I recently had my quad modified. It's now a 686 with 12.5:1 compression, webcam stage 2 cam, proflow filter, lte dual exhaust, stock ignition and jetting was done using a dyno...it was only making 36 horsepower and I had the mechanic look into the problem bc he said it was my exhaust which I thought was bs. My dad is keeping an eye on it and I forget what he said but it had something to do with the valves and compression...can the valves be choking my raptor up this much? Thanks in advance for the help!
