I use those on my CZ vmx bike, only the brake is drilled for span adjustment
  14. To use the DLS brake plate you really need to be using a 80/81 465 brake plate with mono forks otherwise the cable will be at a strange angle to the forks
  15. I have ARC folding levers on my sherco & the span is adjustable independent of the other adjustments using the bolt & locknut near the folding pivot point in visible in this photo. Some of the other folding levers may have the same feature
