project: is turning a CRF 80F into 125 or more doable?

Hi, I'm 5'1 and although I am able to ride trail bikes fine without flatfooting (CRF230 or XL125), I would actually like to know if technically, it would be possible to take one more suited to my frame (and I don't just mean the seat height, I mean the bike length, frame, distance of handlebars etc etc) and give more it decent power (125, 175 or 250?) without completely screwing up the bike's integrity. I understand it may lead to changing other parts than the engine such as breaks etc etc..

Frames for several 80cc are ideal. I stress I'm not looking for advice on how to ride a tall bike, let's say this is a project so that I can have shoes taylored to me rather than running around in my mum's. I keep meeting ladies who would love smaller frame trail bikes.

Any ideas you have would be great, then all I have to do is find someone who wants to take on that kind of a project.



PS: for those who like tinkering with cars too, my uncle stuck a BMW engine in that: http://bit.ly/1aorzem and I still laugh thinking of the faces of other drivers when we whizzed past them on the motorway!!!

So long as there is the clearance in the frame for the engine to actually fit in the space I don't see why not..... 8-) Obviously you'd need to make or get made engine mounting plates.....and then mess around making sure that the chain run is straight to the rear wheel.....but everything is possible..... :wink:
