Hi All.
Where goes the tube from crankcase camshaft breather?
The oil tank has only a little tube on the top that i think is the venting of the oil tank (or the chain olier).
I cannot see a tube for crankcase breather.
Thank you.

I do not know N15.

On Atlas and Dommie, tube for breather turns down toward oil tank bottom. Tube for vent and chain oiler comes straight out. Perhaps this will help.

Hi Slick,
thank you.
The N15 oil tank has only the bottom oil outward and return and upper a little tube (so thin that you think it cannot be for breather hose).
N15 is different.
Where the camshaft breather goes?.
What need the upper little tube?.
I hope Bill can reply me about.

Piero, on my G15 tank there is a tube going into the inner side of the tank at the top more or less in line with the raised tower with the thin tube, I believe this thin tube on the top of the tower is only a breather tube for the tank. The tube sticking out of the side is for the engine breather.

Hi Dave thank you so much.
Sorry, but where is this tube?
I have only outward, return, plug, and oil tank breather.

6 holes in my G15/N15 tank:

Fill hole with chrome cap at top front
Oil supply at bottom front, screw-in filter with nipple
Oil return at bottom front, nipple just inboard of the supply
drain plug, just behind oil supply
Vent nipple, midway back on the top of the tank. about a 3/4" tower, 1" high with a 1/4" nipple pointed toward the rear of the bike
Crank case vent nipple, just behind the vent nipple in the top side of the tank. sized the same as the fitting on the case

If you do not have the last nipple, run the crank case vent under the fender and exit at the rear of the bike, along side the oil tank vent.
 
There is a G15 oil tank on E-bay USA at the moment with some good photos of the side mounted tube.

I CAN FIT? I THOUGHT TO DRILL AN HOLE AND SCREW THE SAME PIPE ELBOW of the camshaft breather.

Thanks for helping me.
