Hey all,

In the interest of having my 79K run well and not foul plugs or burn valves over years of use, I'm switching back to the factory airbox after giving pods a shot. They work decently well, but have a few problems--- throttle response is a little sluggish when I flick the throttle (even though carbs are clean as a whistle, rebuilt, and the accel pump is squirting fine) and I don't think it's going past 6-7k rpm (I'm uncertain, though, because the tach needle is warped and sticks so I can't tell).

As everyone says Honda jetted the carbs lean from the factory due to EPA restrictions, I want to step up my jets a little. For the needle jet I was gonna go from the factory 102 to a 105 and for the primary I was gonna go up to a 75 from the stock 68. For those of you familiar with the CV carbs, does that sound like a good change for both? Is 68 ---> 75 too big a leap?

for the record, I have stock 4-4 exhaust and no changes to stock needle clip position.
