[redtrummy]

Thanks again R1ff, I have removed the carbs ready to take a look. I thought it would be a sod of a job, they have never been stripped down since new but all the screws came undone A1 ok. Has anyone any info on checking the float height? I did have the manual downloaded on an earlier computer but that went kuput. I found where it said standard was 7mm but that was all. Think the obvious and likely cause is a float needle with gunge stopping it sealing. Ashamed to say the bike has still less than 9k on the clock - never really get much time to ride it but when I do I always come back brighter than when I set off (assuming its running ok)
