Ditto from Canada,
Stig, I know you tried sea-foam but I wanted to suggest a product marketed specifally for cleaning fuel injection systems - any one of them should do. Please forgive me if your sea-foam is just that.
Also, have you tried dropping in the old copper spark plug? Just a troubleshooting step from your friendly neighborhood computer tech.
All else fails make the dealer fix it!
Hey Canada & Other Friends,
SYM fellow suggested these were symptons of a failing coil.
Replaced it tonight (NOT fun - mounting screws on the outside of frame member - against body panels) - didn't help - same severe stumble at 20>35MPH.
Have been thru 3 plugs & 3 tanks of SeaFoam this week - no improvement. Done everything I can think of & I'm out of ideas. Something quit working last week an hour into a ride.
This is my 4-season work commute car. After only 7000 miles.... - I need reliability to get me to the end of my 30 yrs & retirement (3 yrs away) of my second career. (yeah, OK I put 6K of those miles on it goofing around at sunrise with the rabbits)
I love this dumb scooter.
Hard to think of giving it to the dealer for several weeks & walking & riding the city bus again
when it's not actively snowing!! You ever sit on one of those pretty Repsol CBR250's or the new CBR300....cheaper than the same size scoots! And it's a HONDA....
But I love this dumb scoot...
You guys are something else....
Stig
