Haven't riden my duc (1999 M900S) since being out of town for the past month. When to start it the other day just to get the juices flowin' a bit and it started right up. Today, went to go for a ride, and she just wouldn't fire up ! I checked the usual suspects: got spark, got fuel, etc. but no go. A couple of times crankin' her over, she actually backfired - scared the sh*t out of the neighbors! It's probably something stupid I'm overlooking but I don't have a lot of mechanical experience with these Italian ponies. Any thoughts or suggestions? Much appreciated!
