Congrats on the new bike :)
I nstalled a FMF Fatty w/a Turbine Core too Silencer, made a big improvement, bike pulls hard and has more top-end power.. Then i installed a set of Moto Tassanari reeds and noticed an improvement.. I went down one size on the mainjet (I would have too look in my notes too see what the carb is set at) the bike has been on the same spark plug for over a year and i ride just about every weekend, except during the summer this past year.. As for the suspension, i would play around w/the clickers, the susp, if stock, should be close for your weight.. May want too put new oil.. Also, i use Maxima 80wt in the gearbox, change it about every othe ride.. Im still on the original clutch.. Have fun on your bike :thumb:
