Please help! When adjusting the valves on my 8500 mile el250, I found one of the intake rocker arms had slipped sideways off the valve. The cam has a nick out of the center of the lobe. I replaced the cam cover without further disassembly until I can be sure parts are available. The cams are still listed on Bike Bandit, but no valves, springs, etc. Does anyone know how this happened? The bike ran fine, with just a little valve clatter. I don´t see how that´s possible. Is there anywhere I can get replacement valves and related parts? Thanks.
