I have the mags off and will be at the cases soon I will put a set of everything through the rotaxs as they have been in a carboard barrel for 25 years, it is amazing they started and ran beutifully for a while then when down slowly over a few hours, the carb on one was leaking but I fixed that and they ran good then the rev counter went silly and I fixed that, then the motor started to hunt and I fixed that. then they were left for 12 weeks and first time out began bubbling at the crankcase in the same spot on both motors, so that means they are sucking air and need new gaskets. I will feel a whole lot better knowing they are overhauled and running well as it wouldn't be nice to find out at 5000 ft and 20 miles from home !
