Tuning the S&S can be easier with the pump shut down. It can easily cover a too lean mix. Use the roll on method as you rev up the low jet to main has a pretty defined switch. The air bleed controls that switch and can move it up or down the rpm.

 

What pipe are you running, Scott's advise is very good. If you get me a pipe model I can get more specific.

What Scott says should be close. I've got a 113 at 10.8 with the 640 cam advanced 3 deg. In a bored G. (1.860)

.031 pilot, 78 main, 160 air bleed, 160 Thunder, Thunder air bleed cross drilled to 0.062. about the same on accel.

Ignition is Dynatek 2KI , curve 4, T set at the far left of the hole (about 27 deg full adv.)

 

Of course you know you need a good dyno tune.

Find a remote road and run it up (3rd, 4th, or 5th) and bring a set of gloves and a plug wrench set up with you. SPIN IT TO 4-5 K AND PULL IN CLUTCH AND CUT POWER.
As said turn off (all the way in) accell pump to eliminate masked (false) readings.
Now, pull over, and pull plugs (front and back -important). Then take pictures of both. Obviously its rich, but when, where, and why is the question. If it is fine spinning up at 3 or 4 k plus, but when you slow into town and putt into your garage,its fat, then.... its a worthless picture and reading.
I run two G's on my daily driver so you should for sure be able to dial in one.
I like to tune (if I dont have a dyno handy) in stages.
1.
Starting, riding slow light to light, stopping-pull and check.
2.
leaving a light on an open road, going thru gears up to 50 or so-pull and check.
3.
Full on power, pulling hard under load and max to full freeway speeds-pull over and check.

As Scott said, it is only a guide...every motor is different, so if someone tells you what jets you need FOR YOUR SPECIFIC APPLICATION..well....
I manipulate my jets to allow everything good everywhere, but it ain't EZ.

 

It has the bassani 2 into 1

 

I had a set on my Evo and they really knocked down the hp and tq.....

 

How did you make out?
Scott

 

pulled the super G back off playing with needle position on the mik 45. pulled bassani and put my fat cat back on. plugs looks a nice tan color bike is running cool and strong. next step is dyno tune or like others have said get a afr meter.
