  1. Inmotion as already mentioned or try Kevin Breedon Racing he supplied me with a 349 piston last year. millers may also be able to help.

    And please note most suppliers stock more than is shown on their websites!

  2. The number should be the same as the frame. The casing have other numbers that are matching numbers as the cases where graded in the factory and matched together then have the same number stamped on the two halfs of the case. These numbers are usually on the engine mounting lugs and usually are a two digit number.

  3. I have looked at a mh 200 front wheel I have it has no spacer between the brake plate and the fork it has a10mmish spacer between the bearing and the speedo drive and no other spacers The end of the wheel spindle does poke through the fork leg to get the forks parallel though about 4mm so Mabee it has lost the 4 mm spacer in time.

  4. The fork tube can be level or dropped through say 6-10mm, this will sharpen up the steering as long as the forks dont hit the bottom of the bottom yoke. I run my MH349 with the forks pushed through 6mm but the cota 200 is level (I havent played about with it yet!). The 200 turnes a bit better than the 349 mainly because its shorter as the forks seem to be about the same angle.

    Im quite impressed with the 200 Im pushing 18 stone and it will drag me around most sections the little motor is impressive pulling really well for only 175cc, I havent road a TY175 for some time but the cota seems more lively but still has the ability to plod when required.

  5. Ok been doing a bit of research and my carb isn't the correct carb unless anyone can tell me otherwise. The carb has 2 screws holding both the top of the slide and the float bowl and looking at the online manuals it should have a top similar to a mk2 and the bowl should be held on with a wire clip.....anyone ?

  6. iam coming up with 38

    Well that would answer my question then as the 25 will be way too small. I better check the others too if you know them as Im starting to think this carb may be off another bike. Although it does run very well.

    According to my mh123/200 manual, the carb spec is as follows :-

    Make - Amal 6264/402

    Diffuser diameter - 24mm

    Main jet - 135

    Low speed jet - 20

    Gas valve - 3

    Sprayer - 106

    Needle - 4a (2B1)

    Hope this helps

    thanks for the info but my bike has the earler MK1.5 carb and your is a MK2 so the jetting will be different,

  8. Does anyone know the idle jet size for this bike? please, I cant get mine to run right without the mixture screw right in even after prelonged attempts of cleaning the jet. Mine has a 25 fitted at present.

    Thanks in advance.
