Oil cooler

[curlyjoe]

The "13 service manual has an oil flow diagram on page 4-2. It looks as though there is a 2 chambered oil pump where one chamber pumps through the oil filter and into the lower engine (cylinders and below). The other chamber pumps oil into the cooler and from the cooler, into cylinder head channels around the spark plugs. From the cylinder head it flows through a channel with the EOT (engine oil temperature) sensor and then back into the sump. This design is consistent with the Honda engineers worry about high temperatures surrounding the spark plugs.

There is a high temp "idiot" light that comes on when the oil temp is too high. I wonder if our friends in Arizona or OZ have ever seen this come on when riding in stop and go traffic on very hot summer days?

You could try removing the cooler (I'm not recommending this) and then monitor the high temp light to come on under a variety of riding conditions like Pterodactyl suggested. A temp gauge would be more useful. Does anyone know of a gauge that can be wired into the EOT sensor?

Personally I don't have a problem with the looks of the cooler but as others have mentioned there are alternatives out there.

Earl's has a nice line of coolers that are designed to fit between the forks (2 different widths, curved vs straight, and variations in the number of "rows"). Mounting the coolers between the forks would involve moving the horns and also there would be a potential problem with the brake lines being just behind the cooler.

Japan webike sells [url=http://japan.webike.net/products/21220082.html]Earls oil cooling kits designed for the CB750, CB900 and CB1000F. They are pricey though and you may be better off ordering the parts directly from Earls [url=http://www.earls.co.uk/earls100/earls_shop/index.php?main_page=index&cPath=14_38&zenid=32051fs1tutjtkm9711rapdke0](link).
