Thanks all...yes, the Predator 99 it sounds like a winner, what do you believe the HP rating to be?
So why do you need the Q-matic?
I have been building recumbents for over 20 years, my favorites are tadpole trikes, but I have been getting into the 4 wheel bikes,
I bought this one the other day that looks a lot like the old Briggs and stratton 5 wheeler,
the 5th drive wheel is like a trailer in back, it had an engine in the side, I want to do something like that seems the predator 99 would be a hot ticket,
I have to wonder how heavy the B&S design was, I am guessing the engine and drive parts would be more than the new predator 99,
My plan was to use the rear swing arm from a discarded mountain bike, it will give me a nice looking frame, and pivot,
But I planned to just use a clutch on the engine to a large sprocket on the side of the wheel, I know from my go kart and mini bike days that is good from take off to...??? well, faster than I want to go on this thing,
Which brings me back to why the extra Q-matic thing?
