Why no kx250 jetting database?

Recommended Posts

Why do we not have a jetting database like the Ktm guys ?

Or is there one ?

Is this something I should start?

Where in the powerband do you ride (Lugger - for technical stuff, or wide open - desert / MX): 
Degree of satisfaction:

Might want to add displacement onto the list. My 265cc kx runs alot smaller jets than a stock bore.

 

just out of curiousity is it smaller just on the pilot jet and starting taper of needle ?

is that main not to lean with a fatty pipe ?

No not at all. Larger displacement means it's going to pull more vacuum in turn pull more fuel. The bigger the bore the smaller your jetting gets. (Most People figure it'd be the opposite )

I've tried upping the main jet one size and I can get away with it in really cold weather but in normal riding weather it fouls a plug every ride.
