2007 K12GT Woes

I have been plagued for years with the intermittent stalling issue. I have just learned to live with it. it always starts right back up and then doesn't return for some time...well, now is the time. Has anyone here have any ideas on things to check?

Symptoms: runs nice and smooth for about 10 -15 miles, then will stall out, it doesn't start back up like it did before....it takes a lot more finagling to get it running. When it does start back, it runs very rough almost like its missing....

My findings: Only code via GS911 is tank vent valve??? but it wasn't present this last time. I don't think ignition coils show up via diagnostics.

just wondering if anyone here has had similar issues...and before you ask, all recalls and updates have been done. I was thinking about ordering a Booster Plug to see if that would help at all.

Thanks all!

I cannot be sure I understand exactly what is happening, but if the engine is cutting off when the bike comes to an idle, then checking the idle control valve and cleaning it is worth a try. The idle control system also includes some hoses that should be checked.

Thank you sir, I will give that a look this weekend

Have a look at the AF-XiED unit instead of the Booster Plug. It provides a permanent adjustment to the AF mixture, which the Booster Plug won’t as the ECU learns to adjust to the altered signal provided via the BP.

Did the updates include the airbox?

Yes

I knew a girl with a 2011 K1300S and her bike had the same problem.
The shop was not able to fix the problem and she had to get rid of the bike.

So far I'm batting zero on helpful replies

I’m giving you [emoji817] on replies though! Thanks Lee

Installing the AF-XIED on my 09 K13GT didn’t do anything to take care of the engine stalling
It did help with a mid range flat spot

Did you check/clean/replace your tank vent valve? Is your fuel cap venting properly? Sounds like you're starving for fuel.

My 2 cents.

A buddy's K1300GT had a similar problem that was ultimately solved when his mechanic reset the adaptations. You can do this with a GS-911 and probably the Motoscan app as well. Can't hurt and cheap to try if you have one or know someone who does.

A buddy of mine fitted a Booster Plug to his bike and it was a very temporary fix. After a couple hundred km the issue was back.

Thank you BC100S and RadioFlyer. I’m planning on checking the vent valve and tank line. I will also reset the adaptations with GS911. Hopefully some time tomorrow to do all those things!
