Ahhh...... he’s running the head vent into the top of the oil tank.
I wish i could copy/paste/translate the characters off the photo, but I get the idea.
Look at those wonderful exhaust header head clamps !!

This one seems to be working pretty good for me.Oh man this is fun! I don't use chrome or a google translator add in, got tired of running back and forth to a google translate page I tried the mate add in for firefox, highlight and translate without leaving the page...
which gave me.
"] Ah... he is sticking his head into the top of the fuel tank. : Thumbs up Hahahaha This should solve a lot of problems"
I'm still not so sure I understand how that oil tank slash cooler is going to work, or why it's needed.
Well.... don't nobody faint from shock... but I'm gonna agree with Greg.... but for slightly different reasons.I now understand what he is trying to do. I didn't realize the passage from the pump to the screen is plugged to divert all the flow to the tank. I think trying to pressurize with the blow-bye from the pistons won't work. As pointed out a few posts earlier it will cause oil hemorrhaging problems @MacMcMacmac . A sealed tank would build pressure on it's own. It would need to have all the air bled out. Even if the air is not 100% gone it will eventually build pressure once the air is compressed. The motor will be lacking oil till then. The amount of cooling from the tank will not be worth the problems. Behind the engine is probably the worst place for a cooler. My triple is a dry sump. Even thou it has a tank it also has a remote tube and fin cooler. There are 2 oil pumps, one to take oil from the sump to the tank, low pressure high volume. The other to take oil from the tank to oil the engine, low volume high pressure.
Should have added to that... relieving the pressure won't work because it's the tank pressure that's forcing the oil back to the filter. Relieve that pressure and there's nothing to force the oil back to the filter.Well.... don't nobody faint from shock... but I'm gonna agree with Greg.... but for slightly different reasons.
Let's look at a few things. First, we have a positive displacement (pd) pump. What that means is fluid has to pass through it... it has no choice. Without a means of relieving pressure, a pd pump will eventually build up enough pressure to literally blow itself apart. That's just the way they work.
So.... the pump will deliver oil to the tank no matter what amount of pressure the crankcase vent put's into the tank. Until the pressure gets high enough for the pump to grenade itself, it'll deliver.
The problem is, the blow by from the pistons will continuously add pressure to the tank. As that pressure builds... and it will, it's gonna force the oil back to the filter. From the filter it eventually makes it's way back to the sump.... we have a close loop system with no means of relieving that pressure. So the pressure will continue to build until something gives... and something will give.
Yes, hadn't considered that. That applies to the tank to engine return also. Pressure on the outlet side of the filter (through all the passageways and out to the sump) is going to be the same as the pressure inside the tank because they a linked through the breather outlet. So the net flow to the engine will be zero... both sides have equal pressure.pressure acting on the top of the oil surface will theoretically force more oil into the pump, but it will be counteracted by the pressure in the tank, so net oil pressure and flow ¹increase will be zero.
