So It looks like these M8s have a potential flaw that seems to show up more when ran at higher RPMs. So I guess the wise thing to do would be to run them easier and stay away from the limiter to try to limit the possibility of sumping (though it still may happen) or put the pump seal on and hope for the best. If that's not acceptable, then deal with the consequences or get a different bike.

 

That's about right. Pretty sad when a brand new bike costing $20-45,000 can not be operated as it was designed to. Maybe the better approach would be for Harley to drop the "redline" on the tach to 3500 rpms. I suspect that would eliminate ALL reports of sumping completely.

 

I think this would take care of my problem, LoL

 

Can someone take a picture of the crankcase trigger if they have the misfortune of having to remove it. Would be helpful to those of us who have yet to sump have more confidence if we have to pull the trigger.

modified an old m/c saying......there are 2 kinds of M8 owners, those that have slumped and those that will sump.

I agree it is sad. But I would rather take it a bit easier and keep the bike going down the road than sit around crying because my bikes in the shop with a fuked up motor. It's not like these things are performance machines anyway. No power and heavy as ****.

 

No....not what I mean. The procedure that has been discussed was remove the Allen head bolt and pull out the sensor/trigger. I took that to mean that there was something occupying the space immediately adjacent to the Allen bolt. Am I missing something? Do you drain the oil from the Allen bolt opening and then pull the sensor from the adjacent tubing material?

I really dont know. Hope to never have to find out.

 

3/16 allen bolt holds the sensor in, remove the bolt and pull the sensor down, when done push it back in and put allen bolt back.

 

That may be for some. I don’t ride my RGU any different than I’ve ridden any other bike. If it breaks it breaks. So far, it is rock solid.

In early July I’m riding it from LA to central Maine, and back. Should be over 7k miles. I trust this bike totally.

 

Thx...that makes sense.
