I just wanted to check with some other Spyder owners to see if you have the same problem; It does not matter if the engine is cold or hot - but seems right after starting the bike and trying to take off, if you let the clutch out to quickly or attempt to accelerate quickly the engine coughs and even quit on me a few times. I have two friends (one is a dealer) who have the problem as well. The dealer said he had others complain about it as well. Seems like after a minute or so everything is fine again.
