I went for a ride today and need to ask if you ran your scooter hard is it possible to leak a little oil around the egr area? My scooter is two weeks old and I put in a new vairator & rollers , a racing clutch yellow 1500 spring perf coil , cdi and iridium plug , synthetic oil and gear oil , gps had me rolling at 64.9 mph , I wiped everything down went on a mellow ride and no more oil ? Thanks

Synthetic oil is very fine and any little inperfection on any gasket or mateing surface it will leak. Are you sure it was leaking by the EGR and NOT around the PAIR system? The EGR is a Valve welded to a piece of pipe on your EXHAUST pipe.
Here is an EGR and PAIR system:

It was underneath the pair system on the underside bolt heads , now im kind of wondering if I might have added to much oil ,as when I replaced the head and had it all apart there was some oil under the scooter , and when I put it all together added about 6 oz & I dont think I lost hardly much at all , I saw on YouTube to check oil level all you do is place dipstick in hole? Or should I wipe it and thread it all the way in to check it? Thanks:)

Checking the oil level you can do it either way, IF you do not screw it in the oil level should cover HALF the xxxx's IF you screw it in ALL the way the oil should cover all the xxxx's.

Also it is pretty hard to overfill the crankcase with oil UNLESS you have the SCOOT at an downward angle that the oil will start to fill from the FRONT of the motor case so that when you finally get it level it is WAY overfilled. But if you have it level then if you fill it almost to the top of the fill tube it is really only about 1oz more and will not make a difference. On the other side of the dark side if you have it angled back then you will be low on oil when the motor is level.

The leaking I think maybe the VALVE cover gasket is not sealing around the valve cover and or the rubber gasket is not in its groove around the valve cover or part of it is pinched.

That's what I was thinking also. A leaking valve cover. A little tightening of the bolts should fix the problem.

Not sure if the 150cc's method of checking is the same as the 50cc's, but if so then that information is incorrect.

With 750ml in the tank, the crosshatch on the dip stick should read full. screwed in it should read over full.

You may need to change the gasket for the valve cover or tighten the screws to it if loose. Too much oil will effect performance and blow out of the tube connected to the valve cover.

They are all the sameo sameo 750ml for the 150s as well no diff. Like I said even if you fill it all the way to rim that is about 1oz of oil IF you have it on level ground. Only way to overfill a scoot with oil is to have the front end down at an angle so the oil is being filled from the front of the motor so in this case YES you will overfill it other than that not a problem with to much oil. You could on the other hand not have enough oil in it IF you have the scoot angled backward in which case the oil fill spout will show full when the majority of the motor case is empty.
Just common sense really, don't have to be a genius, do it with a glass of water tilt it and it will overflow before the glass is filled to the top.

I'm confused... Assuming the bike is level while on the stand, when adding 750ml after draining the oil the dipstick will read at the top of the crosshatch when not screwed in. Screwed in it will read over it. Why would the bike be tilted forward or back? While on the stand if you fill the reservoir to the very top. It WILL overfill and effect performance and or blow out of the vent tube. Common sense should tell you to fill the tank while level.
