    Hang on guys, aren't we getting a bit ahead of ourselves? The radiator cap is only a guess and you'd be much better to check other aspects such as the hoses before buying a cap.

    In my experience modern radiator caps rarely fail. Not much to go wrong.

    Its more likely to be a tiny air leak, possibly at a connection point.

    Apart from that, I agree that Supercheap etc is a perfectly good place to source stuff.

    My apologies, I didn't realise you could click on the different categories

    Yes that is true but I am currently preparing for the final exams of my degree and don't think I am really confident enough to start pulling big parts of my bike off by myself (which is required to get to the hose between the radiator and overflow) so if I can get a replacement cap for say $20-$30 I would take that as a first alternative

    Genuine Honda (car) radiator cap is $20.41 through Honda and appears to be identical. I'll take one home tonight and check against my VTR and let you know. Would be a cheap thing to try for a start

    Sorry just clicked you're talkin 250 when I've got thou. Did a little research and they are different. Does sound like possibly a cap issue, loses coolant around there so the resevoir level doesn't change because no pressure to allow push/suck coolant to the overflow. Or as said before possible blockage of the resevoir hose, although this would be pretty unusual. Maybe more likely it has been kinked than blocked. I'd be inclined to try a cap first to see if that fixes it. Would definitely rec a new one rather than used though as who knows how good a used one is - if you still have the same problem do you know the cap is OK or just as faulty as the old one maybe? Depends on the price of course though.

    Sorry couldn't be more help - good luck

    thanks for the suggestion anyway. From my research it is the same cap as the cbr600rr but I'm unsure what other models

    Finally managed to get a new radiator cap and it hasn't fixed the problem. $50 wasted
    So now, next step is to replace the overflow hose. Sigh, the manual calls for removing one of the carbs

    Could be to much air in the system, have you tried bleeding it. Should be a bolt or something for this. I know on my bike you have to bleed the system when changing the fluid, maybe this wasn't done. Just guessing here, I'm no expert.

    Will have to look into that. I have heard of "burping" the system, but never bleeding in terms of the cooling system. I still think air is getting in somehow or that there is some debris moving about and blocking the hose though cause it doesn't really have any of the symptoms of too much air in the system. At least it is one thing I can try again though. Thanks

    probably this question has been asked--but you aren't filling the overflow up to the top are you?

    Nah, I am not touching the overflow. I am filling it straight at the radiator cap because when I check there is no coolant visible there

    Are you ensuring the overflow is full to at least the low level line and are you burping the system? (getting the air out of the system

    Yeah the overflow is very full to the point that coolant gets pushed out of the overflow reservoir and pushed out the back through the hose. I have only just learned about burping so will try it

    Not burping can't have been the whole issue though as surely the mechanics I took it to would have known to burp it when they put the coolant in
