Picked up an 83 as noted for $75. Not expecting a miracle but just something I was interested in to replace my 500. This bike ran well then started to run rough (as per previous owner) then sat for 2 years. So, front tire flat (valve torn), rear calipers stuck and we rolled it slowly onto my trailer.
My son and I squirted some oil into the cylinders, drained and then sprayed out the carbs, drained and replaced gas and added some Sea Foam, cleaned plugs and then cranked. Apart from a sticking starter switch, fired right up. There was lots of noise from the rear bank and that increased with rpm.
We opened the cover, regapped at .005 as per the Clymer manual (they did seem a bit tight), made sure everything had oil and tried again. Still, that noise that did sound like loud valve chatter but not quite.
The rear of the #1 lobe had scoring but the contact end seemed fine as did the #3.
Reading through forums, I noticed a .006 gap revision had been issued from Honda so I regapped at .006 (or maybe .0065) and tried again. Still that noise.
Probably worn lobes but maybe a tensioner issue?????
I have attached a link to a youtube video I posted and that noise is evident. During the middle, the camera is pointed away from the bike so that the mike is pointing at the sounds.
Any tips would be appreciated.
