Rush-hour traffic allowed us to proceed at a more leisurely pace, and when the traffic thinned out I took to the back roads. Heading west on Lucas Valley road I was treated to more than ten miles of s-curves through cool redwood forests. Once I got out to the Nicasio Reservoir it opened up and I let her rip. She made sixty-five, but that seemed to be pushing it.
Symptoms
It seems that my carb adjustment to make the mixture richer had the desired effect. Even after prolonged periods at high speed she still accelerates through first and second just fine. Her idle speed does drop down to below 1k rpm though. If I'm coming up to a stop sign from a speed over 50mph, and I pull in the clutch and let her idle, she will die. Happened out at the reservoir yesterday, and again today on the way up to Santa Rosa. While that seems to make some sort of sense in my mind, I can't put my finger on why. Hopefully this carb rebuild will help.
To do today:
- Oil change
- Clutch cable adjustment
- Brake cable adjustment
- Carb rebuild
- Plugs
Wish me luck. Hopefully she runs better and not worse after all this.

Dang,
ReplyDeleteYou have exactly the same symptoms I have on exactly the same bike. Runs well, but sometime.... it just doesn't. After high speed it will die at the light. Cleaned carbs and all...
I have a an idle problem as well as backfiring and my carbs continually come off, assuming from the vibration. I can also tell the rubber boots are dry-rotted and almost certain this is the issue. Does anyone know where to pick up new boots and clamps?
