i've got my 600 project running well on choke but once the chokes off she runs rough & backfires - alot. She also revs up fine, the trouble starts when the throttle is released? I think its the carb thats playing up but thought you guys may know whats causing it. thanks Dee

obviously a lean condition... I would check for plugged up jets
did you use a carb sync tool?? when doing mulitipul carbs you really need to have them synced up correctly or all kinds odd syptoms will come about.

thanks for replying, its a carb i've not seen before plus i'm running an elecric pump http://www.srx600.f2s.com/srx600/technical/gen_spec/genspec6.php
so you reckon the backfiring is cause its running lean - i'll whip it back off 2moro & pull it to bits, again...
