    Right about now, those of us residing in locales that have 4 seasons are varying degrees of "can't wait to dust off the bikes & shake-off cabin fever". Here is a short vid to kick things off for 2009.

    For the time being, I'm making this thread a sticky. Where to take all things video from here will, I suppose, depend on how much interest/input is/is not forthcoming.:28:

    Ha! Nice job, racerx. Love the song, but not as much as the sound of that engine. Snow is all gone up here in Sudbury, so I imagine those fine Michigan backroads should be ready soon.

    I figured it probably wouldn't mean much to you, Harry. Folks in your corner of the world have been known to suffer hypothermia when the mercury drops down to 55F; around here that's shirt sleeve weather.:D This one was slapped together to elicit a few well-deserved grins after what has seemed one of the longest cold seasons in many years.

    The editing was done on a custom-built PC, running windows Crystal edition XP pro w/sp4 and a stripped-down version of Nero 4. I'm thinking of upgrading to Sony Vegas, but don't want to get too slick. These are just helmet cam videos, after all. They could get boring in short order. This was my first stab at video editing since the early `70s and I'm not too dissatisfied with the admittedly cheesy result. There's lot of raw material in the proverbial can and the intent is to post something new every couple weeks or so. These things are probably best when viewed during the winter. I'll keep them coming until they become stale or the humor element goes away. This is intended to be fun.:34:

    Nice vid! 45 degrees and pouring rain here in OH yesterday. The weather still hasn't turned the corner here, so my ride is still in the basement! However we did get in the 60's today, but it would have been in the 30's for the ride to work...I'm not man enough to ride when it's that cold.

    Keep the vids coming!

    I love it. I guess I'm spoiled here in FL for being able to ride nearly year-round.

    What part of the world is your residence Racer? Those roads remind me of my early years in WV. I love it there but wouldn't trade the sunshine for anything.

    BTW, I've used your information more than a dozen times in the restoration of my KO, HUGE THANKS! This video makes me want to take a trip with my camera down my clay grove roads right now, needless to say i'm restricted by the whole "Job" thing.

    Another thing, Interesting speedo, 12V or 6V system? And how did you rig it and where did you purchase it? (Eventhough its really cool, it still doesnt beat the analog original.)

    Another thing, not to fill up this strand with comments. The angle on your handlebars are different than mine. My bars are perfectly parallel and vertical. Did you intentionally make them wider or is that the way they are in a different year?

    Nicely done, sir and nicely edited. You must have gotten some puzzled looks while riding around with the front end boom attached(!) Question: What titling software do you use?

    To my way of thinking, any bike with tires no more than about 17" tall and a horizontal 4-stroke single that fits Monkey engine mounts is an equal player in the helmet cam game. Good to see some actual Viosport video, I had considered that rig. When 8GB+ memory sticks become practical, then I might actually buy one. That's one versatile rig.

    I'm in the NW `burbs of Metro Detroit. The vid was shot out near the GM proving grounds, during afternoon rush hour, on a Friday. I usually take the less traveled roads to get around traffic jams. On the edge of suburbia, there are still some unpaved sections. They've turned out to be a great way to make better time, who'da thunk it?:D It keeps getting tougher to find riding time here, too. Probably half of my riding involves using the bike to run errands, which isn't all bad.

    This bike is 12v (Nice powered) and sees 2-3000 miles annually. Everything has to be "real bike" caliber; I've no time or patience for things that break or don't work well. I tried the analog speedo thing first, that's why the bike has a 12v type headlight bucket. The results were unacceptable. I could live with a 60mph scale, but it had to be accurate & it wasn't. I sourced the smallest user-programmable unit available and built it into a junk speedo case. Digital gauges aren't may preference either and at $300 wasn't exactly an impulse item. If you want one, send me a P/M. The setup is dead-accurate and has a tripmeter a.k.a "CT70 gas gauge";)

    As for the bars, they're aftermarket, 6" wider than OEM, and long-since discontinued. If I could get more sets of them, I would. No, they're not "correct" for a purist resto, but this bike is a purist rider...not even close to stock.

    I do have to admit the guage isnt accurrate over 37mph. When I put my gps on the bike it seems to be very accurate up to about 37 but is off by nearly 2-3mph at speeds at 40, my top speed on the flats. If I actually broke down and put on a bigger motor or big bore kit then I might need the use of a dead-on accurate speedo but until then I'm satisfied with mine. Besides, if i actually made this a high speed/road worthy bike I'd have to do some other modifications for safety.

    What do you think of the stock brakes and drums? Do you think they're sufficient to not be necessary to upgrade for an upgraded fast bike? I've heard mixed reviews and I personally think they're sufficient. I've once had to slam on the brakes on a pretty steep decline and was going about 45+ and it stopped very respectably.

    Also,

    Have you noticed that the 1------2-----3----- recommended shift speeds on the original speedo are not accurate? I feel I'd blow my engine if I revved 2nd gear to its recommended speeds before shifting into 3rd and I dont feel 3rd gear could ever hit 60 without doing some serious damage internally.

    We probably ought to move this discussion to its own thread, lots to discuss. I suppose that technically, this is my thread. However, I did intend it to test the waters to see what kind of interest there might be in videos and share a few grins.

    I could live with 2-3mph off, especially if the speedo read fast. My NOS Nippon Seiki was off by 17% and there was no practical way to correct it. Electronic was the only way to go. The stock drum brakes, in proper working order, are okay up to about 50mph; so 45mph should be no problem. I wouldn't trust them beyond 55mph. You can "get away with" them on a 60mph bike, if you always remember to compression brake down to 50 before hitting them hard. My bike will easily crack 60 and cruise 55mph all day long; it has brakes and suspension to match. On warm days, I can be found cruising along in the low 50s with a stupid grin going. Setting up a CT do do this with OEM finesse takes some doing and isn't eveyone's cuppa'. What can I tell ya'...I'm not everyone. An accurate speedo is just part of a serious road bike. As funny as it might sound, calling a CT70 a serious machine, 55mph is still freeway/"real bike" speed. I'm too effing old to ride an unbalanced (engine power/suspension/brakes) machine in traffic:sad: A totally stock bike is slow enough (low 40s with a tail wind) to already have balance, except for the shocks.

    Stock OEM CT70 speedometers are only marked to 50mph and you'd have to rev the nuts off a stocker to go that fast. Downhill with a tailwind on a fresh motor that's been tuned to a razor's edge is about the only way you'd get an original moving that fast. Might sound scary but doubtful the motor would pop. These little Honda singles can easily handle 10K rpm no sweat. On the other hand, 60mph with stock gearing would have the motor spinning so fast that the stock clutch basket would grenade first. I do agree with you, however, about the upper ends of those gear range markings.

    I have a short video to contribute:

    Sunday drivers

    shot last autumn on one of the last sunny days riding my Z50 around the neighborhood.

    Just a brief test of a cheap camera (less than 30€ - the sound is more than ugly) mounted with a clamp to the bars (thus the annoying jiggle at higher revs). I'm currently working on a more stable fork mount.

    Thanks racer, i'll quit my questions in this section and start new ones if I have questions. Its just I'm so new at this questions seem to arise daily and seeing videos is even worse for my ever-questioning thought process (in a good way). Oh, the speedo does read 2-3 faster, which means 42 is actually about 39.

    mfro, sounds like you have some nice acceleration. I'd also like to add that I like listening to the motor nearly as much as seeing the vidoeo. One question, your bike sounds like mine and I have always wondered about that hummm of the transmission. Is that typical of these bikes? It seems somewhat exagerated from these specific bikes.

    These bikes produce a lot of strong vibration & impact shock. Mounting a camera on the bike is a challenge. A rig that uses a specifically designed camera such as makotosun's Viosport is about the only way. I use a "lipstick" camera fed into a mini DVD camcorder. The rider is the best camera mounting location. As far as a camera is concerned, the human body is a good shock absorber/isolator.

    A certain amount of transmission noise is normal. These trannies use all stright-cut gears; they're strong and mechanically efficient, but inherently noisy like a car in reverse (manual trans). If you think yours is noisy, you should experience some of the larger Chinese motors. Those gearsets can really shriek at speed, louder than the exhaust in some instances.

    BTW...I do understand about the flood of questions. That's natural enough. It'd just be better if they were posted in one of the other folders (tech, mods, general, etc)

    Racerx is right in that that straight cut gears are louder than helical geared ones (is that the right term in English?). However, mounting a camera to your bike can give you - through the noise on the video - quite some hints on anything that might be wrong with your bike.
    The camera, mounted to the structure of your bike, "hears" things different than the drivers ears. Next to no exhaust noise (shielded by the drivers body), mainly structure borne noise (another term where I'm not sure if it translates correctly?). There are a lot more mechanical noises on the video than the driver recognizes during riding.

    I also noticed that humming transmission on the video, and had a look into the engine the following winter. Found a worn primary gear which I replaced.

    If you want to listen to the repaired engine:

    The video itself is crap. A different try to mount the camera, its worse than the one I already posted. Listen.

    Definite difference, sounds nice. The description of a car in reverse makes total sense to me. Thanks all.
