2003 savage and i have put a harley slip on # 64941-01 and a new lancer carb kit on this bike to fix where the mixture screw was eat up.. replaced that also...

and then i adjusted screw 2 1/2 turns out.. bike sounds nice .. runs great except on speeds of 60+ she dont seeem to be getting her full clean run? just to me..
i had cleaned the pipe coming out of head with blue job stuff and had it real nice and shiny and now all of a sudden i notice the pipe is going back blue/purple..
I was told that this means it is running lean...?
surely not though..?
it actually seems to me to be running a little rich not lean and at 2 1/2 turns also? i dont wanna turn it out any more than it is now?... rather rich than lean.. i dont know if its running rich of course but intuition..?
whole point is it possible i have a issue?
the reason i did all this was to make the bike better from Past Owners mistakes...
even though i ride everyday.. i live to ride with short sleeves

and its getting bout that time
thanks for any info ...
Peace
