i was wanting to put a 440 big bore kit with a white brothers mx-4 pipe a jet kit a new valve spring kit for a stage 2 hotcam and a new rear sprocket....i was wanting to know how much faster it would go???[img]i/expressions/face-icon-small-smile.gif[/img]

 

You would go about 2mph faster....but that will all depend upon your gearing, wind, velocity and of course the fuel that is being used in this particular application, [img]i/expressions/face-icon-small-wink.gif[/img]

 

I think a 440 kit is a small bore. If fitted on a DS650, you will actually go slower than stock............[img]i/expressions/face-icon-small-wink.gif[/img]

Probably not the best investment.[img]i/expressions/face-icon-small-smile.gif[/img]

 

Come on guy's !!![img]i/expressions/face-icon-small-shocked.gif[/img] well bud a 440 kit if your refering to a 400ex is a awesome differance just choose a good builder. I used to put a bass akwards whoopin on some ds's with my 440 and that was big bores too!!! [img]i/expressions/face-icon-small-wink.gif[/img] But top end will be about the same but you will get there much faster than you do now.[img]i/expressions/face-icon-small-happy.gif[/img]

 

i would b burning 93 octane feul nut im not sure of wut the gear ratio is on my 400.....wut would u recommend me doin to get more speed and power out of my 400ex?

 

OK, now we know what kind of bike your talking about....you might want to post this thread in the Honda section of this forum. You might get more answers...we are nothing but a bunch of dumb DS guys who know very little about anything, [img]i/expressions/face-icon-small-happy.gif[/img]

Nah, seriously man, I think a 416 big bore kit with a 39mm fcr or a 40mm lectron carb will get you going. Oh yeah, throw a set of hot cams in it with a jj&a aluminum drag axle on the rear and you will be eating some lunch. Go get em, big guy, [img]i/expressions/face-icon-small-wink.gif[/img]

 

Now thats the spirit choose......[img]i/expressions/face-icon-small-happy.gif[/img]

 

I knew you would like that....[img]i/expressions/face-icon-small-happy.gif[/img]

 

Oh, this is on a 400EX!.............Maybe Marky will chime in. I hear he has a really quick EX. AZSAND is the resident 400EX expert of our Bombardier forum. He can make any bike rip. Whatever he recommends, I will defer to him.[img]i/expressions/face-icon-small-wink.gif[/img]

Btw, if this is your first time to the forum,...........Welcome.[img]i/expressions/face-icon-small-smile.gif[/img] Have you posted on the Honda forum yet? They would be informative.

Good Luck![img]i/expressions/face-icon-small-smile.gif[/img]
