I have a sweet 2010 four valve 1200 Sport (low mileage, one previous owner) and it's up for rollerising. Basically this will be a C kit job, and I have a mechanic who has done this before, with the work-around that makes it slightly less expensive. However I believe a re-map is also required once this is done, and if I remember forum discussion, the factory remap is not well thought of. So this seems like a good chance to buy Beetle's version (the GuzziDiag settings?) if you have them for this model. (Most discussion, naturally enough, is on Grisos.) I'm in central Scotland, so UK or local experience would be relevant, plus any other advice or suggestions along with the links and info that will make a download possible.
