    (I posted this yesterday on the tuning center but got no replys, so guess I'll try my luck here)

    So I need to open up my Aerox's engine to swap crank bearings and seals since they have a big play already, and the crank itself too, since it is actually bent. You can see the variator wobbling when the engine's rotating.

    Anyway, the thing is, even tho I intend to buy a 70cc sports cylinder kit in the next few months, I'm short on money. So I'd like to know what's the cheapest uprated crank safe enough to run a, lets say, stage6 streetrace, which is the kit I intend to purchase in the future (might change my mind, but for now let's assume it's this)

    Also, what variator would be best? I'm trying to rule out Polinis since they're really expensive, so my best options would be the malossi multivar and the stage6 sportpro I believe?

    Thanks in advance :)

    S6 HPC all day. Not the cheapest but its got the highest rpm rating for the money so youll have a bit more choice when it comes to kits and they nearly never go wrong which can only be good:)

    That's the one I was thinking about, tho it's a bit expensive, that being why I asked here. Thanks :)

    And the variator, S6 sportPRO? Or is there anything better in a similar price range?

    That or the 6 roller polini most probably. Theres no major difference between any of them really though.. Tbh if youre working to a budget itd probs pay better to get something even cheaper like the motoforce and spend the rest of a bunch of rollers lol
