This is a great site, I thought I was the only guy that prefers alum. I have a Suzuki V-twin 25 and was wondering if anyone has tried to get more go out of one of these? I was told that you could get more by changing stuff or rejetting, but they did not know for sure. This motor runs good and I got 28MPH on GPS, but still wouldn't mind if it had a little more go. Any help would be great.
