Im 196 lbs, mich street rear tire at 20 lbs, mapped for K&N and yoshi slip on, 17k on bike, plugs are about 3 months old.
1**for your weight, i think you might need a little more gearing to get your 60fts down, but you can try #5 first.
2**tire choice, i'd go with a 190 shinko u-soft @ 20psi or so. it's cheap, it's heavy, but it works.
3**as far as the mapping, was it custom mapped on a dyno or was the map simply downloaded? if downloaded, you may want to get the bike custom mapped. a lot of times those downloaded maps run on the richer side.
4**plugs will probably be fine, but if you aren't using NGK cr9eix iridiums, you may want to give them a try.
5**other tips: save as much weight as possible and make sure you only run enough gas to keep the fuel pump sufficiently covered. 1.1 gallons or a little less is what i usually run. as long as the gas light is flashing you're good to go! i found that the difference between running 1.1 gallons vs 3 gallons of fuel was about 1-tenth off my 60ft.
be sure to stage at least around 6500rpm. some heavier guys tend to stage higher, lighter guys probably stage lower.
