so i trade my 86 250r for one of these 400ex with these mods:

big bore 440 wiseco piston
hotcam stage 2
edelbrock carb
full HMF exhaust
oversize oil cooler
sparks racing clutch
maier race plastic w/ carbon fiber hood
white brothers nerfs and bumper
lonestar extended axle
houser long travel +3 a arms
axis 19" triple rate long travel shocks
elka dual rate rear shock

or

curtis sparks 416 national motor over 2400 in motor
custom axis shocks
denton a arms, stering stem
lonestar axel
ac nurfs
fcr39 carb

my 250r is basically stock except for rear axle, front spacers, and nerfs. should i buy the one of these 400ex instead of fixing up my 250r. its almost time for a rebuild on my R? will i be trading down or trading up? lmk thanks

 

Are you kidding?

 

DEFINITLY GO WITH ONE OF THE 400EXS!!!!!!!!!!!!!

 

Which quad would you prefer.and as far as the motoring would you go with a 416 sparks motor or a 440 big bore wiseco.

 

I would go with a 450R instead of the 400EX. If you do get a new bike, try to keep the 250R. I guarantee you will regret letting it go later on. It's a LEGEND!!!!

 

definatly the 416 kit you will be better off with that one

 

well heres the thing im looking for an all around quad i mean if i want a fast quad i got my 87 250r thats all lonestar with a ct330 and i know for sures that quad will rock any quad and im not to firmilar with 400ex but yea the 440 has beter suspention and a little more up grades but i know the curtis has an overhauled engine but the suspention in rear was never touched.and i added up the total on bout bikes and one had a lilltle more money into it but i just want to know which ones beter as overall and would you guys know how fast there quads run thanks for help.

 

i would go with the 440.
