When I first got mine, I seriously felt like I needed a tach. By the time ID found one, I didn't think I needed it. Ride it a while, get used to the sound and watch the speed.. You'll be changing gears without even thinking about it.

I ordered a tach from Drag Specialties two days ago My jet kit came today which I will be installing as soon as my new handlebars get here. Trying to do it all at once. I have no problem feeling and hearing the engine and knowing when to shift up or down. I really would like to know 1200 RPM when it is 1200 RPM so I have the idle speed correct and can adjust the air mixture screw more precisely. It would also help to know for sure if I'm in 4th or 5th gear. I've only owned the bike just over 3 months and have put 850 miles on it. It's my first bike. Did I mention that I'm 86 years old. Thanks for the help and comments.

Yeah. I understand you want to adjust the idle after a good 10 min ride at a low RPM ,bike vertical ,airscrew clockwise until a slight RPM drop then back out to a smooth idle. then increase RPM to 1100 to1200 RPM with the idle screw. Basic stuff.

When you choose a Pilot Jet.....I would start with a #50.  When you do the adjustment for the idle fuel mixture screw, you will learn if that is the correct size for your bike.  When adjusting the screw if you can turn the screw all the way in and the bike is still idling well - the jet is too big and you need a smaller pilot jet.  If you can turn the screw out more than 3 turns and the bike is not running rich - the jet is too small.

You want a pilot jet size that will have a smooth idle when the screw is out 1.5 - 2 turns from lightly seated.  (Once the screw is out more than 3 turns the hole is open and no more fuel will flow with additional turns open).
