WarBird Bike is my current scratch-build, theme bike using old aircraft parts as much as possible.
Powered by a 540ci, 1942 Kinner, 5-Cyl radial aircraft engine controlled by MegaSquirt EFI......
This Kinner engine originally powered a Ryan PT-22 USN Trainer Aircraft (from the days of wood spars, dope & fabric)
Stock engine specs: 160 hp continuous at 1975 rpm (with the stock updraft carb), burns 73 octane gas, has a 5.25:1 Compression ratio, 5 inch bore, with a 5.5 inch stroke, measures 45 inches in diameter and weighs 338 lbs.
This Kinner radial engine has a couple very unusual features; there is no lube oil to the heads. Grease fittings provide lubrication to the rocker arms and push rods. And instead of a 'cam ring' (like almost all other radial engines of this period) each cylinder has its own cam shaft (so there's lots of gears inside the block to give it a very unique mechanical sound).....
