Just wondering, took my oilpump cover off today and saw the well full of oil luckily it was blue as my two stroke oil, not as tranny oil... It dried it out, gave it a god clean with degreaser and 5 minutes later noticed the it was starting to come out again where one of the small clear oil lines are going out of the plastic piece under the pump, and also noticed some air in the same small piece of pipe. The other two seems ok, and no air in those hoses.. So the million dollar question is, can I glue the bastard or what can fix this issue? And from where is the air coming in the system - perhaps backwards from the casing... Grrrrrrrrrrrrrrr!
Sounds like one of the lines has cracked where it leaves the adaptor plate.
It cannot really be fixed in situ at that end, I would guess (you can fix a leak / crack at a check valve end, at least sometimes, as it can be completely flushed and cleaned externally).
If the crack is right where it leaves the base, I'd be inclined to get a spare oil line set.
If the crack is a few mm away from the base plate, you may be able to 'sheath' it with a split piece of tight fitting tube + some adhesive. While many don't recommend this, it is a very low pressure system and you do have good visibility.
It is exactly where it leaves the block, as it seems to get "wet" around the edges there... hmm. Maybe there is enough pipe to cut it at the plastic block, then drill the end out, and then stick it in again with some glue around... But where is the air in the pipe comming from? Hmmm. How are the banjos exactly working, Is it a non return valve?
Just make 100% sure it is the plastic "octopus" that has the leak. My pump was leaking for a while and it turned out to be the seal on the activating arm. Very hard to see oil on the surface of the pump but I stuffed some paper towel under the arm and sure enough that's where the oil leak was. Replaced the seal and all was well.
Yes. It's a one way valve. Similar to the SRIS valves.or a common check valve. The air is most likely entering in the same place where it is leaking. Is the air traveling toward the motor or away? Is it a line that feeds the cylinder or a line that feeds the crank?
I was born with nothing and still have most of it left.
Thanks for participating in my problem. I will check again where the oil is coming from, but I am quite certain it is from where the hose is entering the octopus. I gave it all a nice blow of degreaser and the pump still looks dry and it has a ring of oil on the outside of the octopus hose joint.
I will start the bike up tomorrow, and check what way the air bobbles move..... and where the hose is going...
If you completely clean the octopus, and I mean really clean, plastic welder (or plastic welding system) will fix it. It's a two-part epoxy the sticks to nearly every form of plastic. I nice glob over the crack may fix it. The stuff is sold by several different manufacturers, Permatex, etc. I have bought it at Auto Zone, Advance auto and several hardware stores.

If you stroke it more than twice; you're playing with it.
Too many bikes, too much time, ENOUGH SPACE, FINALLY! Never enough money.........
So now tracked down to the joint between the plastic flange under the pump and the pipe, witch is halfway broken off...
Tried to find the glue you suggested, but that is not available in Denmark from loctite
Anybody who knows what material the bottom flange is made off? Is it POM? It seems to be one of the "fat" types of plastics witch is not easy to glue with all types of glue...
Loc-tite is not the only one. Permatex has a version, in the States even tru-value hardware has their own version. I feel sure we could get some to you......

Did some flushing of the oil pipes the other day, the inline check valve was leaking, flushed it again now with carb cleaner and air, very gentle air pressure not to harm the small springs, filled the bastard hang it upside down, no leaks 4 hours... also got the small broken pipe glued to the base, cleaned it, gave it a gentle rub with emery cloth, cleaned it again and glued it.
Loctite 3090 is a new flexible product that can fill up to 5 mm of air, but have some of the similar compounds as normal instant glue.
