I have a spare o2 sensor and a multimeter sitting around could i just shove it in the exhaust pipe and tune it that way?
I'm new to bikes after some 35 year hiatus but from my autocentric mechanicals POV, no.
Unless you understand how the sensor you plan to use works.
I doubt you could get any meaningful information from the older 'unheated' sensors.
could anyone give me a sure fire way to adjust the air screws?
You're adjusting idle mix, right?
You have a twin, right?
Back in the day we would....
Pull one spark plug. Get her idling on the other cylinder and adjust it's mix for fastest idle then make it just a hair richer. Do the same for the other jug.
On fours, I have found the only method that satisfies is as follows.
1)Sync carbs using a round guage pin that opens butterfly about 1/4 to 1/3 of the way. Set linkage screws until they all have the same clearance.
2)set the idle screws at factory recommended or forum recommended number of turns. Turn 'em all in and out at the same time in 1/4 turn increments until idle speed peaks and then adjust 1/4 turn in rich direction.
3)check vacuums. If they are not even, then I have another problem to solve.
4)let her idle a while and check plugs to see if even and not too rich. If plugs are not even, I have another problem to solve.
I know this diviates somewhat from forum recommended practice, but it's been working for me.
