help on 440

[veddersbetter]

Im tradin my 2001 Warrior for a 2000 400 EX with a Yosh RS3 and 440 Big Bore kit. The dealer said that was the only thing done to it besides mild jetting......Is this something commonly done with the 400?...I mean..put a BB kit on it with nothing else? And if so would it mean any problems?

Its done all the time but your not going to get MAX hp with out a higher compression piston and a cam maybe some porting. All that will really wake up a 440. Thats what I have a it runs real strong. Its for sale if you know anybody $5300 ereed@loomisfargo.com

PAT, Why are you selling your 440? Didn't you just finish it? Mike.
