yeah, i am interested in seeing that one.

 

not having an accelerator pump does'nt mean that it'll loose low end , they've just found an alternative to the fuel delivery in the lower range . possibly a larger slow jet , or just a differently machined carb . after all if they were all the same it would'nt matter . i do think that an accelerator pump helps for starts , gets you out of the hole faster and out of corners aswell . mainly because of the instant shot of fuel rather than waiting on the slow jet . not to get to far off topic , but has anyone ran or know someone who has ran or is running a dial-a-jet system?

 

Found it Jan 2002 ATV Action the carbs are Keihin 41 and 39 mm FCR, Lectron 38mm and Edelbock 38mm tested on CT 440 big bore kit.
