Should I weld this weep hole?

The oil weep hole (red arrow) on the clutch cover never quits weeping oil and making a mess on the side of my bike. If I ride an hour, it will leak for the entire hour. Two hours, it will leak for two entire hours. And so forth.

I have put 1000ml of oil, but the bike has been sitting open for a while, and drained of most of what was already in there, so basically I could even have put more than that (it says 1400ml after rebuild). So there cannot be too much oil.

I rode the bike today for about 30 minutes, never too fast, never pass 3rd gear, so indeed the engine ran hot from turning around with not much airflow and on a hot summer Arizona day, but it cannot overheat that much.

I wonder if this hole should not be welded shut or partly shut. Partly shut would be better, I guess. I am tired of that oily mess, but the weep hole has a purpose, so shutting it completely may not be wise.

I am ready to J-B Weld the ******* shut but I'd hate to cause the bike to explode because of that.

So far, no coolant contamination to report, so the seals are fine.

Hi LeFrog
That should be sealed up but welding wouldn't be a great idea. It's not a weep hole. My model has a grub screw in there. I think it's probably only there to clean out the oil gallery that feeds the top end.
I used some loctite on mine. The weep hole is behind the hose @ 9 o'clock on the wp housing.

Well, maybe it is not THE weep hole, but it is a hole that weeps and the purpose of the weeping is probably to release some extra oil when there is too much, but right now it is a big messer.

By welding I don't mean TIG welding or anything industrial, but rather dropping a bit of J-B or even electronics solder, as it could be easily scraped out.
 
No, no, no what you have is technically a leak.
There should always be oil in that gallery but none should come out that hole.
As I said before a drop of threadlocker did the job for me.
Whatever you choose to use make sure you don't block the gallery.
 
I understand that, I did not intend to block the whole thing, just the hole.

THanks
