Want to try 10hp trike..
Bored with my HS49, no gears just two sprockets. It works as a top speed adder at best. Does stay fast but takes a while to build up speed.
I was thinking of getting a big horizontal Honda engine and mount it on the back of the trike and go from there.
I dont think i would attract much police attention as long as the trike was narrow and stayed under the speed of traffic. I dont want to be passing everyone lol
