With the cylinders 3.5 inches in bore and the pistons 3.15 inches in stroke, the engine compresses air at a ratio of 8.4:1. The FX1000V can produce up to 56 pounds-feet of torque and features a pressurized lubrication system, electronic spark ignition and automatic compression release.

With a slightly smaller displacement capacity at 726 cubic inches, the FS730V-EFI produces up to 25.5 horsepower at 3,600 rpm. Also featuring a pressurized lubrication system, the engine is capable of producing up to 40 pounds-feet of torque at 2,400 rpm. It has a compression ratio of 8.2:1.

The smallest of the three, the FR541V produces 15 horsepower at 3,600 rpm and 31.7 pounds-feet of torque at 2,000 rpm. The engine displaces 603 cubic inches of air at a compression ratio of 8.1:1 and holds up to 1.7 liters of oil.
