I have heavily modified my engine.Different crank different cams and some other parts have been changed out as well.
I originally was going to fit a 55mm system to the bike but was told by someone with a lot more knowledge than me that if i was going to modify the engine there was no point in fitting a 55mm system as this would restrict any other mods.I needed to change to a 60mm system to get any real benefits of the engine work.
I don't think i would go down the modifying route again because there were so many extra costs involved it got scary.
Also the other thing to think about is the fact that my bike now needs to be warm before it will tick over and it is absolutely useless at anything below 40mph.So if you want to use the bike on the road my advice would be to maybe change the Flywheel and fit a slipper clutch.Other than that leave it standard.
