How to modify NSR12S3
#1
I want to modify crank-piston and sleeve of my NSR12 S3 
I imagine I have to widen the hole of the crank shaft , and also to do a chamfer (or something similar) that allows the fuel to get more easily and more faster in the combustion chamber .
It could be useful to see some photos (if someone have them) of the sleeve and the crankshaft modified (from someone who knows the matter).
I don't care about efra or other rules.
I want only to go faster!
Thank you.

thank you friends
the thread is very useful but is also too technical
for my purpose. I don't want to change too much of the characteristics of the engine.
I only want to copy
I will do some mods and then i will show some pictures on this thread.
Don't expect nothing before 2-3 weeks
P.S. IN THE MEANWHILE: IF SOMEONE
HAS SOME PICTURES OF CRANKSHAFT OR SLEEVE OR OTHER PIECES OF NSR12S3 OR SIMILAR ENGINES MODIFIED.....PLEASE SEND ME THE PHOTOS OR PUT THEM ON THIS THREAD....
UNTIL.....
IT WILL BE.....
TOO LATE

I don't copy only a photo. I have seen a lot of engine inside modified by Mario Rossi, Colombini, Fantini, Pizzamiglio....and to say the truth
I have modified my first engine at the age of 13
It was a Picco P5 - 3,5cc. 5ports. And it ran better...
.... or it seem to ran better......
So Help .... if you want

mariochi, its nice to see someone new like you take a stab at it, dont let anybody discourage you, you will most likely mess up an engine but you will only learn and at least you have some balls, those who discourage you only do so because they only fear you probably be good at it.
