I thought I researched motor builders and had picked a good one. I was WRONG!!! Hot shot motorworks BEWARE!!! Do not use them! I had them build my 88 inch to a 95 inch. All kinds of problems. First they told me 2 weeks to complete, it was over 2 months before I got it back. Then it had a horrible tapping noise which ended up being piston slap from improper machine work, and I had an exhaust valve sticking and they installed my oil pump out of align. Ended up costing me two times more than it should have and he would not help me out at all. Owner was a jerk about it, blaming other people. Horrible horrible experience. Do yourself a favor and look elsewhere!
