Odd Idle

2015 Fjr1300 ES with 25,000 miles. Bike runs great never misses a beat until the other day. After a blast to triple digits for a mile or so on the freeway, got off and after coming to a stop the idle was
erratic going up and down a few 100 rpms. Light turns green, go a couple of blocks to the next stop and idle settles down to normal. I haven't done a throttle body sinc in a while. Do you think thats the issue?

Is your fuel fresh? If not, put a couple ounces of Seafoam in it... in case you have some moisture in the fuel.

The ECU controls the idle.... a feature of the throttle by wire is ECU will increase rpm slightly as you let the clutch out that first little bit... to prevent stalling... but that should only be 50-100 rpm. Just be aware it's there.

Iam the original owner so Iam aware of the uptick in rpm when the clutch is released from a stop. Looking back, I think you nailed it. After an hour or so the arthritis in my left wrist gets pretty painful and I probably hadn't pulled the lever in all the way necessary. Next ride we'll see. Thanks for your response.

Happy Trails
