If I'm not real hard on the throttle I can make to work and back 3 times on a small china tank, which is about 1.75L, If all out , only two trips, will a puddle left in the tank.
15km each way. Also depends if I'm running a good oil too, Amsoil lasts longer imo.
Clutch gear oil I started with some generic motorcycle oil cause I was broke, Tried some Quaker state gear oil, little too thick, was nice feeling, but too thick when cool.
So i picked up some amsoil 10w30 and that seemed to be pretty good. Just curious what others were using/preformed well.
I fill with about 250-275cc, until it starts to flow out of the plug hole with the engine level.
