I had a head repaired at Engine Dynamics and an hour into the first ride the same problem (cam seizing) re-occurred. Tore the motor back down and sent the head back to have it redone. The gal in their office calls when it's done and we discussed shipping methods and costs and settled on two-day for $50. All this time I am assuming that the re-work on the exhaust cam lobes is a warranty item. When my card bill arrived and I saw the $238 bill I called and all I got was excuses on why they had to do more than last time and why it is all our fault that it failed. Mike made it clear that he never works for free! The way we left it is that he is keeping all of my money unless he has a change of heart at which point he will call back:banghead: I'm not holding my breath on that one! Who else does this type of head repair? I have heard that someone on the east coast does these also.
