No Guru here but I really like the fuel injection. I've only ridden 2 I've worked on but they are smoooooooth. I Have 2 more I'm working on at present. I believe the most over looked item is the replacement of the filters in the fuel tank and injector maintenance. Out of site, out of mind. I love the way they start up after sitting a while. Boom running. They do need a battery switch. I wouldn't hesitate but the other stuff can bite you as well. Be careful with your purchase lots of junk out there.
