How often do you change jetting?

[Banditpowdercoat]

Just wondering how often you guys change jetting for temps and such?
I ride same few areas around my house. 1000' up to 7000' elevations. And from damp, 5*c days to 32*c I know I am fat jetted, she runs good, and I mostly am single track/ old overgrown horse logging roads in the BC Rocky Mountians. I haven't changed my jetting, and know previous owner never changed for seasons or temps. SHe is a 98 ec250 with PWK 38. My idle sure does change with elevation and engine temp tho. And the idle stop screw is all the way in. I have to take carb out and record the needles one day.
It's a 1998 EC250

But surely you guys are not taking carb out every day you ride to change?
