Having had my '08 V2 since new and recently replaced the second stator I'm considering selling the twin. I have ridden the V4. Hell of a bike, much different than the twin. Not necessarily better, just different. It's faster, quicker handling, less comfortable and gets relatively meager gas mileage. I have looked at threads comparing the two. Seems to be no consensus as to which bike is better. But general agreement on the differences. My questions to forum members is are there any know issues with the V4, other than it does run hotter than the twin? If I decide on the V4 it would drive me crazy to,come up,with the electrical problems I've had with the V2.
