    Mysterious rubber hose on GN250

    hey, i'm new to motorcycle parts and have just found that there is a little pin that smells like fuel on my GN250 which has a rubber hose connected to it.. but it is not connected to anything at the other end... is it supposed to be?

    Any help appreciated

    Breather tube? Overflow?

    Don't try putting a match close to it to help you see....

    A photo would probably assist more accurate advice....

    Thats used for topping up the compression when it gets low. You can buy cans of cylinder compression from your local dealer or supercheap auto's in differing ratios.

    That's the emergency fuel dump tube - used when circling the carpark and expecting an emergency braking procedure at any minute.

    Trucks also have them and use them on all the best twisties, but for different reasons
    They called it paradise, I don't know why.
    Call someplace paradise, kiss it goodbye.

    Where are you seeing this rubber hose? A little pin? Where is it?

    You are most likely seeing a breather hose hanging down behind the engine. It is nothing to be concerned about.

    Aha, I see you are new and some are choosing to have a laugh

    Yes it will be the breather to prevent a vaccuum (and the bike stopping).

    The best advice you have had on here is to get a manual so that you can get a good idea as to what goes where and what it does.

    Basics such as checking fluid levels and chain tension/lubrication are all fairly important.

    Good luck.
