I'm having a really hard time trying to adjust my mixture screw on the bike. I end up having to take the carb out or turn it on its side. I was wondering if you guys have a trick to adjusting the screw? or If you have an upgraded screw like this,
While "trick" idle mixture screws exist, such as the Koubalink T-Handle (you'll need model FS-2 for your KLR):
I think the idle mixture screw is accessible with the carb mounted on the engine with a little, tiny, flat-blade screwdriver, or, with an offset screwdriver.
In my experience, the idle mixture screw, once adjusted, remains more-or-less, "set it and forget it." Thus, I'm willing to wrestle with the tight quarters and awkward access of the OEM configuration, for what to me has been a seldom-adjusted component. YMMV!
Men say the mixture is dominated by the needle and main jet beyond 1/4 throttle; then, some say the idle mixture screw's setting remains critical up to (and beyond?) WOT (wide-open throttle). You decide!
