are you still running a ton of oil in the fuel or did you drain that out?  too much oil can change jetting and cause excess bog as the oil doesnt burn as well, and it also technically lowers your octane level. 

swapped the tranny oil today, drained the rest of the tank, swapped plugs and warmed her up real quick. noticed a leak, I think its my right side carb, it looked wet around the bowl, so I'm gonna open it up check the gasket tomorrow hopefully fix that and take her our for a spin. I'll post the results & some pics of the plugs.

 

Did 32:1 Yamalube R... Currently 2 gallons in my tank

Took the quad out for a quick ride, rode 1-5 gears pretty hard. top gears ran great, noticed the sound the bike was making when accelerating was a bit strange (before powerband). Especially in the low gears, throttle response in those low gears isn't too great either, its hard to get the quad to move like I want it to in 1st, kinda like it has no power until the powerband kicks in.

 

Got back home shut it off and plug electrode is black and the rim & threading were wet with black oil. Wiped it off and put it back in.

 

Does this mean I am running rich?

 

E- Will post pics of plug once I can get it to my email

the best way to tell is to get the bike warm. put fresh plugs in to a 6th gear pull, and pull in the clutch and kill it.  then pull the plugs and do a chop.

 

looks rich to me. 

Those were fresh plugs, but yeah I'm thinking it's rich too, my buddy thinks so also. He tells me I should drop down to a 290 main. I'm at 310 rn. As for the strange sound I googled it and I ran into needle clip position, should I mess with that before rejetting?
