Theres a knurled headed screw near the choke. Screw in to raise RPM. Make sure its high enough, at all times, to keep good oil flow to the head.
I have to raise mine a bit when I ride away, then lower it once its warmed up all the way. Not a lot, but to keep a steady idle, yea.

The book says 1000 to 1200 rpm.

$30~$35.  Two wires, one wrapped around the spark plug wire, the other to ground.

Go online to Onida Suzuki and look at Drag Specialties #DS244133. This is the black face tach and their prices are the best around. I've had mine on over a year now.

I just use mine diagnostically.  I leave the wire in place and hook up the tach only when I think I need to adjust the idle.

I suppose you could mount it somewhere permanently, but the update rate on the tach is pretty slow for operational usage, IMO.

Sort of.

I did not have to take the tank all the way off.  I just propped up the front of it enough to get access to the spark plug wire.
