Ex21 losing power and shutting off

[JAXcrisp]

Well my engine started doing this last time I was home. I haven't been able to get into to see exactly what is going on but wanted to know if any of you have run into the same problem. Engine has less than 15 hours.

Oil??? Low?? Don't make sense. You done any mods to it?

I am. I am reading yours and it's saying," Tom is such a great guy. I realky should make a great deal for him on one of my treasured bikes.":laugh:

The oil is fine, and it's bone stock for now. I'm stumped as well.

 

[JAXcrisp]

Is should also add that it is only shutting off if it stays under load. With no load it will perk right back up

 

[buckeye]

Something is binding is my guess. But just don't make no sense.
What is it on?

 

[JAXcrisp]

This one is actually in my mudmotor

 

[buckeye]

Sorry, can't help ya.
Maybe someone will chime in.

did you try disconnecting the oil sensor if it has one? just to see if that makes difference.
could also be carb/governor related? you said idles fine.....dies under load right?

 

[JAXcrisp]

Yes I have disconnected the oil sensor but it didn't make a difference.
I'm with you I think it might be carb and gov related

clean the carb. and filter.

 

[JAXcrisp]

Yes I did disconnect the low oil sensor but it didn't help.
And it idles perfectly, just slowly dies under load but as soon as I take the load off it will rev up and run just fine

is it the long tail or short tail? if its a long tail it could be the pillow block bearings on the shaft

 

[JAXcrisp]

Long tail
