Get a pair of boots with the thickest soles possible, you can also add lifts, but try the lifts in the boots. With boots and lifts you can gain 2"" in height. You can also drop the front forks through the triple trees by 1/2". You could go more but you may encounter handling quirks and difficulty putting the bike on the centre stand. Same problem with adding a shorter rear shock which can be sourced. You can also get the stock seat shaved by an upholsterer that knows what he is doing. Or finally get a low seat.
