The stocker is pretty well rounded. I ride trails and drag for fun sometimes, and when I bought my Shee stock, it was average at best, very easy to handle and the power wasn't violent. The problem is most of the upgrades that are done to these motors increase horsepower greatly, and these bikes aren't overloaded with torque to begin with. I would use the Paul Turner Mids if you want a mid range, have a set of jugs setup with a woods port and do a 28mm pwk conversion. A lot of guys like the 2:1 carbs, I personally don't. I went the route of the T5 pipes and the power comes on similiar to a turbocharged car, I have to wait for it, but when the bike gets on the pipes it's out. Much more of a top end pipe, and hence the reason I am looking to make the switch to something to get the mid range back. Just don't try to expect this bike to behave like a four-stroke. It's nothing like any other quad out there, it's way more powerful than the competition and if your gonna try to make this into an agile bike for the woods. Remember the chassis is very old and outdated and usually not the most ideal when it comes to agility.
