    When I short shift into 4th and throttle hard it occasionally slips back to third. It is a WR250F.

    Does anyone have any idea as to the cause as it does not happen in any other gear and it is fine if I nurse the shift but that does not always happen on the little 250:)

    Cheers

    I have read somewhere about shift issues but I thought it was the WR450, I think one of the Smith’s bikes at Yellow Mountain did the same thing and then loose 4th gear completely and Condo 750

    The WR’s had a heap of gearbox failures out there in those races until they fitted cushion drive hubs, that stopped the gearbox failures ( Crash and I have spoken about it many a time being Honda riders )

    Sorry STM but it rings a bell just cant remember if its 450’s or 250’s, but I know its a Yamaha thing I read or saw I will ask Crash

    Is this a repair to the 4th or the whole box? I am not near Tamworth but could ship it out.
