I installed my new dobek on my roadking and got about 20 miles into the ride and got a head gasket leak. Does anyone think that its possible that the tunner could have caused a incorrect mixture in the cyclinder and caused this leak to occur. My bike only has 4,000 miles on it and I had no problems until after the install. Im being told head gasket problems are not that commen on newer bikes, so its just brings to question the tunner. It seemed to be very rich, as I came to stops I could smell it. I also had to reverse the polarity on my injectors so the tunner would work, and the guy at dobek ashured me that this was commen on my model. So has anyone eles had this happen or heard of it happening to some one?
