I'm gonna say, after a year with this bike, I have nothing but love for it. It has really impressed me, and my riding buddies. Having said that, I'm not happy about the heat on my left leg. I have had enough of it. My wife hates riding it because of it. I have heard of people swapping out exhaust, and,or, using a tuner. Of course there is vforce John flashing ecu. But that could take a long time to get back. Would you upgrade exhaust, or go with a tuner, or both? If so what are some great brands to look at. Thanks.
