Hey Stork, RESULT !! She is now thumping like she should. You were right, Primary jet blocked. I also lowered the main jet needle one notch. Runs and ticks over like a dream. Still have a little smoke, but I am hoping that will burn off after a long run. Thanks mate, sometimes you get blinded by the "bleedin obvious" She should be good for a few months now until I get an Evo

Cheers chaps, I will pull it apart tomorrow and check out your pointers. The Exhaust drips thick black oil where the rear section meets the tail section after an hour or so running. I have cleaned out the front pipe, how do I clean the mid section, I take it replacing the packing on the rear section is the best option ?

Hiya, Dirty and black even after 10 mins on a new one

Help !!! I bought a 2002 Rev3 250 in December to go out and enjoy with my son on his Gasgas 125, had some great fun on it until now. Basically, it runs like a bag of spanners !, smokes like a BBQ and is terrible to start. It over runs when the throttle is closed, bogs down on pick up and is a pig to start when warm. It needs choke to start it in any condition. It runs very lumpy too. I have used the same fuel mix on both bikes and that has not changed, I have cleand and checked the carb and set the float arms as per the advice posted from Billy Traynor. could it be a jet problem ir a needle wear issue ? Any advice would be very welcome before I loose interest or the plot
