    ok i'm turning to premix on my ice and was wondering what the best oil ratio was
    i'm running a standard cylinder with a zx exhaust and 21mm delorto carb with no filter (it fell off)
    so what ratio do you wreckon would be good and howmuch would be good to upjet?
    currently running a 90jet (sounds high but bike ran fine and did 50 allday long) ive been sujested to run 50:1 and im thinking a 92 mayby 95 mane jet?

    Why on earth would you want to run it on pre-mix, as for running it with no filter get ready for an engine rebuild. :confused:cratch:

    50:1 is fine all day long, your oil pump uses half this

    gilly whats wrong with pre mix lol? im goin to be running it on premix as ill be rebuilding the engine soon with some tuning parts and i dont want to rely on the pump, also the oil tank is in the way.
    i will be replacing the filter
    thanks minor, will i need to upjet it or will the jet i already have be ok?

    Now't wrong with it mate, we run it all the time on the race bikes but it can be a pain in the arse on a road bike having to mix it on the forecourt etc....it will also have to be a high end engine to overcome the pump, if the tanks in the way fare do...ps: in the way of what. As for the jetting it depends on your engine specification .regards liam.

    the tank is mounted in the frame on the ice and i want to run the loom and other cables through the frame which a cant with the oil tank in.
    i dont really trust the oil tanks as the 1st 70kit i had seize was apparantly because it wasnt getting enough oil from the pump
