how much faster or better is a 440

how much faster or better is a 440 than a 400 how much did you pay to get it to a 440 do u need to run any special gas or oil or what how much slower is a 440 that a 450r

what about a 416

[cals400ex]

the 416 will be easier, cheaper, and will provide similar power. i would go with the 416.

if u build the 416 or the 440 they cant both be faster then the 450r it all comes down to the rider.....


in a drag 440 vs. stock 450r the 440 will win

how close would it be between a yfz and a 416 or 440 because my friend has a yfz and im always gettin smoked

That makes no sense at all, there are so many factors that could be used on a 440. You could have a 440 bore with 10:1 compression with stock pipe, stock air box, stock cam, and a nicely built stock bore EX with high compression and other goodies would take it. There are just too many factors to say which is faster.

i met they can both be faster but have to be built right with atleast a 11:1 comp. and have too have a desient rider

If the motor is built correctly, the 416 will eat a 440. I like both bore's, although, I wouldn't go to a 440 unless I absolutely needed too. There are a couple of guys down here who have 460 Strokers and they are wicked fast bikes... All in all, I wouldn't bore unless you absolutely have to..

a 400ex with a bore/piston, cam, filter, carb, jets, pipe, etc will not keep up with a full piped yfz in a drag race. the yfz's are really quick. if you run 13:1 compression and dump a lot money into the bike, maybe...
