Lucky---
let me rephrase. When I talk about throttle response, I am talking about throwing the throttle wide open. When I do that, the response is not necessarily sluggish, but compared to my friend's 81c which is running with an airbox it seems slightly slower to shoot up into high RPMs, but doesn't really bog or starve. Lower end is perfectly responsive. It is almost as though my slides are reluctant to rise as readily as those in my buddy's bike, which is probably the vacuum issue from podding everyone warned me about.
In answer to your question about the tach--- the needle moves freely between 1k-5k rpm but is clearly catching on the plastic face of the gauges around 5k, and I can tell that the engine is revving higher even once the needle's stuck at 5k. I am guessing it's hitting 6k or 7k tops.
I am not asking for advice about cleaning my carbs or changing needle position. They're fine other than the usual BS I was warned about with pods... even so it runs pretty okay.

I am saying that I'm going back to a stock airbox setup and that I've heard it's good to increase the jet size a step or so for the primary and secondary mains because of how lean the bikes were jetted from the factory.
Have you or anyone on the forum heard of or tried this?
