RedDog, I have an '03, did the 28t mod over the winter. Put about 2500 miles on with the 30t. IMHO, get the 28t installed today, you will not regret it. Adds more than a handfull of power on the lower end and I have not missed a thing at the top, even the VERY top.
I put the 28T on over the last weekend and I am very happy that I did. The V-Rod 1st gear is just too tall on the 02 and 03's. You can definitely get used to it how it's geared, but it's extremely nice to be able to drive around at parking lot speeds without having to feather the clutch to keep the bike from jerking on you.
