High RPMs issue
High RPMs issue
Hello fellow Harley people,
My bike started having an issue yesterday that Harley and myself cannot diagnose as of yet.
It began with high RPMs at ignition, which has never happened before. I've had previous bikes where the RPMs are high at ignition and then slow down after the engine warms up, but my Harley has never done that.
After riding for about 10 miles and exiting the freeway the RPMs stayed high with no regeneration. Downshifting was not normal because the RPMs didn't drop. When I came to a stop the idle was over 2000 RPMs and then after several seconds it dropped suddenly to the normal range.
When I took it in to Harley I experienced no problems the entire time. They checked the throttle pin and cable tension. Everything checked out okay and I had no problems on the way home.
Today I was leaving school, and just like yesterday there were high RPMs at ignition. Functionality was normal until exiting the freeway, and just like yesterday, the RPMs were high with no regen.
I bought this bike brand new last year and have over 17,000 miles on it. I take very good care of it and keep up on all the servicing. Does anyone have any idea what is causing this issue?

Check the throttle tension screw/**** under the throttle grip and make sure it's loosened correctly. If you're good there, take it back to the dealer and use your warranty. Leave it until it's repaired.

I've encountered this problem and dealt with it for a long time on my '13 Super Glide Custom. I have around 18.5k miles and just recently I've also had problems with high idling on hot start ups. Last weekend I was on a ride and my engine died on the highway. After removing the battery cover I found the negative battery terminal was melted. My girlfriend and I were wearing heated gear and I thought maybe we were overloading the battery. Then someone at Harley told me a loose battery connection can cause excessive heat and that can happen. I was also told that would explain my engine issues that day.
I put the bike on a tender and found it was running perfectly for the next three days. No engine malfunction, and no V INERR on start up. On day three it was left off a tender and all the symptoms returned, minus the engine failure. I concluded it was a battery issue and bought a new battery. I also read several threads about the V INERR code and saw that many people think it is associated with a bad battery cell, or poor connection somewhere. It's been a few days and so far there has been normal engine performance and no V INERR error. I'm not sure if the new battery took care of everything or not, but so far so good.

After a year of dealing with this error I may have unintentionally solved it. I was installing new mini ape handlebars this past week when I had to mess with the main wiring harness connectors. After uninstalling my heated handgrips and literally squirting dielectric grease in every connection in the fork tube under the gas tank, I have not had this VINerror code pop up once, even under ideal circumstances. It's been about 10 days so far. I'll make an update if I get the V INERR code again, but so far so good.
