Non Micra help please

[wehey]

Hiya all. Sorry to post non Micra related stuff but this is the best site I have come across for advice.
Anyway, I have another project on the go. I have an old Honda C90 step through motorbike which I am restoring. Part of the plan is to install a 108cc barrel/cylinder which will boost performance. To do this I have to get the crankcases milled out by about 4mm to take the larger piston as in this video.

The problem is that I can't find any local companies who want to take on a one off job like this.
I know there are many of you who prefer the home/ghetto/DIY route and I think that this could be done at home with the right tools and I have heard of people doing this.
So how could it be done with basic tools?? I'm thinking a dremel with a milling bit and a flap wheel.
What do you all think? Any advice would be much appreciated

i would use a milling bit in a drill wehey, and clean it up with the flapwheel like you say eh

i have a bit with about 12 straight flutes wehey, but it tends to clog on alloy (cuts well tho) a 6 or 8 fluted one would probably clog less eh

So something like this http://www.amazon.co.uk/Straight-Sh...=sr_1_69?s=diy&ie=UTF8&qid=1354302108&sr=1-69
Just put it in a hand drill, clamp the cases down and go at it???

o so ya be a mature man haha

ya may not get the same quality finish with a drill and mill cutters, as the inner wall of the cylinder may cause were on ur pistons

so if the project means much to u i recomend search for some cnc machine workers to do it for u shouldnt cost u much

I wouldn't do that personally. I had some done by carward engineering, his website has disappeared though. I'll PM you his number if I can find it.

these are mine mate, the 1st one never clogs but leaves a lot of chatter, the others cut cleaner but tend to clog on the soft alloy
