No oil in lines of my T500

I have no oil flow in the right side lines of my T500. The left side seems to be flowing fine. I checked the banjo bolts and washers. They seem to be in good shape.
When the engine is running, I can see small beads of oil dancing back and forth in the lines. The oil runs out of the pump and into the part where the line split in two. It seems that the left side of the "Y" has more suction, and draws the oil from the right side. Once the air reaches the left side it goes up and into the engine, and the 2 lines have no oil.
My friend said when he owned an RD 80, he poured in the right amount of 2 cycle right into a full tank of gas, and disconnected the oil pump. Sounds sketchy. I'd appreciate any help.

Thanks

Sounds like a bad check valve on the banjo. You should be able to blow air through it from the pump side but not from the engine side (do not use high pressure compressed air).
The oil system on the suzukis twins and tripples are different from the yamahas so unless you modify the crank.

Sounds like elbert is right. If the check valve is not working right the pressure from the engine will blow the oil back to the pump and cause empty lines. Most Suzuki 2 stroke engines use the CCI oil to lubricate the crank bearing. Different engines have different set ups. My T350 has the two outside bearings supplied from the CCI pump with the center bearing getting oil from the transmission supply. Yamaha's don't do it the same way so don't try to compare the two engines when you change oiling schemes. I just had a lot of problems with oil lines and it can be frustrating. Hang in there and Good luck.
