400ex >>460cc big bore stroker<<

I was wondering if anyone has one of these and about the reliability, performance, of this.I am currently running a 13:1 piston in my 440. Head is done valves,springs,etc.Big carb,hmf pipe, monster cam,etc.etc. I have recently upped my 450r to a 470 and im in a stuck mode right now.i have about a bizzilion $$ in my 400 and not so much in my 450 at the moment and as finances go im just wondering.Should i try to up this to a 460(cost about 500$ or so from where im at right now) or should i dump about another 10 grand in my 450 to make it compaireable as it rides like crap and my 440 just smokes it... BUT the 400 is a dying machine as bigger and bigger bikes evolve and i still have some 450s (not many) whoopin on me.So the question...do i leave the 400 for the barn and work on the 450 and beat my chest knowing i got a fast 400 or go for the cheap upgrade and try to make it faster and sit the 450 on the bench for a bit...anyone with info on the 460 is much appreciated  

how the hell u got that much money to throw around is beyonda me but if u got money like that then well hell why not.  Then whenu get bore do it to the 450 but you should go to youtube and che8k out a kfx800 supercharged.
They are awesome power machines for dragin  

I got an 01 400ex with a 460 big bore, stage 3 hot cam. The bike has had this set up for 2 years now and i have had no problems bike fires right up everytime. This quad has amazing power and i smoke the new 450's its fun when they wanna know what the hell this 'ol bike got in it. Its just amazingly fast and reliable considering its age  

did u end up doing the mod  

my 04 es 350 rancher wont shift into any forward gear manually or by the push button but will go into reverse
