fzr 600 cutting out at hi speed
john bartlett said 2011-08-11 08:33
right iv got an fzr 600 4JH when i open the throttle nice and smooth it pulls fine. But if i shut it of around 80 it splutters and cuts out and wont pull. if your gentle opening the throttle it will pull through it.Iv checked every thing i can think of even had it to get dyno jetted and they could not find any thing wrong. The carbs ar set up fine its had new carb rubbers and a good carb overall nothing wrong there either and balanced. it had a full micron system on so i changed the down pipes for stock ones and its still the same.new plugs caps leads. it is streetfightered and the rev counter goes up and down on its own possibly a bad earth. it seems like its wind related because it didnĀ“t splutter or try to cut out when it was on the dyno.?????im getting to the end of the road with things to try so any help would be much appreciated.THANX JOHN
