I used to run motul 710 @ 40:1 in the gasser (only cause it smells like bubble gum
) but now run amsoil dominator @50:1 and after 2 days of riding through the bush of the central north island (NZ of course
) I have enough spooge to wipe off the a garden variety nose tissue
. the bike does run a little rich up there too due to the altitude. I just did a new piston ( 250 hrs) and the jug and piston were pristine and there was a nice layer of oil over every surface of the inside
