Tomorrow I'll be hitting the shop after a long break. I've only found 2 sources for 57mm air filters: Uni and K&N. Reliable sources say the Uni filters are junk, so I'm pinching pennies for the K&Ns. Hopefully I can get the scoot going tomorrow after I crank down the idle and tinker with the Mikunis. My tuning manual is still on back order. If I can't get it running, then I'll have to drain the gas and wait for my filters.
