As the guys have said..
Front down to a 16, they are geared high anyway,
Get the bouncy bits sorted, got to be someone near where u live that knows what there doing.
Sort the spongy brakes sorted out... and yer nissins, cause they dont fade like the toks... and no im not getting into this

Get rid of the side stand, it drags everywhere, and takes a couple of KGs off
Rearsets if lean a bit, stock pegs drag everywhere again, gumbys dont have a lot of ground clearence.
Im 6ft3 myself and find the cockpit a tad small, but i fitted fully adjustable rearsets and run them all the way back and one hole down, and they still touch at turn 1 at broady. thats about all i can think of at the moment.
