My GS is having some starting problems (or so it may seem). The bike won't start when the clutch is fully engaged. I have to rev the throttle a bit to keep it idling. I thought it might be something with almost being low on gas but even with a full tank it's the same thing. Any ideas? Thanks.

what is your idle set at?  it may be set too low.  manual says to set the idle to 1200 rpms

I was messing with the idle earlier, but I'm not sure if it's quite at 1200rpms. I'll mess with it again tomorrow and post the result.
