DO NOT RUN 87 IN YOUR BIKE, run premium or better 91 or above, and for the drain bolt just look on motosport or egay

2 stroke engines do quite well on 32 to 1, fuel to oil ratio. Make sure to use a quality 2 stroke oil. Not automotive oil.

Two stroke transmissions often use regular automotive motor oil. 10-30 is a good choice.

The drain plug is metric. Likely a 10 or 12mm thread with a 1.5 thread pitch. Sometimes, auto parts stores have replacement drain plugs that will fit. (sometimes in the "help" section) Make sure to use a gasket.

Good luck.

A dealer should have one in stock. Who cares about the price of such a small part, it's kind of important. If no luck there try http://www.mrcycles.com/
