I remember the graph at the bottom of the dyno sheet...there was the pre-pipe/air cleaner line (I think a blue line) and then there was a post pipe/AC line (I believe it was red) both lines were very close to each other and smooth with no jagged spikes. They told me this was good ? I will get a copy of the dyno sheet from the dealer/scan it and post it..then you can see what is going on....I trust you more than I trust them so your input is GREATLY welcome... would the bike stumble or misfire running lean ? I know it will cause the bike to run hotter (not good) I have about 45 miles on the bike, the pipes and the dyno was done with only 7 miles on the bike..(I know only 40 miles in 1 month !!! but its winter here in Illinois !!)

 

Probably but not necesarily, depending on how lean it was.

 

I wish I would have found this forum before i did the pipes/ AC, at least then I would have known what to ask the dealer !! I trusted them to do it right and now it sounds like they may have cut me short !
