routing of throttle cable

I had my 305CSR out yesterday, working bugs out of it. Right now it is unusually warm here in PA. Getting outside!!

The idle would vary: sometimes right at 1000 and others it would not go below 3000. I also noticed that when I turned the handle bars to the right that the engine would rev up to about 5 grand. Today I pulled the tank off and it looks like it might be better if the cable routed on the left side of the frame (it is on the right now). I could not see the throttle move when I turned the bars to the right but if I pulled down on the cable in the middle that the throttles would move.

Any other suggestions?

Thanks,
