The bike should run okay, as long as the PMS
is out far enough. You could even run the bike with it out as far as 3 1/2 turns. You may want to try it.
Once you get it so its running fine, then you can start the tweaking.
I turned mine in from about 3 1/4 turns to start, to the 1 3/4 or 1 7/8 turns out where it is now, over a period of several months(I didn't have the E-Z Tach right off). It ran fine even at the 3 1/4 turns out. I'd ride it for a few weeks, and then one day after coming home from running errands on the scooter, I'd adjust the idle up, and turn the PMS in a bit more, and then set the idle back down and try it for awhile. Some people haven't been able to get their bikes to run right around 2 turns. Some have theirs set out beyond 3 turns.
To properly warm the bike up, you should ride it aggressively for 10 or 15 miles at least.
Then adjust the idle. After the idle is where it needs to be, you can very slowly turn the PMS in to where you hear the idle start to stumble. Don't turn it in to quickly, and pause to listen to make sure that when you do hear the stumble, its a real lean stumble, and not just the normal slightly irregular heartbeat of a Roadie.
When you do hear the stumble, back the PMS out about 1/4 turn, button it up and try it.
