I hate to be the bringer of bad news, but you may have more particles inside the crankcase, and throughout your oiling system. I would recommend a total overhaul to properly clean out the engine's crank internally. Most likely your rod bearings are already suffering, hopefully they are "taking one for the team" and your crank is OK...

It's just another sad side-effect of sharing the crankcase lube with the primary chaincase oil, a HORRIBLE idea.

You are not kidding about the horrible design. This is where a real oil filter might have saved the day. I am not sure I want to put a 2 to 3k into an engine rebuild. It may be time to move on to a newer classic. I already have a 1969 TR6R that was my fathers bike I am putting back on the road after sitting for 24 years.

Sadly,
Zoltan

Nobody says you HAVE to, you could install a filter, flush everything really well, then live with the risk that SOME damage was already done.

Many people warn that a classic like that, which has sat unused for many years, is ALSO a ticking time bomb...

I pulled the clutch hub and the bearings look fine. There is no wear in the primary that can explain having metal in the oil after an oil change and 45 mile ride. Now it looks like there is something with the engine. I was thinking with 24k known miles is it possible the sludge trap is plugged or mostly plugged? Either way the case needs splitting there is something serious going on inside there. I guess ticking time bomb should be my forum handle from now on?

Thanks
Zoltan

Definitely check that sludge trap. I can tell you that from sad experience.
