Leaving it on the sidestand and troubleshooting it starves the cam for oil. If you're gonna be leaving it running while you study it, get it as close to vertical as possible and if you're gonna be running it very long, a fan blowing on that air cooled motor isn't a bad idea.
The RPM related clanking makes me wonder about something in the exhaust.
Instead of the screwdriver/stethoscope, try a piece of plastic tubing. Not recommended for contact with too scorching hot surfaces.
A piece that fits in the ear and a metal rod shoved in the other end can be handy. I have an old stethoscope that I shoved a rod into. They are cheap. And a mechanics stethoscope isn't that much, either. Pardon me for saying it, but, it, Sounds like you could use one.
If you could get the guy who sold it to you to be honest about what he had done to it before it started doing that, you might be ahead.
I don't understand why anyone would step off into
Bobbing a Savage and leave that turd of a muffler on it..
I sat on the bike while recording with my phone on the right hand and moving it around, can't really remember where.
Bought it from a friend who got it in a trade, all he could say is that the PO had replaced the cam chain. It had a straight pipe when I bought it, and there was a clanking then too, but maybe it was slightly different. I have to check the exhaust and buy a stethoscope. Haven't really dared to rev the engine due to the noise, but it seems to be louder at lower revs. I haven't driven it yet, either.
The timing is correct AFAIK, the marks on the cam shaft end were vertical when the left side plug hole mark was lined up with the crank shaft marking.
The upper con rod bearing is the piston pin, right?
