    I just picked up this 160. I want to restore it. I have only been able to find new spark plugs and carb kits. Outside of that I could use some help tracking down sources for parts. Here are some pics of my project.

    I just got myself a CB160 that I'll be restoring this winter. I got it off ebay without a title (of course), so I don't know what year it is. Do you guys know if I can find out the model year from just the VIN?

    So I was working with my wife over the weekend, building a door for a shed we built. One of the boards in the door frame was a bit warped, so I used lap joints, and glued and screwed them, figuring it would flatten out when the glue dried. I needed some weight to work against the warp. AS I looked around the garage, I found the perfect weight: a CB160 engine and gearbox!


    Which got me to feeling sad, using that engine as a paperweight instead of blasting up and down the mountains. :cry

    SO I decided a little forced progress was needed, to get me back into the restoration mood. Since we had the woodstove going in the garage, I went back out after dinner, and decided to strip and paint t couple minor parts, so I could feel some progress. So I got out the wire wheel and stripped the swingarm and the footpeg bracket, and blew some flat black frame paint on them. That feels better! Progress! :D (pics to come!)

    I plan to go out and finish stripping the frame tonight! The wheels are already cleaned up, and mounted with fresh tires and tubes. Once the frame has a fresh coat of paint, I can re-assemble the swingarm, mount the back wheel, and by the end of the week, it will start looking like a bike again! That should give me the motivation I lacked when the weather was good for riding. Temps are hovering around zero today, so I'm not even slightly tempted to ride!

    My restore has been going really slow. I have not found any good sources for parts yet. I really need a tank. I think like you I might just start tearing it apart so I will be more diligent searching for parts.

    Send us some pics. For the very least to motivate us to get moving.

    Also if you have any restore tips please share them.

    Good for you getting back at it.

    The "forced progress" I put myself through last night has worked wonders for my motivation. Here are pics of some of the parts I've cleaned up, refreshed, or renewed, including: new tires, cleaned up wheels, tank side panels, speedometer glass, bezel and face, chain guard, swing arm, and footpeg brackets (with new rubbers).

    This is progress, and it feels good to get all these parts in one place, instead of hiding in the cabinet where they don't motivate me!

    The tank and frame are mostly stripped of old paint now. The rear wheel looks as good as the front. I've done little to the engine except clean it up at the car wash, and it looks great now. Most of the small sheet metal parts have been sanded, and are ready for new primer/paint. I've got lots of work to do on the fenders. The front, in particular, has lots of dings, but a hammer and dolly will fix most of it. I still have a big box full of parts that I haven't touched, though!

    What's wrong with your tank? I have a spare you could have for the cost of shiping, but it has its own problems. It appears to have been abused at the scrap yard. I bought it because it had good rubber pads, and one good chrome panel. The tank itself is pretty beat up, but it does not appear to be rusted at all. you could cut it apart at the seams, hammer out the dents, then weld it back together, if you are inclined.

    What other parts are you looking for? Between ebay, Bill Silver, and Honda, I've been able to find most of what I need.

    sweet I may take you up on the tank. Mine is dented too and I think the Petcock doesn't work. It seems the flow of fuel is not right. I mean when I fire up the bike it revs super high for about a minute then it comes back to a normal idle then when you ride it it quits idling. I am sure it is something with the tank and the petcock. I have been through the carbs and they are clean as a whistle.

    You have inspired me to get off of my ass this weekend and take mine apart. Thanks for the pictures. Nice work.

    More progress! The CB160 is starting to look like a motorcycle again, instead of just a pile of parts. Over the weekend I cleaned up the fork clamps, forks, and rear shocks. I finished stripping the old paint off the frame & fork lowers. I had not intended to do a bare-metal respray on this bike, as I intend it as a daily rider, but I was forced. When I started sanding, I found that there were three layers of paint on most of the bike: original white, later green, then black. The black was very poorly done rattle-can work. I envisioned riding the bike, and finding small rock chips all over that exposed the green or white paint below. I can't stomach the look of obvious poor paintwork, or many layers exposed in a paint chip, so I've been taking most parts down to bare metal.

    After some re-assembly work today, here's the current state of the bike:

    Darn camera is too good. Now I'm wishing I had dusted off the frame before I took the photos!

    Very cool! I bought a new CB160 in 1964 and rode it all through High School. I have always wanted to find a nice one to restore and watching this gets me thinking about that again. Here is a pic of a adventure ride with a buddy on his 305 Scrambler, we rode the last "Death Valley Tour". Got home late and tired after about 375 miles that day.

    Cowboy that is really really cool. You have inspired me to get to work. I have steel wooled the front rim. It is pretty far gone, but it looks soo much better. I will probably pull the motor this weekend. And I may pull it clear down to the frame. Did you spray your own frame? I don't have the place to spray so I will probably have to send mine out.

    I would like to make mine a daily driver also. It would be fun to go on a road trip as the previous poster stated he did. I am getting really stoked now. Once I do something outstanding I will post pictures. Please keep updating me on your progress.

    Thanks,
    Mike

    Here are some sites that have parts--www.westernhillshondayamaha.com and www.ohiocycle.com. Petcocks are no longer available new but you can find plenty of rebuild kits. www.groupwracing.com has a lot of resources and links to 160/175's.

    Hello adrenaline . I used to be a Honda dealer and mechanic but it's been a while. I have just started restoring a 1965 CB160 so I found this thread. I was reading your post about your idle problems and I reached back in time in my memory and I think you may have a bad advancer.. Either weak springs or it's sticky. It's also likely that you have plugged idle jets. The varying rpm would be the advancer and if the bike runs good hot but will not idle when warm it's probable you have a second problem with the jets. One other possibility is sticking throttle cable (s). If you un-do the slides be sure and put them back in such that the idle speed screw "ramp" is towards the idle speed adjust screw (s) . If put in backwards the slide will be 1/4 open or so when you start the bike. Great fun till it blows up! I don't think you described a petcock problem with the bike running ok down the road. I'm trying to work out casting up copies of the original plastic tank emblems for my bike that say CB160 using whats left of my emblems to make female molds. I've had some success but not quite right yet. Also I discovered that if bent a little from the sun they can be flattened with gentle heating and light persuasion. Is everyone aware how to straighten clutch/brake levers without breaking them even if they are pretzled? ..cheers... Dave

    Thank you. For years I did not think you could straighten these but 1 day I tried annealing one of these and it bent back just fine. I like to mount the cable end in a vise then play a flame from a propane torch back and forth on and a little past the bend area. After a minute or so put the closed end of a combination wrench over the "ball" and down to the bend. Carefully bend "back" maybe 1/3 to 1/2 the needed distance. Don't over do this. Dont know how to explain that last instruction. Re-anneal and repeat the bending. Every time you stop your bending to check your progress, re-anneal the metal or it will break. Hope this works for you. Dave

    can you elaborate on the advancer? I would like to check that out. I don't think the jets are plugged because I went through the carbs and I soaked everything good in jets. I would believe that maybe the throttle cables are the culprit but it is intermittent. Well it does it almost all of the time cold but it doesn't do it warm.

    My original thought was that it was leaking fuel out of the petcock and filling up the carbs and leaking into the cylinders then once the excess fuel is burned it runs right. Except that when it does idle back down it runs good but actually dies at an idol. I think I actually have two problems.

    I am going to try an use a regular gas can with no petcock and see if that problem goes away.

    Thanks for the advice and post some pics of your bike please.
