Hello all, I'm considering getting some aftermarket parts for my 1996 gb250 (single carb) and was wondering if anyone had recommendations, does k&n have an air filter that would fit this bike? Is it worth upgrading the carb? The stock carb is a keihin pwk 28 I believe. Has anyone played around with their set up? I'll leave the look stock mostly, but I'd like my engine to be performing as well as it can be.
