    Those cone filter do not work right out of the box with these three wheelers you have to jet your carb accordingly. To run correctly with stock jetting you have to have a filter like an uni or the original filter with the stock box to run correctly. This is most likely why your bike is not running right.

    You might be strong as an ox, but without a cart you are just a big dumb animal.

    It ended up being a wire grounding out on the engine because the shielding was chewed up. Poked around with the multimeter and got it all sorted out. Does anyone know what size the stock jet sizing is? I don't see it marked anywhere. Are Keihin jets universal? Like any Keihin jet will fit? I'm planning on buying the next two jet sizes and trying those. Thanks!!
