From what I gather from these folks, 2.5 to 3 turns max. If you need more than 3 it is time to rejet. When you turn it, you will need to wait 15-20 seconds to see if there is a difference.

Also, at 2.5 turns out and more we have had some reports of the screw simply falling out due to road vibration as the spring won't retain it properly when turned out that far.   So this is another good reason to go ahead and rejet if you have to turn it out that far.

Bad terminology.  He should mean 2 to 3 turns out (from all the way in).  At 3 turns out on a worn screw, you will shortly need a new screw.

The dent puller is a must for easy removal.  I used one today and it worked well.

I need some help! Here'a a quick update.

I live in San Diego at Sea Level, inland about 15 miles but get some humidity from the coast. I bought the bike a little over a year ago with 4500 miles.  It was a good deal and needed little maintenance so I got new tires, front breaks, changed my petcock to a raptor, my muffler to a DYNA, switched to Rotella Synthetic for my own peace of mind and raised the idle just a bit.

Bike ran fine but I've had some backfire that I could only control a bit with the clutch so I decided to remove the brass plug to adjust the jet plug today.

I screwed the plug clockwise all the way in and ended up going back counter-clockwise approximately a little over 1 and a 1/4 turn and turning the idle down less than a 1/4 turn from it's current idle adjustment.  The bike runs fine but I'm still getting some backfire.  I checked the exhaust pipe with a lighter and I don't seem to have any leaks.

What may anyone suggest should be my next step? Do I keep going counter-clockwise on the jet screw and then adjust the idle as needed?

Thanks for all the help, I love working on this bike.  It's so inexpensive.  I plan to slowly modify the body once I get it running optimal!

Don't have a dent puller?
After drilling the plug, knock the point off a drywall screw & run it in 1/8".  Grip it with Visegrips & tie something with a couple pounds of weight to it, leaving a foot or so of slack in the line.  Snatch it like you would a dent puller.  Just keep a hand on the Visegrips so they don't drop on the engine.

Ever thought about going to Dental School?
