Jetting!!! Again and again and again!
stujordan:
Would either cause me to run rich?
Foxx4Beaver:
for you to be running as lean of settings as you currently are, and saying your plug is "brownish black"...hints towards a weak top-end.
it doesn't necessarily mean it's weak, but yeah, it would cause you to have rich running symptoms.
the usable range for compression in the book is 105-164psi...for a stock motor.
It wouldn't hurt to check it...then you can rule it out, or if it is weak, you can freshin it up, cause there'd really be no reason tryin to jet a weak top-end, you'd just be going backwards.
not to mention, the leaner you go, the more stress you're putting on the motor...which only accelerates the wear.
stujordan:
When I get home sunday ill post a pic of my spark plug....might be giving u the wrong color....
stujordan:
Just noticed my bike doesnt surge anymore....recently moved to an altitude of 320 feet from 1800.
Smokes a good deal at startup...but smoke goes away a little when motor heats up.
Also it idles just fine hot or cold...not like before.
Anyone else running a n82r needle? What clip position and altitude?
The mid and top feel flatter than before too....use to hit like a freight train....now it feels mild.
Just replaced the air filter with a UNI....soaked it with 10w40 and squeezed out the excess with my monkey fists....still too much oil?
Setup:
FMF Fatty
52 pilot 2.5 turns
150 main
N82R needle in 1st position
Uni air filter with maybe too much oil
Both vents open
32:1 non-ethanol 90 octane (clear gas)
Ideas?

thats a good jetting base...
why you dont use airfilter oil?? :? .. you need no much oil . turn the airfilter inside out, take carefully enough oil on , and squeeze it a little bit , up to the point that you feel the airfilter has an little bit oily surface. turn back put on the cage and install in the bike... after that it could be that your bike will run leaner, because of the more airflow now... :wink:
