I have had the same problem I have read about from others. The bike stalls at idle. When the Spyder was purchased there was a check engine light on. Then the battery died. The following items have been done.

New Battery
Drained and filled gas tank
Ran Seafoam through it
Replaced fuel filter
Drained and filled Oil
Changed Oil filter and HCM/Transmission filter
Replaced vacuum hoses with silicone hoses
Changed air filter

As long as the throttle is applied at all, the Sypder will run. As soon as the throttle is fully released it stalls. Haven't tried replacing spark plugs and wires yet.
