Nice. The Honda dealer in my town had one of those displayed in the window when they first came out. Is yours an 8-speed like the originals?

I would get some clamps on that braided hose. Rubber stretches over time and that snug fit will no longer be snug and will come apart (at the worst possible time).

This truly is an amazing find. I personally hope that it ends up in a museum where it belongs. Its beyond perfect. If its in a museum then maybe there is a chance I will get to see it one day. Good luck to anyone here who might be bidding. Only a few hours left and the reserve has been met.

That's the problem with these time capsules that show up every so often. What do you do with it? Pop its cherry and the value drops like a rock. Better off just buying one with low miles in very good condition for half the price if you intend to ride it. Even the present owner is shaming anyone who wants to actually buy it to ride it. As an investment I believe it will at least hold value and keep up with inflation. Use it as "man room" decor and a conversation piece until you sell it in 10 or 20 yrs?

That bid price is well below 1989 MSRP with inflation factored in. Mount some new tires and ride off on the new CB-1 you always dreamed of back in the day.  Grin

Looks like you already got some good advice on sorting out the engine. Once you get it running well: Don't go too far or too fast on those old tires even if they still hold air. That rubber is hockey puck hard now and not safe for leaning into a corner or panic stopping. Not to mention you will feel every little pebble you ride over. New sport tires ride sooooo nice.

Open the bleeder on the caliper and cap on the reservoir and pump out the old fluid with the pedal/lever. Before the reservoir goes dry (don't let it suck air!) fill with new fluid and pump until the new stuff is coming out the bleeder. (If it looks real nasty or has debris in the reservoir turkey baste out as much as you can instead of pushing it through)

 Check the chain for slack and tight links. The factory grease in the o-ring chain internal links gets old and hard with age with no practical way of relubing. I would expect the chain to wear out fast and start kinking once you start putting on some miles so plan on a new one. I prefer non o-ring chains myself but they are a little noisier and require periodic lubing but will last a very long time with care and rob less HP because there is no rubber o-ring friction.

Wouldn't hurt to change the coolant. Pull cap off. Drain bolt on the pump and two on the front of the cylinders. Refill with 50/50 and start up and let idle with cap off, keep adding more coolant until the system is full. Make sure overflow tank is filled to the line when cool (kind of hard to see when the plastic gets old and cloudy)

Good idea using foam for the air cleaner. Should breath much better than that restrictive paper element. Might lean it out just a smidgen though.

Yes. With a 4cyl bike like this you have to find the sweet spot on each cyl.  Gotta think of it as 4 individual 100cc engines sharing a crank. The carbs have to be tuned individually and then synchronized with each other using a mercury meter so they work in unison to do an equal share of the work. Can lead to a lot of back and forth until you get it right.

 In a perfect world we would each have a spare set of headers with O2 sensors on each pipe and a synchronizer hose on each carb so we could tune for the perfect fuel/air ratio throughout the rev range but as it is we have do it with a little old fashioned science and back yard mechanical skills.

 Some folks like to use an infrared thermometer on the headers and fiddle with the carbs until they get the temps to show  + or - each other within a few degrees. As the bike warms up do these differences change? Back to the drawing board.  Angry

When you blip the throttle does your tach needle slowly drop back to the set idle?
 You're too lean.  Does it drop below the set idle before coming back up? You're too rich. Some guys like to "read" the color and amount of carbon on the plugs.  There's a lot of little tricks like that. Most will have you running in circles if you're a perfectionist. My next bike WILL have EFI.  Cheesy

You're a man who isn't afraid to tackle unpleasant jobs, I'll give you that.  I used gas proof o-rings instead of the (very expensive at the time) preformed ones for the float bowls when mine leaked. Just give them a light coat of silicone grease and push them into the groove as you work them around the corners.  Still holding years later.

The slight wandering idle may be do to typical emission leaness. I found 3 turns out to be the sweet spot for a nice steady beat and off idle throttle response but with factory exhaust you may find 2-1/2 to 2-3/4 to be better.  If you didn't grind off the stop tabs from your float bowl covers while you had them off you're limited on how far you can turn the idle screws in or out.

You lucked out. I had a few tight clearances on my first valve check. Second time everything was within spec. Many times you can swap around shims without even replacing any. Have a notepad, pen, egg carton, and calculator handy. Organization and patience is key. One of those jobs where you wish you wouldn't of slept through H.S. math class.  Grin

How do you like the higher gearing? Nice having a little more space between the gears and a bit of an overdrive, isn't is?

Is that still the stock muffler? I replaced mine with a Kerker slip-on soon after I brought her home in 1990. I run it with no packing now and as long as you don't rev it too high around town it is still low tone and tolerable. On the back roads winding her up into the meat of the powerband and hearing that exotic Ferrari sounding shriek overpower the wind noise is soooo sweet. Jekyll and Hyde.  Grin

Two mechanical jewels that were not well received by displacement hungry Americans when they were first sold here. Hard to believe that even the "modern" bike is almost 30 yrs. old.  Shocked

Beautiful bike and scenery. Snow and bitter cold here. Cry  The CB-1 does have nice wide powerband for a .4 liter bike. Doesn't hurt that the stock gearing is like a farm tractor.  Cheesy

The wheels I've seen painted black look great.
14  General Category / Tech Corner / Re: Why the countershaft speedo drive? on: December 18, 2017, 02:59:55 PM
The speedo reads about 10% high on average. If you trade out the stock 41t rear sprocket for a 37t like many of us have to make highway runs less frantic you will be about perfect on your mph gauge/true speed calibration.

8 rocker arms per cylinder just to get that perfect valve arrangement Cheesy  Honda engineers were on top of their game back then.
