bought the wife and I 2 new linhai 400 4x4 quads several months ago.so far i love them.have about 150 miles on mine. go pretty much anywhere i point it. is there any known mods for a little more power that dont cost much?i just moved to laramie wyoming and have already found a few places that are pretty fun to ride.

 

Nobody has anything? I guess I will start with the emissions stuff.
