YS115
Displacement 18.73cc
Bore 30.4mm
Stroke 25.8mm
Weight 730g

OS 120 Pumper: - $465
Bore: 30.4mm (1.20")
Weight-With Muffler: 35.3oz (1000g)

OS110 pumper - $480
Bore: 1.20" (30.4mm)
Stroke: 0.98" (24.8mm)
Weight: 21.5oz (610g)
Muffler Weight: 2.5oz (72g)

Tuff choice. The os110 weighs less than the YS115. The os120 swing the same prop as the YS110. I think the os120 would be too heavy. I would check the Focus Sport thread to see if anyone is using an OS120 or OS110. There is only a $15 difference in price.
