not quite sure but it could be part of the carb heater relay if your 600 has it, i have a similar thing on my 900. i expect someone else may come along and give you a better answer or you could buy a Haynes manual.

I can't make out what it is. Maybe something retrofitted into one of the carb balancing vacuum 'holes'? Here's the diagram for later bikes, can you see it on that or offer more info on where we're looking? www.ashdownsailing.org.uk/MLH/xj600-1998.pdfPage 11. Failing that Reaper will know. |

Pretty sure that is the carb heater (if it's on number 4 carb - RHS as you sit on the bike.)

Aah! It's the sensor, not the heater itself. Deffo'. I reckon. Looked at Haynes - sounds spot on.

Mind you - I would suspect the general fueling is really the problem here, rather than carb heating.
Choke working OK? Bike left on side-stand? All the usual stuff before suspecting this heater system.

Just a thought but have you checked the tank for water. My 600 although ok to start when cold, I was having trouble starting it hot, problems getting the fuel through. There was water in the tank. Got it out and it starts perfectly every time now. Anybody would think that it used to live in the Lake District  |

When you say running klike a dog, what sort of revs are you having trouble at ?
There are three fuelling circuits in a carb - and all can be affected by overly rich or lean mixtures.

right a wee update. Started it this morning and it runns rough but when heats up its ok?. The brass think on the carbs has 2 wires on it and im gonna test to see if any feed from it. I know its oil heated coz i see the pipe from the cyinder . One of the down pipes was glowing red when it was ticking over. Just one of them. The rev range thats its rough at is all of it till its hot. It seems as if its running on 2 or 3 cyl ??. it just seems to have no revs till heated. Im gonna get new plugd and leads just to try it . Only time i seen down pipes go red was with wrong sparks installed .

Don't run the bike anymore Mark. Red hot downpipe is not by any means normal.
I wonder when the valve clearences were last done? Maybe an inlet valve is burning out and always slightly open. Possibly thermanl expansion closes it better once cold.

Thta pipe that's glowing is obviously oveheating quite nastily, and may well be running massively lean.

I tend to agree with GM = sounds like you're running very weak on the pot with a hot pipe - Check fuel level in the carbs is set right and all are the same (adjustment is easily knocked out when cleaning out float chambers) & make sure the main carb slides all raise & fall in a similar way. ( If the guilty carb slide is sticking down the needle won't meter the fuel to match the air volume - resulting in it running lean & that can quicklty lead to a knackered engine. Remember rich mixture = safe cool burn.  Lean mix = hot burn & damage!  |
