CB1100 Idle speed instability problem

[SportsterDoc]

Many views, some comments about bad fuel, nonsense in my country, only one solution, a whole trottle body replacement, under the second hand warranty, wich is one year in Belgium.




So I'm lucky that the issue exposed itself during that period.
Since the replacement back in June '16, the idle has been rock solid in all seasons and all conditions.

My dealer told me the procedure is that they inform Honda of a issue that could potentially lead to a recall after an investigation of the 'faulty' parts.
Thats why the dealer has to hold the parts for a certain period in wich Honda can investigate.

All this time I haven't heard anything from my dealer...either they didn't pick it up or if they did, they did't deem it worthy for a general or regional recall.

They replaced my throttle body on advice from a Honda dealer in The Netherlands wich applied the same method to cure the issue....

Be really interesting to know what aspect of the throttle body assembly was at fault:

1. TPS (not available separately...wonder if it removes easily?)

2. IAC (available separately) 16430-MJF-DO1 and common to CBR1000RR ABS, CBR1000RR, CB1000R, CBR1000S, CBR600RR, CB600RRABS, Cb500F, CB500X... https://www.bikebandit.com/oem-parts/det...sch=848000

3. Throttle bodies not seated to intake (anyone snug the band bolts?)

4. Vacuum leak, such as a crack in the 4 way or 5 way vacuum tube fitting

5. Fuel injector(s)
