CB1100 Idle speed instability problem
(05-17-2022, 12:23 PM)max_imp Wrote: As you may have read some lucky members have permanently fixed their issue with a software update, not possible in the us, e.p.a. is a scary thing so the dealers are not prepared to risk their business i believe.

Every single cb with this issue ( mostly the 2014 models ) started good as gold but something changed over time and we never saw any wear or dirt in the valve body, so what gives?

And i don't know of any member who did not have success with a new iacv, to me it is the lack of control from the ecu,
( hence the software " update " ) i think the older iacv's permanent magnets have degraded to the point where they no longer control the iacv correctly.

A lot of times this has happened after the engine has been very warm, permanent magnets lose magnetism if the temperature rises, the iacv is in a hot place and that is why i have come to this conclusion.

You may be in a unique position to evaluate the " magnetic torque " difference between an old and a new one firsthand.........

Haya Doc.

Hiya, Max!
Glad you responded.
Sold my 2022 Triumph Street Twin after 10K miles in 10 months.
Looking for another XT250: Easy to work on with a grandson and he then can inherit.
