For my senior design project I am designing an electric go kart. I figured why not build to directly compare to an existing class.
I was trying to find what kind of HP a normal 125cc engine puts out. I have found some of those $4000, 35 HP engines, but do they meet the class rules? or are they "road race" engines.....
Moto: Engines must be mass-produced, single cylinder,
motocross motorcycle engines up to 125cc displacement and
of the current year’s production or older. No prototype, preproduction,
“works type motors,” or road race engines are
allowed. Engines may be liquid or air-cooled. Induction may be
piston port or case reed type only. OE parts can be interchanged
from any year model of the same brand name and
similar model of motor (i.e., CR to CR, YZ to YZ, etc.), provided
that these parts are normally commercially available
over the counter in the USA to all competitors.
What is the typical and even best per rules engine power and cost? What is the "class standard"?
