  1. is there anyway to stop the annoying clutch rattle on the gas gas?

    ive been told its normal and nothing that can be done, rattles on idle with clutch out, as soon as you pull it in it stops...

    anyone?

    no thats just how they are, they all do it

  2. Billy,

    It's down angular momentum. The higher the rotating mass, the higher the rotation speed and the greater that mass is away from its axis, the more angular momentum there is in the engine. This translates to the bike being harder to deflect from its current direction and hence feeling heavier.

    Whilst the difference in overall weight of a 125 to a 250/280/300 is small, most of that weight difference rotates, i.e. the piston, con rod, crank & flywheel. Also the fact that a larger engine has a larger stroke increases its angular momentum & explains why a 225 (short stroke) will feel lighter than a 250 (long stroke) despite a small difference in engine size and overall weight.

    Regarding the future Trial 125 4-stroke. It has a relatively high rotating mass (there are lots more bits spinning round in a 4 stroke than a 2 stroke) plus as a sleeved down 250 it has a relatively long stroke, the same as the 250, & hence the crank, piston & con rod mass is spinning further away from its axis than in a 125 with a short stroke. Both of these factors increase angular momentum & hence the feeling that the bike is heavier when turning or moving it around.

  3. Hi try Simon at Kelcote in Leek, he has loads of second hand gas gas pro bash plates. 01538 383547. He is a top man and will help you out with most bits as he has one or two pro s the he is breaking.

  4. Hi all

    Am I going a little mental here?

    Seen home page of website saying giant TV Screen at Sheffield.

    I am pretty sure that we were expecting a screen there last time round as well... So should we actually expect one this year??

    PS: I am not dreaming am I? There was one due last time round wasn't there?? :hyper:

    HI no your not going mental, they did promise one last year but there was no show. somthing to do with technical problems?

  5. Hi This is completly normal for a gas gas. Its the clutch that rattles,dont worry about it they all do it. Ive had mine nearly five years and never had any problems, just go out and enjoy, brilliant bikes!

  6. The front brake on my 07 is stock and it squeals so loud I need to wear ear plugs to ride! So far I have tried draging the brake until hot and then quenching it with water (per Ryan Young's suggestion), and sanding down the pads. Nothing has helped at all! Anyone have any suggestions???
    I HAD THE SAME PROBLEM WITH MY BACK BRAKE TURNED OUT, IT WAS LEAKING FLUID, REPLACED SEALS, CLEANED DISC WITH BRAKE CLEANER AND FITTED A SET OF D.P. PADS. WORKS BRILLIANT NOW - NO SQUEALING. GOOD LUCK.
