    And... first ride completed. I learned a couple things.

    1) it's only got two gears. I think I must have indexed the selector box 180 degrees off, not a big deal to fix but I'm letting it cool off and won't know for sure until I pull it off. I did the same thing when I put my 750 together, you'd think I'd learn!

    2) When disconnecting the rear brake cable near the end of a project, it is best to reconnect it before the first ride is taken. No harm done. Front brake works.

    I'm sure I'll find other issues as I start to put some miles on it in prep for Barber, but I doubt I'll be doing much updating between now and then. There's really not much to say anymore. So, here are a few pics from it's first outing.

    Edit: Thought I'd toss a "before" pic in here too, just for yucks.

    Oh, one more thing. It started first kick each time I fired it up today. I'm loving that!

    Thanks guys. Yeah, I'm pretty happy with how it turned out. There is still work to do though, a lot of detail stuff isn't done and won't be in time for the meet.

    That second to last picture is the angle I see the bike from in my workshop when I'm sitting at the bench. I caught myself sitting there and gazing at it today a few times. And this wasn't the first time for that. But when I'm gazing at it I also see a lot of mistakes and think about how I can fix them... :hmmmmm

    Mission accomplished. After three hours of sleep plus thirteen hours of driving, the 160 is at barber!

    I can't believe i missed your previous updates!
    Congrats on finishing this little beauty!
    Have fun at Barber.
    Seems like you should occasionally post up a new picture of it in once of the great settings you take it to!

    Thanks guys. I'm posting this from an iPod, didn't bring a computer this trip! Point being I likely will not have any updates and certainly no photos until I get home.

    It's in the hotel lot right now. I plan on riding it over to the track today and putting it in the Ducstock area.

    Well, I just got back to Michigan a few hours ago. About 13 hours each way... it was worth it though. I'm pretty wiped out right now so this probably won't make much sense. I just wanted to add an update on how the weekend went and how the 160 ran.

    It was my first time at Barber, the place is amazing. Spent much of one day in the museum and was overwhelmed by it all. While on the 4th floor taking a breather I heard something and discovered an air show going on just outside the window. Window as in floor to ceiling the entire length of the building.

    The next day I was volunteering at the Ducstock event and the airshow took place right above my head. I've never had a plane diving straight at me before. It was pretty cool, just like in the movies. Except there were no guns blaring, which was fine by me.

    Amazing event in general. Wonderful venue. The Ducstock part of it was pretty impressive two, I'm sure there were over a million bucks worth of bikes in the tents not to mention all the spectator bikes at the show. The 160 didn't win anything but I didn't expect it to - not stock so it wasn't a restoration and not custom looking enough to appeal to that crowd. I did get a lot of positive comments on it though and not once did anyone tell me they used to have one just like it, so all in all I'd say it went over pretty well.

    It had about 15 miles on it when I loaded it in the trailer to head down there. The shifter issue turned out to be something else but was still an easy fix. When I put it on the trailer I knew of a couple issues but they were nothing that would keep it from making the trip.

    The first morning there we fired up the bikes and headed out into real world traffic, promptly getting lost. Within ten minutes I was climbing a steep hill which I then had to come back down. The guy following me knew my brakes weren't great and was a bit worried I wasn't going to stop. It didn't help that I had forgotten to flip on the battery power for the brake light... but no need to worry, everything was working fine (and I remembered to flip the switch a few minutes later). Long story short it got thrown into the deep end the first day out and I must say it handled itself much better than I expected.

    I was planning on riding it to the track that first day and probably just leaving it there the entire weekend. But, the road from the hotel to the track (once we found it) was perfect for that bike and I rode it to and from the track each day, grinning pretty much the whole way. I think the bike probably ended up with well over 100 miles on it (no speedo/odo yet) and a significant portion of that was at WFO. Break in period? We don't need no stinkin' break in period! (Actually I think it was a great way to break it in but that's a subject for a different post.) FWIW our group consisted of me on my 160, one buddy on a 796 Hypermotard, and another buddy on a Streetfighter. Yes, I was chasing a bike with ten times the HP of my bike each morning and afternoon. No, I did not keep him in sight! But I did better than you might think.

    Using the Hypermotard's speedo as a reference it looks like the bike will hit maybe 65mph on level ground with me sitting up, add a few more mph with me tucked in. We didn't get a firm number due to the lack of a long level straight but these numbers are higher than I expected so I'm happy. I haven't checked the magazines to see what the reported top speed was for a stock Monza Jr. Maybe I should before I get too happy about this!

    I can also report that there are three big twin Harleys and one large-ish 70's era looking bike of unknown, possibly British, make out there that have been reeled in, passed, and run away from by a 160cc Ducati. And let me tell you, it wasn't due to my superior acceleration.

    Long story short before I fall asleep at the keyboard, the bike did itself proud. The main issue so far is a bunch of false neutrals, I have to spend more time adjusting the selector box. When taking it easy it shifts fine, but when trying to hurry things up, like when a light turns green and an SUV is coming up fast, it would miss gears and generally act up. There are numerous other things too.

    Some good stuff - The seat is more comfy than I imagined it would be. I'm surprised at how easily the bike rolls around. And the engine is running like a champ. This will likely jinx it but I can't believe how well it runs with what are essentially my first stabs at carb settings and timing.

    And that's it for now, time for bed...

    Hello Craig,

    I have to tell you I saw your bike at DucStock and I fell in love with it.
    It is the perfect little single and I want to congratulate you on a job really well done.

    I was looking through this post and it's amazing that you were able to turn what you had into what you have now.
    I have to tell you I took about 30 pictures of the bike but I want to send you one or two of the best ones.
    If you could hit me with an e mail address I will forward them along to you.

    Again thanks for bringing that bike out and providing me with some much needed inspiration to do my own single.

    Thanks Jimi.

    I sent you a PM, I'd like to see your pics. I've been meaning to post a pic of it at Barber but I only took a few and none of them are very good.

    I've got a list of the things I still need to address on this bike, but I have to admit my thoughts now seem to be centered on getting my 350 up and running.

    In the show on Saturday - Ducstock 2011. Made it!
    [​IMG]

    The 350 Sebring next to it gives a little sense of scale, this is a small bike.

    Here's another shot that might give a better idea. That's a 796 Hypermotard behind it.

    DesmoDog, I absolutely LOVE your bike. You did a great job on it. I really appreciate that you documented the build so well and posted on this site so often. I'm sure that this build has inspired quite a few people. Thanks and enjoy that little Duc!

    Congratulations Desmodog, on doing such a fine job! I really like the lines of the bike and how the tank and fenders work in harmony to bring together the whole bike. It must be very satisfying to ride it!

    Thanks guys, the bike has been fun so far. I've had it out a couple times this year, it scoots along pretty well. One of these days I need to get a speedometer on it.

    The only other bike I've been riding is my Hypermotard. The first time I came to a stop on the 160 I surprised myself when I put my feet down, dang that seat is low.

    You know I was meaning to do that but it seems I haven't. It's been to a couple of events since Ducstock, never entered into anything though. Today I took it to work to be in a car show/BBQ/picnic event they do every year and thought it might be a good time for an update.

    The bike only gets ridden a few times a year. I never did get around to fixing all the little details I left undone before Barber, I pretty much just ride it now and then.

    When rewiring it, I added a front brake light switch and a kill switch. When I re-adjusted the front brake on it about a month ago I discovered the brake light was always on. Disconnecting the front switch solved that. And the last time I rode it the kill switch self-destructed. So now it's back to stock form I guess!

    So like I Said today I rode it in to work, about 25-30 miles each way. Since I still don't have a speedometer for it, I put a RAM mount on what is supposed to be the tach mount, and use an speedometer app on my iphone to gauge my speed. Either htis thing isn't running as well as it used to or my initial speed estimates were off. Sitting upright on it, it'll cruise along around 55mph on more or less level ground. Tucked in it might hit 65. Maybe.

    This morning on the way in I realized that the road I take is uphill a lot of the way in. Never noticed it before. In some areas I was struggling to keep a steady 50mph, but the speed limit was usually 45 so I was good.

    I took a different route on the way home and had a little higher speed. Maybe it was just running better in warmer weather but I'm thinking it's mostly downhill on the way home. It would make sense I suppose. If I remember I'm going to check with an altimeter app.

    Whatever. I made it in with no drama. Turns out I was the lone Italian in a sea of Harleys. (The cars in the background are simply parked, not part of the show)
    [​IMG]

    There were some nice cars there, i didn't get pics of them though. My boss told me he was voting for my bike and I told him it was a wasted vote. People don't like small bikes, people don't like black bikes, and we are in the car business after all.

    Turns out the joke was on me. The mighty Duc ended up in a 3 way tie for second place when the votes were tallied. They then drew among those three for places and I ended up as 4th but so be it. First place was a very nice 1968(?) Mustang. For comparison, when I put my 750 in this show a few years earlier it wasn't even a blip on the radar.

    After the show I rode over to the shipping scale and put the bike on it. Any guesses? I figure it had 2 -3 gallons of gas in it. I was guessing it'd weigh in around 270 lbs...


    And the answer is:

    [​IMG]

    247 pounds.

    So there ya go. My annual 160 Monza Jr update.

    Are those aftermarket Lucas electric components?:lol3

    Although it was ages ago (and I weighed about 150lbs then), I could get an indicated (with the wavy Veglia) 85+ out of the 160 and it never struggled on any hill.

    My recollection might be colored by the healing mists of time in my mind, but I think your Jr should be doing better.

    Yours sure looks WAY better than mine ever did, though!
