28.5 Engine from Bartolone Racing
Bartolone Racing engines are built to perfection using specifications that have been proven time and time again. The cylinders have been CNC ported to exact timing specs and then hand finished to perfection. CNC porting assures consistency unlike some of the quick hand port jobs we've seen. Pistons have been machined for reduced mass that yields higher rpms with reduced chance of failures. Each Bartolone engine assembled and measured to precise specifications. Engines are available in 28.5, 29.5, and 30.5 cc configurations.
