What jet to go with on my lt500.

[ltflyby89]

I have an 89 zilla that I bought a 530 big bore kit for. I was just wondering what jets would go good on my setup. I have the 530 kit with a 41.5mm pwk with an fmf gold series pipe and an fmf fatty series silencer. Also an airbox eliminator kit with a K&N air filter. Any info is more than I can come up with. Thanks.

Did the carb come with the 530 kit? Who sells a big bore kit for the zilla? I would think the people that make the kit would have jetting spec's.

a banshee thats 3mm over bore is around 530 is it just bored over sized or is there a new thicker sleeve installed ? anyways i would probably start with a 180 main and chec k your plug and go from there
