I made a dual snorkle for the prarie because i wasnt getting enough air with the headwork and cams. While jetting and doing plug reads I saw my plugs are red on the nose and has a red tint on the electrode. Also I had the temp light come on for the first time ever. Im already up to 155f/158r jets. It is runing strong but its not right. The high temps would tell me its lean but with the large mains and the red plugs Im not sure what to do next. Im running 93 octane pump fuel, didnt do anything to quad recently except add the dual snorkle, coolant level is good, fan runs, radiators clean, valves adjusted last week, one week old ngk plugs. What do you think??

 

Go larger mains and see if it darkens up. Too Lean, plugs should be whitish. What color is the base ring on plug? Don't recon the fuel has dye?[img]i/expressions/face-icon-small-confused.gif[/img]

 

The base ring is black. I was planning on seeing white on the nose but the red threw me for a loop.

 

I've seen this a few time and in my case it was fuel package additives. I've seen a shade of green also.
