excess fuel coming out exhaust

[meangreen500]

I run redline 60 to1 mix with 100 oct fuel. Im running 48 pilot, 168 main stock needle. Im getting a lot of fuel oil spitting out the silencer. spark Plug is normal heat range. plug color is light tan looks like burning good. I cant figure out why it still is doing this. I was running 50 to1 and larger jets but I figured with going leaner and lowering the oil it would stop but no. The bike starts and runs great  plenty of power. I thought it may be it needs a mix of half 91oct and 100oct I figured you guys are good on here you might know. help

Proper Float level check... (external measurement, not just looking at float parralell) followed by....
Leakdown test im sure will reveal the anser your looking for as to why.......

2400 to 4000 las vegas area. float height is good forgot to mention it. I was thinking it might not be burning the fuel good been doing alot of slow riding course marking for our race.

When my head gasket blew it did the same thing.  Plug looked great, ran great, but it spit out the exhaust.  Swapped the head gasket and problem solved.  Something to look into I guess.
