This guy sold my customer cracked heads. Upon finding the cracks, I told my customer to return the heads. Pat at Kinetic would not exchange the heads. I have heard all kinds of stories of Pat's incompetence over the years. One old time 1%er stated that a motor Pat built was so "tight" that when they fired it up for the first time they had to run water from a garden hose over the motor to keep it cool enough for it to run... Another former customer purchased a bike from Pat that had major electrical issues that Pat had wired.... This guy appears to be a basement builder. Your mileage may vary... You have been warned.
