    SUZUKI GN250 oil cooler

    Does it make sense to install an oil cooler on the GN250? Did anyone from the forum do this? Could there be a topic in the forum? Thank you. from Serbia

    I'm sure the OP posted Serbia.

    Personnally I wouldn't bother. Just change the oil/filter on a routine basis.


    Welcome to KB by the way Bluesir. How long have you had the GN?

    No need for oil cooler on GN250, just change the oil & filter regularly.
    If the words I say offend you, imagine the ones I keep to myself...

    Basically it's difficult and not worth doing IMO. I've done it on a smaller Suzuki single for bucket racing and that was worth doing when you look at the BoB lasting 55 minutes. Pretty much an hour wide open....
    A passage in the sidecover has to be filled and oil diverted out then back in again. Not simple.
    In the bucket I also went to a larger oil pump from a bigger version as I doubted the OE pump had enough capacity.

    Std the GN250 is quite low compression with mild ignition advance - factors which should ensure long life and cool running.

    I suspect the GN250 is one of those models very like the cockroach - you can find them everywhere.

    Which is not a bad thing at all. A few years ago we came across a rather large chap doing a tour on one down in the Catlins. Loaded to the hilt he was and enjoying every bit of it.

    Sweat wipes off. Road-rash doesn't.

    If you experience high air temperatures on a regular basis, it could be a help. But unless you travel for long distances (or at a high RPM) in the heat, it really is a waste of time.

    More regular oil changes would be more practical though.
