If it's still not enough power, well, then I'll get a shift kit and ex-pipe... or maybe just a new motor. This one has already given me enough trouble.
My expectations are mostly derived from this thread: http://motorbicycling.com/showthread.php?t=40141
I have a smaller sprocket and I've done a little porting and I can't even hit 30. It's not lack of fuel or anything either...
A good pipe is almost always the answer. But you can try a little experiment first if you want. MOST of the stock pipes are way too restrictive, So just yank out the baffle and ride it like ya stole it. I suggest you do this in the daytime and not 2 in the morning. The neighbors might not appreaciate a dirt bike on the street at early morning hours. I think you'll find the horsepower and top end you've been looking for. If this is the case, then like I said, a good pipe is almost always the answer. I've got a real good expansion chamber on my tadpole trike and it made all the difference in the world. I'm pretty much running a straight pipe on my cruiser (just took out the baffle) and it works alright. It's loud but it runs too good to mess with.
