WD 40 will compound the problem. It is only a water dispersant. It will leave residues.

Gliderguy100- the 'dimples' that you are seeing are probably the lubrication holes drilled in the connecting rod ends for the bushings. There are no grooves on the crankpin. It is just a polished press fit piece. The connecting rods that I've seen have a chamfer.

Also, you mentioned interest in having a 46 sized engine. The upgrade on the Alpha is a 46 crankshaft, and a 46 piston/liner set. The cylinder head will still have the Alpha symbol, but that will be the only difference in the two engines. It would be worth doing if you ever had something eat up your piston and liner that caused you to buy parts. Evolution parts are cheap.
