you need to go to St Roch De L'achigant
and Pointe du Lac
, it is betwen Montreal and Tree Riviere about 20/35 min pass Montreal, the Karts are 9.5 hp , they eaven have winter karts ! the engine are not lock , they are wide open , they are real race kart chasi , and the tires are real race tires ( slicks ), the tires will put the kart on 2 wheel if you go in the curv to hot and dont let go a bit of the fuel , the track is outside and they have real week-end event there , in that neck of the wood karting is like soccer in Europe .
if you have the balls and the $$ for it they rent 80cc 2cycle kart and dont forget the 125 shifter kart ( iI think that you need licence for that one )
hope it will help you
