280km/ph and over Posted April 3, 2009 Share Posted April 3, 2009 Some times my bike will run on all four cylinders, you turn the bike off for a few moments and restart and she'll run on three cylinders!? I have checked the CDI its in order, the coils are A okey, number (3) three carb is back firing! What can be the problem and how can I rectify this problem?

pilninggas Posted April 4, 2009 Share Posted April 4, 2009 FZR1000s are notorious for this, what you are experiencing is worn main jets in the carburettors, they go oval letting more fuel in resulting in very rich running. is the tail pipe black with soot? thats an easy way to tell. google emulsion tubes or factory pro. if you are mechnically minded you could use a workshop manual to do this job, but remember you will need to set the float heights in the carbs, syncronise the carbs as well as replacing the main jets (along with the needles). You may also have to adjust the valve clearances. check out exup1000.co.uk for extra info. Link to comment Share on other sites More sharing options...
