Xr400-600 Carb??

Recommended Posts

Will a stock 1991 XR600 carb fit an 96 XR400.... and if it would increase performance.... might be a real stupid question, but hey I gotta know. Thanks guys.

i would not use a bigger carb unless you had a specific reason to.

here's a couple of reasons why

A bigger dia carb will allow the engine to rev out more

Starting could become more of an issue,

the loss of bottom end

less responsive between transitions say from idle to mid, not hesitation but rather a lag in tresponse, it is much more apparent under load , the motor would be more responsive say on a flat track rather that someting which required more modulation of the throttle.

All in all not a good plan.

Now if you wanted more torque a smaller dia carb would give you just that.
