katana 1100 1981 model oil cooler

[2or4strokes]

Hi Guys

Need some help from those in the know. I just fitted an oil cooler on my bike and and found that the oil cannot flow up the oilways to the cooler. I routed the oil from the base of the engine in front where there are 2 stud holes and even routed it the right way. It seems that the oil cannot generate enough pressure to go up all the way to the oil cooler.Is there some kind of one way valve that has to be fitted ? Any ideas why this is so?

You need a restrictor to divert the oil to the cooler:

Many of us like to add an oil cooler to the big Kats to try and keep them comfortable. What many off you probably don't know and I didn't either for some time is that unless you change the oil filter cover the cooler is little more than cosmetic.The reason for this is that the 1150 oil filter cover has a restrictor in it to force oil up the oil gallery to the cooler. Without this cover little oil gets up to the cooler.WARNING - if you ever remove the cooler also replace the filter cover with the stock Katana cover or you will turn the engine into a boat anchor.

As mentioned by exc911ence, find yourself a GS1150 oil filter cover, and you will be all set. I have found one for my 1980 GS1100ET.
You can search for these on Ebay, or on Suzuki GS forums.
