17000 miles and just riding down the road in 6th when the speedo went from 60 to 0 then only 5th and 6th gear what is harley making junk ..always had an off and vibrate think i found it maybe ???

 

no vibration from lugging more like coasting in 6th vibration was in lower gears

 

sometimes the vibration would go away for a week or so then come back for maybe a day,,,, this is flat road riding in the hills i never use 6th ..too many rpms most of the time...4 back tires in 17000 miles & two front.... wife thinks i should slow down... lotsa luck honey

 

It sounds electrical.

Check the easy stuff first like fuses and loose wires.

When it acts up is it especially hot out or does it do it at any time?

 

thanx finally someone thats not rude ..i have tested all the electrical ,,most of the techs at hd around here felt like there was excess vibration but when the factory rep rides it and says its normal i just rode and didn't worry...now the shifter just hangs there...trying to get the factory to cover it ...seems like something just fell off

 

On the shifter, you can remove the top cover on the tranny and see if maybe the spring on the pawl has broken...did you say it was stuck in gear?

Don't want to make you think your ECM is going bad, but I had some speedo issues and spitting / coughing that I could not find...right before the ECM went out.

I replaced with a Thundermaxx so it was a good excuse to spend $1k!

 

I'm not rude. I see you are from California.
