i'm running my oil lines and i can't find anything on how to tie in the one coming from the underside of the primary..in everything i've looked at i can't even find a reference to it..not on diagrams or anything..does it just tee into the return line?? any info would be helpful as fuck..

Under the primary? What year is the engine? Are you talking about the crank case vent?

You have a vent for your oil tank and a crank case vent #8 in the image, both vent to the atmosphere. mine run together at a T then toward the back of the bike under the frame open to the air, my bike is not stock.

ya it is the crankcase breather vent..i just checked my girlfriends tr6 and it has nothing on it..just ends at the tube..is this a decent way to do it..just leave it??

Just my thought but it is a vent tube so I may be wrong but I don't think it has to run to anything. If I did run it to something it would be to T it into the return line to the oil tank but it is so hight up on the case I doubt a lot of oil would make it into it. I am building a 68 Triumph Bonny right now check out the build in the main forum titled first build.

I think just leave it is the way it is suposed to be it is just a vent tube.

remember a vent not only takes air in but also lets air out meaning it is someplace to let the hot air from the hot oil out.

I would try leaving it and see how the bike runs or if it blows oil. If not then good if so T it into the return line to the oil tank and see how that does

Run a line towards the ground so any blow by will drip on the ground and not all over the cases, its hard to clean up there. DO NOT T to oil return line, it is a vent line

it is a vent and should ideally be run UP the rear fender via a "D" shaped hose,ending at the REAR of the fender by the tag... [and on some models, "T"`d into the final drive chain oiler] this should be run UP as to allow for the oil droplets to run back into the chaincase upon shutdown/idleing...you really shouldnt run it down as it WILL produce some oil and you know where that oil is going to endup, right? on the rear tyre! seen it done [ran straight down] a hunnert times with no real apparent bad effects, but it really should be ran up, youll probably have to refill the chaincase not nearly so often.........

dont tie it into the return line for your oil or your oil wont get back to the tank properly and will end up going into the bottom end through the intake cam bushing. i think its in v-twin they make a really cool alum canister with a filter on one side and an inlet on the other. that way it breaths and catches the oil.if nothin else just run it back a little ways an youll know where its gonna mark its spot.
