Post by: mcyoungy on 16 May 2012, 05:43:34 pm: cracked carb rubbers will make it run lean, not rich

Post by: red98 on 16 May 2012, 06:20:02 pm: cracked inlet rubbers are a common fault on 600 fazers,they are very thick and its a fair bet that there not cracked all the way through.and as MCYOUNGY has already said will make the bike run lean not rich :)

Post by: bikemad62 on 17 May 2012, 02:17:45 pm: Take the choke plungers out and get a magnifing glass and look at the rubber seal faces for wear or cracks. just because they move don't mean they "ain't" damaged !!!!

There are a surprising amount of moving parts in there. and always use a magnifying glass. The damage may be hard to see with the naked eye. My son had a small split in one of his slider diaphram and neither of us saw it until i magnified it. caused all sorts of problems. hope this helps.

Post by: Gnasher on 18 May 2012, 01:38:39 pm: Is it rich at idle and below 3k or above 3k?
Title: Re: running richhi
Post by: bikemad62 on 21 May 2012, 09:06:18 pm: Get a haynes manual for a start. If the needles on the sliders are worn they will let more petrol through and that may cause the rich mixture.
