    So I decided to get back into the small capacity 4 four cylinders after vowing never to buy one again after I sold my MC19, so I managed to swap one of my cars for 3 88 fzr250's. 2 of them run and the 3rd is cactus which is a shame because its an EXUP model. I've already sent one of the motors to be reconditioned and the frame is going off to get power coated next week. I've been riding the other around and have noticed it's starting to get fairly hot I live out in rural South Australia so it's always hot here no matter the season is there anyway I can improve the cooling system my engine builder can fab up a slightly larger radiator for a couple hundred or I could fit a bigger one from a different bike? Will be updating this tread regularly throughout the resto may help a few people out with there own projects USER_SCOPED_TEMP_DATA_MSGR_PHOTO_FOR_UPLOAD_1546255673299.jpg_1546255675539.jpeg USER_SCOPED_TEMP_DATA_MSGR_PHOTO_FOR_UPLOAD_1546835434343.jpg_1546835438874.jpeg USER_SCOPED_TEMP_DATA_MSGR_PHOTO_FOR_UPLOAD_1546835402756.jpg_1546835406928.jpeg

    Welcome. You've come to the right website/forum if you own an FZR...this site is littered with knowledge on these bikes. Maybe turn the 3rd bike into a track bike or drag bike when you finish your current project.

    The radiator is very clean inside and I did I quick pressure test properly be worth getting the fins straightened out though I double checked the fan and yeah it does work fine but I recon it's spinning a little slow.

    Thank you Frankster I would turn the 3rd one into a track bike but I wouldn't even sit on the thing is a proper potato and it's been binned Lord knows how many times but it does have some real good parts eg. Suspension, wheel, loom, ect, ect

    Thanks GreyImport I wasn't sure if I should get the concentrate or the pre mix

    Pretty sure that the thermostat housing just uses a large, regular shaped O-ring,
    from memory. Maybe buy a few different sizes and test the fit? Should be cheap enough.

    That would explain why I can't find a thermostat housing gasket

    I have had no problems with anything I have bought from them so far. Postage time is around 2-3 weeks.
