Well, I suppose while you are in there, I'd recommend a genuine Honda piston over a Wiseco, but frankly it's probably still in great shape unless it's been motoed for 50 hours, and even then...
If you still have stock jetting...how do you even ride it? Mine wouldn't even hardly start in the garage in 35 degree temps last winter with the stock jetting! I went four sizes leaner on the pilot, which is a 25, 400 on the main jet, and leaned out the needle jet (not easy to get ahold of, otherwise just move the clip up one notch on the needle), try that jetting and see what you think. On the main you might go 410 to be safe...the bottom end was the real problem here...
