Have a large list of repairs to do this Winter.
Finally found a vintage aftermarket "Derale" oil cooler which hopefully will fit the sidecar rig.
Cooler was listed for $80.00 + shipping on EBay....no takers and it continually dropped in price until it was offered for $30.00 Total, shipping included. Couldn't pass that deal up.
UPDATE: After some research I found some facts concerning this particular cooler set up. The design led to some failed engines and were known "in the day" to be a piece of crap. Tom Cutter stated that many people who installed this cooler soon became "pedestrians"....lol...$30.00 "down the drain" I guess. Won't be installing it.
I'm glad I reached out for others experiences prior to using this.
Been running the side hack with only the "Brielle" oil pan cooler. It's cooling effectiveness is marginal at best. Plus it has developed leaks around the gaskets. I'll renew both gaskets this winter while I have the bike pulled apart.
