Carb identification

[Chainlube]

sorry I didn't specify. I am in the UK where parts are much more scarce and these bikes have much less of a following. those predator 212 engines are also not sold here so we don't have parts for those either. maybe I will just put on an old nt carb until I can find good jets that are the right size

You need a 68 anyway, Pull out the jet you have and measure it and compare it to ones on M/C repair shop sites and ebay and such. You'll find the right jet. Or, solder it up and redrill it out. It probably be easier to find a set of precision drill bits than a jet.
