Another High Idle Problem

MPI = multi port injection or commonly known as fuel injection.
ATM = automatic transmission/ transaxle.

Ah! Okay, thanks for helping me with that, Peter.

Follow-up on my fast idle fix. Short rides each morning since re-setting the ECU as per Peter Baron's guidelines. Bike always goes to about 1600rpm for a short time after start-up, then consistently idles at 1100rpm after that. I will let you know in another week how it is running, but it is getting too hot to enjoy riding now, so I won't be posting much until the end of September. I am very happy and relieved to have my bike running (and idling) like it should be again.

Ok, cold start up and higher RPM according to the engine temp seems normality

You should see the CB1100 RPM on a -25C winter morning. It will idle quite high for at least five minutes before eventually settling down to operating idle after 10 minutes. No ECU reset ever required.

Profuse hot, humid summers off-ramping after long freeway run tended to idle in the opposite direction as the engine and fueling gasped for cool air. Idle sometimes dips below 1000 before eventually recovering to normal idle rate.

Don’t remember when we had - 25*C in the GTA… and starting any of my CBs would qualify as a harm

Every winter [url=http://cb1100forum.com/forum/member.php?action=profile&uid=3454]PB. You'd know when you go for a ride.

This was the last time I started an engine in those temperatures. Thule, Greenland, 1960. No motorcycles, but that old Dodge was a lot of fun on the ice. My bike won't see anything close to freezing where I live, but I'd rather ride in 35F than 95F. I can put on more clothes, but folks get all excited and mean when I start taking them off, for some reason. As I write, it is 101F, and the bike doesn't need much time to warm up.

Amen. Cold weather riding is more manageable than ultra hot, though, you might need to deal with road salt (or not - just leave it for spring).

I deal with heat better than cold, or at least did until I got electric gear. I HATE cold. I froze on the 60 degree days on the ND trip and had to borrow a sweatshirt, was comfortable on the mid 80degree days and kinda warm on the day it hit 102.
