2003 BIG DOG CHOPPER KNOCKING NOISE FRONT OF PRIMARY

[BUCK181]

PLEASE HELP, A KNOCKING NOISE IS COMING FROM THE FRONT AREA OF THE PRIMARY, FIRST THOUGHT IT WAS A ROD BEARING, BUT YOU CAN LAY YOUR HAND ON THE PRIMARY AND FEEL IT, TOOK COVER OFF AND CANT TELL ANYTHING. ANYONE ELSE HAVING THIS PROBLEM?? PLEASE HELP!!!

By "cover" do you mean the inspection and/or derby covers or the entire outer primary?

Could be compensator sprocket, mine was making noise like yours and ended up springs had wore through housing inside

 

[BUCK181]

WHEN I THOUGHT IT WAS A ROD BEARING, IF YOU LAID YOUR HAND ON THE ENGINE BLOCK,YOU BARELY FEEL IT, BUT YOU CAN LAY YOUR HAND RIGHT ON THE FRONT OF THE PRIMARY WHERE IT BOLTS TO THE ENGINE, AND FEEL IT REALLY BAD!!! SOUNDS TERRIBLE!!

I bet its either the compensator or the stator. Pull the outer primary cover and see what you got.

THANKS TO ALL FOR THE REPLIES, I WILL CHECK THESE THINGS TOMORROW AND LET YOU KNOW WHAT I FIND!!

OK, GOT HOME FROM WORK AND PULLED THE WHOLE PRIMARY COVER, ALL LOOKS GOOD AND FEELS GOOD, SO I CRANK THE DOG WITH THE COVER OFF, AND NOISE SEEMS TO BE TRAVELING DOWN THE CHAIN FROM THE REAR TO THE FRONT, I CUT THE BIKE OFF, AND YOU CAN MOVE THE RING GEAR AND CLUTCH ASSEMBLY BACK AND FORTH,(FRONT TO BACK OF BIKE) ABOUT A INCH EITHER WAY,IS THIS NORMAL?? SEEMS THAT IS WHY IT IS MAKING THE NOISE, WHAT DO YOU ALL THINK??? I AM LOST.

Go buy a stethoscope at Harbor Freight tools and try to locate the source. If you think it's under the primary cover just drain and pull and have a good look. Could be as simple as a chain adjustment.
