The Christmas Eve Ride That Wasn’t

The bolt on the right is a drain plug and the left is the filter. They really shouldn’t have been this oily.

December 24 was very warm and the ice had finally melted off our street so I wanted to take the Kawi for a spin. I geared up, rolled the bike out and started it, and when it was warmed up I got on and headed out.

I got about 10 feet out of our driveway. Then the engine died. I started it again and tried to move forward and it died again. I tried a number of times. Finally I rolled it backward to where I could go forward into the driveway, revved it up, and managed to get right back where I had started from a few minutes earlier. What the heck is the matter?

What’s that funny red thing over there? Oh, an ear plug that fell down on the engine who knows when.

I’ve been riding this bike for 21 years now and I’ve got experience with it. This seemed similar to something I had encountered a long time ago. You have to understand the Reserve lever on this bike. It has three positions: On, Reserve, and Prime. Normally you run on On, flip to Reserve when necessary, and I have never really known what you would use Prime for. But I know what happens if you move that lever to Prime. It drips gas into the cylinder and if the bike is not running it will continue to drip and that gas will seep past the valves into the oil pan. Motorcycles do not run well when you have gas mixed with the oil.

Yes I know that from experience. And this seemed to be acting very much the same way it did when I inadvertently left the lever in the Prime position. So how to confirm this diagnosis? Change the oil. That’s a major pain on this bike because you have to remove some of the bodywork to do it. Guess how I spent a big chunk of my day on December 24.

Of course it wasn’t all that straightforward. Things have to go wrong, don’t they.

I had wondered since I had the bike in for a tune-up whether my mechanic had put too much oil in. Looking at the sight glass all I had ever been able to see was black. The Concours is supposed to take a little less than one gallon of oil so I knew if what I drained out was too much to fit into a gallon jug that there was an issue. But that could happen either from over-filling or gas dripping in with the oil. Not sure which it was but I definitely couldn’t get it all into a one-gallon jug. And once it was drained I could see into the sight glass–it was no longer just black.

All this crud was stuck on the under panel, I assume because it had too much oil and was throwing it off.

So I put new oil in, checking repeatedly as I poured to see when the sight glass showed it was enough. But I must not have looked soon enough; it always looked the same and I kept pouring oil in. When I concluded this had to be too much I looked hard at the sight glass and concluded that it was full of clear, clean oil. I had put too much in.

I needed to drain some out, but I didn’t want to drain it all and I didn’t have anything clean of the right size to catch it all. So I got a glass jar and tried to drain some into the jar without spilling a whole bunch. I was not successful. It didn’t all pour out but I had really big mess on my hands. Things have to go wrong, don’t they?

At this point I was sure I had drained enough but the sight glass still showed full. So I started the bike and ran it for about 30 seconds and then let it settle. Hallelujah, it was right where it needed to be, and I could clearly see the oil level.

Then I cleaned up this entire mess. Finally I started the bike. It started and ran beautifully. I got on and eased out of the driveway. It ran beautifully. I went just around the block and it ran great so I parked it. That’s all the riding I did that day.

So I guess I must have screwed up. I knew the bike was nearing Reserve last time I rode it so I must have turned that lever the wrong way. And while I already knew what happens when you do that, I’ve just had my memory refreshed.
