Adding an Oil cooler from a cb900 - part 2

  After thinking about the cooler install all winter, I decided that I needed to make a bracket to mount the cooler. I could have used zip ties to hang it, but felt like it wouldn't be mounted securely enough to not rattle around on bumpy roads. A little cutting with the angle grinder and some drilling to shape 2 pieces of steel to fit above the cross brace on the frame and trying to keep everything lined up while I apply a few tack welds to hold things in place. It didn't go quite as nicely as I had hoped since the holes in the cooler were slightly off from the nuts that I welded to the brackets. Since they were only slightly off, I widened the holes in the cooler just enough to allow the bolts to find their homes in the newly attached brackets.  I'll probably find a rubber bushing or spacer to reduce vibration but the cooler looks pretty good for now. I cut the lines to fit properly with the Dremel and a cutoff wheel to break the stainless weave and a hose cutter to cut t

Adding an Oil cooler from a cb900 - part 1

I'm not 100% sure why Honda decided that the CB900c needed an oil cooler but not the CB750c. Here's my justification for wanting to add an oil cooler to my bike: running cb900 cams I live in the South Bike has always idled differently on the hottest days it's another project There are 2 options to add oil cooling to one of these old bikes. The first option is to buy a spin on oil filter adapter with ports for oil to flow into and out of an oil cooler. The advantage of using this approach is the notion of adding brand new and possibly more technologically advanced parts. The disadvantage might be cost and full pressure flowing through the hose which might impact lubrication flowing quickly enough to the engine.  The second option is to swap the parts from a cb900 with the advantag
