After two years of head scratching, I think this is the easiest way to adapt an oil cooler to this engine. Reclock the filter cover, and tap the cases for 1/4"npt

Thought I'd share this observation here for interested parties. The late model connecting rods are a much more refined design, bigger and smoother radii everywhere. It may not seem like much but these details make for a significantly stronger rod.

Perhaps the oil is cooled by spraying it all over the transmission case and letting the breeze take the heat away. A large hole in the top of the case will let the cooled oil drop back into the sump where the pump can pick it up again.
Brilliant engeneering, I say :silly:

Gives new meaning to air/oil cooled!
I actually cracked the edge of that cover trying to hold it in a vise so i had to make some wooden jaws to hold it. The existing holes are already perfectly sized for a 1/4"NPT tap. I used 1/4npt -8 AN fittings. I got steel fittings so I could drill out the 1/4" NPT side to match the 8AN diameter without loosing strength.

Saving up money for this engine build has been taking a long time. Race parts are not cheap
I have been distracted by this '86 GSXR750. It now has Bandit 1200 power! custom aluminum tail by myself.
