  1. always put a bit of valve grinding paste on the taper of the crank then offer up the flywheel and grind the two surfaces together until they mate perfectly then fit the woodruf key and torque it up . it is not the woodruf key thats supposed to hold it in the right place thats the job of the taper the key is only there to make sure it is correctly alligned

  2. try using that shell v power petrol and good 2 stroke but not silkolene ideally putolene ,i had exactly the same problem on a cr250 i used to own and it just about drove me daft until i was told to try this and it cured it completely and plugs lasted for ages

  3. get the plug out ,some wd40 down the bore ,turn it over for a while then make sure its sparking ,a capfull of petrol down the bore and a new plug in and kick it over and take it from there .you never know it might run like a dream .why strip down when you might not have to

  4. hydraulic oil is a great lubrication oil and will work in far higher tolerences than is required in a 4rt gearbox .think how much pressure is in a jcb hydraulic pump running at 1000s of psi for weeks on end .some people swear by atf for gearboxes what do you think that is its just a type of hydraulic oil .if the bikes all good and at decent money i wouldnt think twice about buying it

  5. hi having a bit of bother with my sons 07 125 rev 3 .its developed a really gutless flat spot just above tickover but when its reved above this its fine also wont tickover .ive cleaned the carb ,airfilter and new plug but cant think of anything else .anybody any ideas
