OS 91 Surpass valve keeper?
I just disassembled my 1999-2000 version of the OS 91 Surpass engine that has performed flawlessly!!! i flew it until 2003 and then parked it for family issues. Upon disassemble, i found it has been operating with ONE keeper on the intake valve. I would pay for one keeper and handling if someone has one extra???
i'm not sure what OS has in the way of packages, i just need one.......
