the oil is in the hole under the brake cable holder. basically onto the spring. and its oil for my yamaha zuma's transmission, so its thick, also, the spring is really tight now so i dont think that a little slippage is an issue, my problem was originally that i could rev it and not move the bike. i can deal with a little slippage until the oil burns off. and i didnt get to try it, but i have work soon so im going to test it before i leave and if it works just take it to work.
