Motorized bicycle spark plug flamethrower mod

I'm having the same problem with my customers bt80. It's just slow take off if any take off and feels like it's always slipping. It's says to add oil to it (haven't the slightest idea why since it's cent clutch) people tell me use normal 10w30. Being a motorcycle tech, adding car oil into ur bike is among the most blasphemous thing u can do right next to spitting on your mother and driving a scooter so I decided to go with 2stroke oil instead. It's works alright maybe 12mph out of it but I know it's capable of more. It's gotta be. Average rear sprocket not to big or small. Could be, am I supposed to run it dry? like my intuition is popping a synapse screaming at me to do? Or perhaps gear oil? Or hell why not brake fluid? Or mineral oil? With normal wet clutches the oil lubricates bearings, keeps the engine clean and keeps it cool. Well with this application is not doing any of those things; grease keeps the bearing rolling, the gas keeps it cool, and the oil in the gas keeps it lubricated. I cannot see the point of oil in the clutch

You need to be asking @Gordy these questions since he has had a BT-80 and knows all of the ins and outs of them first hand.
 
As odd as it sounds, it is a wet centrifugal clutch. They tend to slip until they are almost at max rpm so they are designed to have oil so they last longer. You'll find a little plug on the right side engine case. Pull it and fill it with 10w 30 non detergent oil. It takes a very little long time since there is no vent and I is a very small hole. I ended up pulling the bolt out of mine and threading a brass nipple into it so I could put a hose on it and kept it slowly fill up, and I put a vacuum cap on it when I was done.
 
Okay cool thank you, you sound confident so I'm taking your word for it. Now as for the amount; should I just funnel it in the side with the bike upright till it starts to pour out like one would do with a rear differential? Or on its side and a predetermined amount?
 
I was working on a 196cc clone go kart w/ a buddy.

We took off the muffler and it was shooting flames constantly.

Then we put it back on cuz the sheer noise caused us physical pain. Imagine what the neighbors must think.

I flipped the bike on the side and stuck a funnel in the hole and filled it. I just put as much as it would take, stood the bike back up, and let it drip back out the hole until no more came out. I tried filling it like you mentioned, but it doesn't work, so you have to lay it on it's side and let the extra drain out when you stand it back up.
