ok so my plugs looked great all day after the first hard ride on the new pistons and timing plate. the end of the day we rode a long rode back to the garage so we really opened them up i would go WOT for about 5-10 secs let off and go WOT again that was for about 3-5 mins of road. now i did have to go back up the road in WOT (buddys shee blew up behind me). when i got to garage i pulled plugs and they looked like they were getting copper/reddish? were they starting to lean? should it have done that? my mods adjustable timing plate +2, t5's, .60 over, hot rod crank, boost bottle( i know it was there when i bought it), cool head 21cc dome, 270 mains, boysen dual stage reeds. any help would be good thank again HQ.
