You can run it in untill you feel it bottom out with out hurting it the way your doing it, then back it out 2 1/2 turns.

 

You may have to remove it and see if there is some dirt particle or something keeping it from turning freely. You don't want to turn it in too hard or you could do some damage.
After adjusting them, you should use a small dab of silicone to keep them in there. Some have trouble from them vibrating out and losing them.

 

Yeah, I'd take the screw out entirely. There will be the screw, a spring, a small washer and an o-ring in there. The blast any crud out with a few shots from a can of carb cleaner (don't get any on your paint!)

Use some carb cleaner to clean the screw, spring and washer. Try not to get any on the o-ring. It shouldn't hurt it, but best to be safe.

After that, put it all back together.

The order it all goes back into the hole is:

o-ring
washer
spring
screw

Then set it back 2.5 turns from a light seat to set it close to Honda spec, or set it out 3.25 turns if you have some deceleration popping.

Is this 2 1/2 turns for all shadows? I have a Spirit vt1100c1 and I'm wondering if thats the setting on mine as well. i borrowed a book from a friend and it says 2 1/2 turns but its for the Aero vt1100c3 and to also adjust the throttle stop. I put new pipes on and its popping.
