A simple jetting test copied from the Nightrider HD site.... do use 5th
gear at 4000 or better rpm. Warning see the NOTE !!
"Adjusting the main jetting requires a long stretch of open road with no
traffic. You must be in fourth or fifth gear and running at
3500-4000-4500 RPM. then open the throttle all the way to the stop,
noting the feel of the bike. Immediately let off about 1/8 turn and note
the feel of the bike. If the engine just slows a little, the jetting is
very close. If it seems to accelerate some when you let off the 1/8,
your main jet is too lean. If it hesitates or the top speed is poor
(i.e. less than 80 MPH) you are too rich. Adjust the main jetting
accordingly. Use your common sense and seat of the pants feel and you
will get close enough to do plug reads.
NOTE: (The Motorcycle Performance Guide staff recommends you take the
bike your local drag strip for this testing.
Your local sheriff usually has no sense of humor about a motorcycle
running down his roads in excess on 90 MPH).
If you are in doubt as to the jetting, make sure you jet on the rich
side (tan>brown>black). Because of potential engine damage, you are
better off slightly rich rather than lean. A lean engine can detonate,
causing permanent damage. <snip>"

I changed the needle and jets to what FLAASH suggested
and its defintely running better, but guess what...I'm
still not happy.
Now the problem is it does not have enough power in
high revs.
