Guys.......I had a chance to ride the 150 today( it's my sons) and wanted to provide some feedback. First off I did the needle jet adjustment (dropped it two notches) that 2manytoys suggested and it did clear up what seems to be a flat spot in the power band. I was really surprised at how good this quad runs on the bottom end. The suspension works great and seems to be spot on as far as the setup goes. I'm not dissapointed in the top end but it does seem to have something keeping it from running better (I think it's in the stock clutching) and I will take a look at that later. This thing has too wide of a turning radius for my liking so I'm going to look into grinding those stops down a bit to get it to turn sharper. The gas cap did not have a vent hole in it so I put one in it myself. I'm wondering why the swing arm does not have a grease zerk on it??????anybody know? Also, you have to have the lights turned on to get it to start??? not sure why. This machines could use a foot break and a kick starter. Time will tell just how good this machine is but I think it's a great value for the money.

 

Sounds like you have had to do most of what alot of us had to do to our 150 also!
