My CB750 parked out front of Colorado Moto Service, ready to head home.

I got my 1980 Honda CB750 Custom back from the shop Wednesday and it’s running great. But I’m totally baffled.

I took the bike over to Colorado Moto Service specifically to finally get work done to stop it from smoking like crazy whenever I fire it up. It’s been doing this for years and lately had gotten a lot worse. Spend the money and get it fixed!

Well, I took it in and they told me they were not seeing any smoke. How could that be possible? I had all kinds of theories: Maybe the guy would just fire it up and hop on and ride away, thus leaving all that smoke behind him and much more dispersed. I don’t know. But I was determined to start the cold bike myself and then have them watch while it warmed up and started producing blue clouds.

So I told Judy not to leave as soon as she dropped me off–she might be taking me right back home while the bike stayed there. And I didn’t tell them I was coming so they couldn’t “get it ready” for me by warming it up in advance.

The mechanic who worked on it was very nice and totally deferential: “You’ve had this bike a long time and you know it better than anybody . . . ” And I was determined to show him what he should have seen immediately.

I threw my leg over and laid my hand on the engine to make sure it was cold. It was. I set the bike upright, turned the key, pulled the choke, and pressed the starter button. It turned over nicely but didn’t catch and he realized he had the gas turned off. So, gas flow enabled, I pressed the starter again. It turned over and caught. I told him now to wait a moment because the engine had to warm up before it started burning oil out of the cylinders.

And we waited, and I revved it, and it ran nicely . . . and it never did start smoking. Never. I just have no idea what to make of it.

But that’s OK! If this issue somehow mysteriously solved itself now, finally, and I don’t have to pay $1,000 or whatever to have it fixed I’m fine with that. In the meantime, they synced the carburetors and the bike is now running like a champ. Plus, miraculously, while they had it, the ignition switch developed a problem (what better place for that to happen) and they diagnosed that and fixed it. Heaven forbid it had happened to me out on the road.

And I got out of there for less than $600, whereas I was sure I was going to be paying about a grand more by the time they finally found the problem I had taken it in for.

So now there’s just one more hurdle to pass. It’s parked in my garage now but the next time I take it out to ride will it smoke? If it does I have only one theory: they parked it on the side stand and I always put it on the center stand. Is it at all possible that that somehow makes the difference in oil getting somewhere it isn’t supposed to be? If that happens heck, I’ll just start parking it on the side stand. Problem solved.

I’m going to be very curious to see what happens.
