Thumb 85 xt600 project bike

Hi guys, I've been lurking for a bit to see what you've been up to on your xt600's. I just bought one about a month ago. Runs strong with 16k miles on it.

It needs a little work, but I'm getting there with it. So far I've replaced the fork seals, front pads, signal switch, rear tire and now I'm fixing an oil leak at the cylinder base gasket. I think it was the o-ring that was pinched around the cylinder that was leaking, but since I was there, I replaced the piston rings and valve seals as well.

I'm noticing a wet spot on the inboard side of my oil tank. I guess they do rot under that insulation they put on the tank. Anyone suggest a repair or should I find another tank?
If anyone has a spare they don't mind parting with, I'll be happy to take it off your hands.
I'll take some pictures of the latest repair work and post them up.
I love this old xt, thing is built like a tank.

Which side is your base gasket leak on? If right side Its probably the gasket that seals where the oil is pumped to the head. Its a round collar around the oil hole. It does not come with a top end gasket set. If its the left side The gasket leaks around the cam chain tunnel. There are only a few 10 mm bolts and I have replaced mine about 5 times . I couldn't stop it , good luck. THe oil tanks can start to leak where the mounting taps are brazed to the tank. They are available on e bay. Or you can rebraze it ,or just use JB weld.

Gotta love the "known issues" trials and tribulations. I bought a complete gasket set, so I did get one of the rubber collars. Should've siliconed both sides of the gasket, that might help in the long run. I already bolted down the cylinder.

It looked like it was leaking rear center of the base gasket, but the gasket didn't look bad. It could've been wicking along from the sides. Previous owner siliconed the cases to try and stop it, so it was hard to see where it was coming from.

I'll try some jb weld for now on the tank since I don't have a torch to braze it and I'll keep an eye out for another tank.

I saw another xt selling in my area, but was too much based on the condition of the bike. I wouldnt mind having another to play with.

Thanks for the tips

It can go by rings , it can Go through the block breather into the air box after the filter and get reburned. It can leak through the valve guide seals, but would smoke briefly at startup after setting overnight or longer. I would do a compression leakdown test and check you rings. Just giving you my 2 cents.
I bought my '90 with the baffle already removed and I've had no oil issues either with that set up, or with an FMF pipe.

86 XT600 baffle

I was hoping for a used one, I can get new from Yamaha but very expensive. I may have to bite the bullet anyway.... I do not know where mine got off to.

On a different forum somebody suggested the intake manifold (the rubber thing between carbs and cylinder) could be dead. I've sprayed deodorant and brake cleaner around the manifold but this didn't change the idling speed so that doesn't seem to be the problem.

The problem pretty much appeared over night.. anyone got an idea?
anyone?

Check your air screw, Its acutally a fuel screw. Set it at 2 1/2 turns. The bike I just bought was doing that when I checked it at sellers. When I pulled the carbs and looked , it was all the way in. Haven't run it yet , still all over the garage. other wise it sounds like an air leak.

Got the bike back together. Posting pictures with an iPad are a little challenging, working on some others.

So I have to turn it fully in and then 2 1/2 turn back out? With 1 turn being 180 degrees rotation?
