CB1100 Idle speed instability problem
1. MOST common mistake in trying to "repair/find" problems is replacing parts, more parts... or complete segment/ass-y prior diagnosing. So even if the presumed problem is fixed with guaranteed 100%, no one knows what was wrong.Angry
2. Watching 5 min video clip/idle up and down tells me what tach is doing, instead of where eventual problem is located.
3. Most members are not troubleshooting oriented (normality, they have their skills in different fields), so a lot of the information they provide is of less or no value
4. WHAT tech would love to know prior making decision is : actual reading report when it occurs (RPM, temp, V, Amps, injection time++++ = service data live stream, DTC status = history, pending or active, freeze frame data, when/how it happens...long, short rides, almost warmed up, only hot, how often...once a month... ANY modifications done to your bike ( PC, bypass O2 sensor, electronic or/and MFI related mods), any work already done to your bike in regards to this problem...
5. Would be excellent if tech has long Honda motorcycle experience and is electrically smart. Techs are people who would like to face the issue in reality, touch it, instead of having describing/filming/narrating it by members
5. Hope this RPM/stalling issue is not related to upcoming ECM update/reprogramming/recall/campaign by Japan HMC
6. If problems are not common, is more difficult to find/rectify them
7. Hope you ride your bike often , not 500 miles/year, use FI cleaner and fuel stabiliser for LONGER storage - not necessarily winter storage
8. How many members did visit HONDA or qualified service center and speak with tech personally??
9. The bottom line is (I know is not easy/simple): diagnose it right and fix it at the first time

This is NOT or about to criticize anybody's/members effort in finding problem but to provide more essential/valued technical info.
Hope this GENERAL info will help to understand the complexity in finding MFI/electrical solutions (not only TPS)
