I have a 65 Tr6 that has been made into a chopper. The problem is that it keeps pushing oil out the oil breather line. Does anyone know what the fix is? Thanks.

Does the breather hose connect to the oil tank or the engine? If so, where?

The breather hose is connected above the front sprocket.

Right now I have 3 oil lines connected to the motor. Two to the pump and one to the rocker boxes.

Does it go onto a housing that's attached to the top of the primary case housing that's cast as part of the left hand engine case? If so, the engine is a later one than a '65. The housing I'm thinking of angles to the rear and upward at about a 45 degree angle. If it is this type, the breather hose used to run up along the side of the rear fender, and if it is mounted lower it might let more oil blow through.

Let me know: Jim

If you look from the ground up. The hose is attached on underneath side of the housing above the front sprocket. I have looked up the serial number of the motor It is a 65. Someone mentioned it was called wet sumping. Does that help?

If it is "wet sumping" (too much oil getting into the crankcase, usually after it's been sitting), that'll cause the problem as the return side of the oil pump is unable to send all of the oil in the sump back quick enough. Then the oil will either be sucked up into the combution chambers and/or blow out the breather. If the bike sits high in the front, there's a very, very slight chance that there's excess oil collecting in the sump, but I'm pretty sure that the rounded cases would let it get down to the pickup. The most common cause of "wet sumping" is oil draining down past the pump because of wear or a bit of dirt under the ball in the pump's feed side. If the bike doesn't blow the oil after it's been run for a while, drain the sump when you come back from a ride and measure the oil you get; then ride it again and let it sit for a day or so and drain the sump again. That should tell you if there's a problem with the oil leaking down (after you compare the volumes, of course). If it is a leakdown, the pump has to be pulled and serviced. Sometimes a tap with a hammer will reseat the ball, if the pump's body is made of brass, but you'd probably be better going with a Morgo type pump. Like I said in the beginning, this is the most common cause of excess oil blowing out, but there are others; if you haven't got a good manual, you really should get one. I found most of my info from the Clymer one as the Haynes didn't seem to have anything on the problem, which I found strange. Some of what I told you came from dealers "way back when" and you won't find it in a manual. I hope this helps solve your problem, or at least gets you on the right track. One very silly question: the oil lines are connected correctly, aren't they? Can you see oil returning to the tank with the engine running? I really hated to ask that question, but....

Good Luck: Jim

The bike was a gift from my Uncle. He had it in his back yard for close to ten years. He informed me. He would start the bike maybe once week or less.
I have completely redone this bike except for motor and trans. The reason I have not done the motor is it still has a lot of get up and go and it shifts well. Yes I did the small things rebuild the carb and change oil seals. Compression was good and it runs well. I have only put about 60 miles on the bike since putting it back together. Short trips about 5 miles. I will keep an eye on how much oil is being blown out. I think I will try and take it for a long ride. If that doesn’t fix the problem I will put in the new pump.
Thank you for you time Robert
P.S. the oil lines are correctly connected. I was so paranoid that I would hook them up backwards I had a few friends come over and make sure i did it right.
