how do you know you lost hp ? did you dyno it befor you ported it ? did you use the same dyno both times? did the person know what they were doing that dyno'd it was it jetted right dynos varry you could make 90 hp one day and 76 the next just to let ya know its how dynos work
there are alot of things that can varry on the dyno..... a dyno isn't a tool to see how much hp you have because its practicly imposibal to get a acurate reading its more for like if you dyno with a certain pipe and change the pipes like right then and dyno
170 psi you should only be running a 50/50 mix
just wondering have you rode the bike at all to see how the power feals ? or just dyno'd it ?
just wondering all this stuff because dynoedge is pretty well known and i have never really heard anything bad till this
if your sure that they screwed your whole motor up i would get the fmfs just to show them that they fucked up....... but it also sounds liek there doing what ever they can by offering you new cylinders and no charge
