KX500 AF Running like a 200

Does the bored carb change the jet size i would need compared to that chart?  I ran the bike side by side today wit a cr5.  The cr5 deff got more balls.  The CR just seemed to have way more snap and could pull the front end with ease compared to the KX5.  Seems like i got quite a bit of gass drippin out the bowl overflow.  If im in a higher gear and lug it she doesnt seem to have near the torque the CR does in picking up power.

motopunk:
the jetting guide is a good base ... fine jetting only with looking the color of the sparkplug and short testrides . never on an cold engine...

RKPerformance:
Just checked the plug and she is black.  Quite a bit of carbon crap built up around the bottom of the plug (not the electrode part)  Running a br8eix iridium plug.  Think it is safe to try a 162?  That was what was i there with the 250 pipe on it and it ran the best with that jet.  Obviously things have changed now, but it sure seems like the plug is black and crappy looking.  Carb says PWK V820GG07

Motorrad:
Always set float hight before jetting...

Do that.  The correct external way...


Then go look at the jetting I recommended on page 4 of this thread
