Let me pick your brain

Whats up guys I was just watching TV and had a thought. Some of us say a boost bottle helps throttle response and some say it don't work at all. Now what if you use the same set up but instead of the boost bottle you would use a propane bottle. So after the motor is started on gas you could interduce a small flow of propane gas to the mix using a torch valve. What do you guys think... could it be to much for the motors?

If using propane instead of 2-stroke gas, where is the oil going to come from?

You would still use gas and oil. The propane would be connected to the intake ...between the carb and the motor..... only when riding would you interduce the propane to the intake adding propane to the gas and oil mix. It might help with pulling some of those hills the motor might need some help with. i wouldn't run it to long with the propane...... Kinda like a shot of nos with out the hi price set up.
Propane is like 110 octane or 115 octane. Might give a little boost?

in that case, you're adding extra fuel...where's the extra oxygen going to come from?

I went and did some research on google and this is what I found it has the same concept as I have in mind just introducing the propane after the carb.

it seems like the problem with the system you linked was still getting more oxygen into the mix unless i read it wrong.

Yes he was trying to use the propane before the carb..... I think you need to use it after the carb in the intake as a boost.
