Re: 4 or 2 stroke?
either one with a large rear sprocket so it can handle the hills will probably work for you, I like the 2 stroke kits myself but if you dont know the difference between the two you should honestly do some more research before making your decision.
A 2 stroke needs oil mixed with the fuel and a 4 stroke engine has a gas tank for fuel only and th3 oil goes in the crankcase of the engine.
4 stroke bike kit 3ngin3s are more reliable for the average person and 2 stroke moto4 kits provide more top speed and more overall power for those of us who like to tinker.
hope 5his helps a little.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
