    Welcome to the forum. List any mods done to the ski. Has the cat con been replaced with a D plate? Also, how many hours on the ski, need more info, compression good, plugs replaced?

    Hi its got the D plate, riva free flow exhaust, power filter & chip as far as i am aware engine wise. Only just bought it with the fault. 85hours but has had a full engine rebuild last year. 130psi each cylinder any good?

    ...did the ecu code check and it come up 01 so looks like sensors all ok.

    So what else it starts first time, idles the give it a handful of throttle and it flat spots big time?

    PLEASE!
