For sale is a 14mm bing, a matching square-port intake, and a metal mesh air filter. Was on my k-star until recently, blasting away to the high 40s. Only issue to be aware of is that one of the top screws is stripped, but this doesn't seem to cause any issues, as the other is secure. Complete with bendy throttle cable guide, rubber throttle cable guide boot and all that good stuff. Has a little rubber o-ring in between the intake and carb, too.
No jets. Add your own, cut a gasket, bolt it down, and blast.
