Here are the pics of my plugs can someone tell me if anything seems out of the ordinary or just interpret the plugs. They are Rear trailing, Rear leading, Front trailing and Front leading respectfully.









Thanks

Way rich. leading plugs sould be tan in color.

 

the same Tan that is on part of the trailings? Also I premix so do this change anything?

 

Some oils don't burn as clean as others and will leave deposits on the plugs. You might try switching brands of 2 stroke oil. I premix and my plugs come out toast brown to light brown. the trailing plug will tend to be a little darker. Are you mixing 100:1?

 

Yes I mix 100:1...I probably just need to do some tuning on the PFC to lean out some. Do u think this condition is mainly from Idle or from cruising/driving?

 

No way for anyone to know without alot more information about your setup. Are you using a wideband? Inj. tuning is not for the faint of heart, there's some good information in the PFC section as well as some good tuning guides available.

 

ok...Well I'll just have to live with being rich for now until I can get some good tuning done.

Thanks

The corrosion.... have you had the same plugs in long?

 

I pulled these out yesterday and and put new ones in; i believe these plugs have been in there since the motor was rebuilt (27k ago).

 

I only got about 7k on my last plugs. Mid 11 AFR's. They look nasty after a long time in the motor. That's me anyway.
