 predator engine longtail 7hp to an 11hp did a bunch of mods to this predator engine. New air intake and filter, stage 3 exhaust, Valve springs, re-jet carb, new cam, billet rod and crank. I am extimating 11 but it is probable close to 12 or 13hp.

Re: predator engine longtail 7hp to an 11hp I ended up having to change from a 6.5X4 prop to a 7X5prop. I ordered a billet light weight fly wheel. All I have left is a new crank later down the road, piston, and a new carb. It sounds like a mini harley....It sounds awesome!!!
