Sorry bit long winded...................
Exasperated, 500 AVL I have completely stripped, checked over and rebuilt the engine , it had a hone and new piston as some damage was evident and I fitted a crankcase gasket as it was missing and stuck together with goo. I have also removed the entire EURO 4 system (including catch can), opened up the cast stub by the engine number and run a breather pipe along the chain guard. The original oil tank breather now runs from the top of the oil tank and is plugged into the stub on the air filter box (still have CV carb with air filter) as looks tidy and follows original logic.
Very careful about oil level and kept low on dip stick
So finally all ready and started without issue (sounds good) had a short shake down ride round village, all seemed ok and checked oil level when I got back, needed another 150ml to bring back to low on dip stick . The back brake was binding so stripped the wheel and fitted new shoes (old ones were a right mess!) . Oil tight at this point.
Today took it out today for a back brake test and adjust and stopped after a couple of miles to check the brake was ok and not too tight. To my horror there was oil running off everything around the back of the gearbox, swinging arm and the plastic mudguard section, made a nice pool of fresh oil and a right mess of my bike!! . Checked the oil level and is just on bottom of dip stick.
Too add insult to injury ran out of petrol as forgot I had only stuck a few litres in for a test start and had to push it last mile (near death experience in the sun!)
Just been cleaning it up and the only logical place the oil has come from is out of the oil tank via the breather and into the air box, filling it to a certain point until the level coincides with a hole that allows the oil to drip onto the plastic mudguard section and the rear of the gearbox, inside of filter box is covered in new oil) . I could be wrong but stripped it all and is very oily in that region.
So, what can cause the oil tank to over pressurise as it just has to be the fault, it did it before I stripped it and seems to be still doing it, maybe I put too much oil in it but didn't go over half way up the dip stick but was carful not to.
I feel like I am missing something here and any thoughts would be appreciated!
TIA
