TT500 wet sump problem
Posted 24 May 2012 - 09:23 PM
Do these bikes have a check valve anywhere? I looked through my Hanes manual and it doesn't list one.
If they do have one, can someone let me know where it is located and if there is a rebuild kit available? Should I replace my oil pump?
Thank you in advance!

I had the same prob in my bike leaking oil from this worn seal and making it a wet sump motor over night etc .
worth a check you will have to remove the clutch cover to see the seal i am talking about its about the size of your little finger nail

Same as your BSA, it's a common problem with XT/SR500's too. I guess all dry-sump engines now and then.
I don't know why the oil check valve is included under contact breaker/governor on this page....but here it is. It's parts 16,17,18. It's a spring, a ball, and a seat located just to the left of the oil filter hole. If you look at your right engine case there's a small round lumpon the case just to the left of the oil filter cover....that's where it is. You have to remove the case but then it's just a few minutes to install. I think a set it is about 15 bucks.
Usually when it happens to me I check the oil with the bike cold and discover low oil. So I top it up and the bike starts blowing smoke because it's overfull.
The XT500 manual says to check the oil, start the bike, let it run a bit...and then check the oil. I guess they do that for a reason. I don't worry about mine anymore, sometimes it leaks, and sometimes it don't. I'm just careful not to add oil until I've warmed it up and then checked the level. If it has wet-sumped I just wait a few minutes and the smoke goes away. It's never harmed it in 30 years.

I think that I'm going to keep my eye on it for a little bit and if it keeps smoking and doesn't clear up after I warm the bike up I will have to go in and change these.
Tonight I have fork seals to finish!
