if you want to stick in 4stroke and in the cc size of 200 to 350 go with a raptor 350 nice machine and verry reliable,same engine and tranny as a warrior ,(couple differance include,more aggressive cam and diff layout in the head,better carb and better exaust for more power) and you got a better frame for better handling better break, better suspension,and its lighter!!! just my opinion,and its less expensive than a 400ex and it look better in my opinion , and alba make a perf kit thats retail for less than 500$ and with this kit you will say bye bye to 400ex for way less money than buying a 400ex !!!!
