Mike,
Yes, Yes, Yes and Yes, but NOT at the same time. Everything you said is correct. If you want more power, buy the aftermarket air filter and see what that does. Also play around with your jetting on both the main jets and the idle jets. This was sent to me by another fellow on another forum:
You need to test the carb 3 different ways,
low range(idle)
mid range (4-6000 rpm)
high range (8-9000 rpm)
High range
In this range the needle is doing nothing, it is wide open the jet is feeding the fuel.
Clean the plug and re-install then run the bike in 2-3'rd gear with the rpm's in the 8-9000 range, steady for 30 seconds.
Hit the kill switch and push in the clutch, let the bike roll to a stop and remove the plug.
If it is white it is running lean and you need a bigger jet(probably not).
If it is milky brown you are right on the money.
If it is black you are running too rich, go to a smaller jet.
Mid range. The jet and needle are working together to supply fuel.
Clean the plug and re-install then run the bike in 2-3'rd gear with the rpm's in the 4-6000 range, steady for 30 seconds.
hit the kill switch and push in the clutch, let the bike roll to a stop and remove the plug.
If it is white it is running lean and you need to raise the needle.
If it is milky brown you are right on the money.
If it is black you are running too rich, you need to lower the needle.
Low range, the bike is getting its fuel thru the pilot jet.
Run the bike in neutral with the rpm's at idle for 30-60 seconds.
hit the kill switch .
If it is white it is running lean and you need to open up the pilot jet.
If it is milky brown you are right on the money.
If it is black you are running too rich, you need to close the pilot jet.
