    * 1980 ATC 110/180 "Danny's Machine Works" 3D Sprint Dune Bike

    Hey guys want to share with you some History on this bike. I've had several people ask about it. It all started with me trying to run down 90-110 Old School HiPo parts. Back in the early days my brother and I used Danny Duncan of Danny's Machine Works in Santee California to build our race bikes. Danny was very well known in Southern California as one of the premier hi-performance motorcycle and ATC Speed Shops. He specialized in 4-strokes doing many hi-performance articles for 3-Wheeling Magazine. They built most of the team BAPP Bikes and Davis Mueller was their team rider and was featured in their ad.

    Fast forward to today and going back to my search for 90-110 HiPo parts I called up Loren Duncan. Danny's son. He helped Danny for several years and eventually took over operations and now runs one of the largest Hi-Performance ATV shops in the World with numerous Championships to his credit. Duncan Racing International.
    In talking to Loren I mention to him that I had some pictures of his old custom Dune Bike they built in 1980. My family took a trip out west in the early 80's and one of the stops on the trip was Danny's Machine Works.

    Loren said he still had the bike! To make a long story short (lol) we ended up making a deal and the bike ended up in Tennessee. It had been setting for many years. Loren said he figured the last time it ran was around 1985.

    This is how the bike looked with I got it.......

    It was in pretty rough shape to say the least. I was undecided on what to do with it. I first wanted to restore it back to like new but got to thinking it is only original once and decided to leave it like it was and clean it up the best I could and preserve what was there.

    Here is the bike today:

    Funny, I was just pursuing Duncan Racing's website. It's strange seeing the state of the art from yesteryear when you have today as a reference point.

    Didn't get the trophy's.......or the story board. That would have been really cool. I just figured it was long gone. I may have to ask Loren if it is laying in a corner some where.

    I was really fortunate to get this bike and I really appreciate Loren and his Dad Danny entrusting me with it. It will remain in my collection from now on.
    The thing runs great and is a blast to ride. Really forgot how awesome the 180's are. I will post a vid of me getting it running for the first time soon.
    Thanks for all the great comments. Just wanted to share this piece of ATC History.

    Like I said earlier the bike had been sitting since the mid 80's so I had no idea if it would run or what shape the motor was in. I cleaned the carb, changed the oil and plug. Checked the valves, points and timing, shot a little oil in the cylinder.... got gas to the carb choked it and pulled it three times and it fired up. It was like watching an episode of 'What's In The Barn" lol. I couldn't believe it. It was tight, didn't rattle or smoke. You would have thought it was ran at least twice a week.

    Here is a Vid of it running for the first time in 30 years!!!
