Faster than you are in bed.
I have never done this before but i think that yes! It should be fit.
Yes it can! How much work I do not know. I saw an 80 a few years back with a 125 engine in it. I just got cr80 and I'm going to put a 125 engine in it, just to play with people at the track. I'll let you know how hard it is.
