New Indian
Big Base Scout Cylinders
Indian last made these cylinders in 1948 in a run of 50 for racers. Those cylinders have reached maximum bore limits and oversize pistons do not exist. Our new Big Base Scout engine parts are 100% made in USA. Sand cast from certified Grade 30 cast iron. We use all new programming and fixturing for absolute perfection. CNC machined on our machining centers. Larger and thicker base flange and cylinder wall than original for more strength. (No more cylinder breakage due to sleeves.) Redesigned and improved port design. Flow tested. Fits with original factory parts. Cylinders are bare and unpainted, bore finished -.003 for hone to standard, valve seats roughed in, otherwise completely machined.
