huge

Hi all. New member, rider and mt07 owner. In 3 days I've put 270 miles on the clock and have a sore bum but huge smile! Now just waiting to break the engine in to find out what she'll do in the higher revs.

Does anyone have any experience with sprocket ratio modifications. There's a 16/43 ratio combo available on eBay. I don't even know the original ratio but would be interested in any comments. We have rediculously low speed limits in Oz and huge speeding fines but they haven't figured out a way...
