Anyone is or know of local engine builders? Its for my TLR, so should cost half as much right? Its only two cylinders!

I haven't touched the bike in a bit, and I know when I parked it I had a water leak. Based on the work thats needed, time and that I have never done an engine before, I am considering options to get back on 2 wheels. Love the bike so its worth the money, I don't see selling it so thinking I might give the old girl a full on rebuild. Also considering options on putting a couple extra ponies into it, but all that would be price based.

Do we have any local motor gurus or engine shops? COS / Denver / area?
