110cc pocket bike it has two place to put oil in what kind of oil?

I think you will find on the 110 that you only put oil in the right hand case, the left one is where the electrics are. When draining oil. only undo the bolt on the right hand side under the motor (looking from the top) that is closest to the filler hole. DO NOT undo the other one on the left, this is for the cam chain tensioner. Warm bike up for a few minutes to allow the oil to drain easier and rock the bike front to back to make sure you have got it all out. Replace your sump plug and fill with semi-synthetic 10w40 oil. I like to change the oil about every 50 hours. You will get about 6 oil changes from a 4 litre pack (600-700 mls per change), so it's not that expensive. Hope this helps. Greg, Sydney.
