Slight Stuttering/Power loss 4-5kish Rpms in every gear 1978 Gl1000

Hi All,

New to Goldwings and motorcycles but not to the forum. You guys helped me solve some ignition problems and now the bike is running nicely on all 4. Link to the thread below in case anyone is curious. It also details what I've done to the bike thus far pretty well.
viewtopic.php?f=3&t=40457

So the problem I'm experiencing is that the bike has a hard time accelerating between 4 and 5k rpms but after I get past 5 or 5.5k I have full throttle response and power again. It kind of has a stuttering feel to it when it's going through those Rpms and it makes a kind of stuttering noise that sounds like it's coming from the right side near the valves. I know stuttering isn't the most descriptive word, but it's not a tapping, knocking or clicking noise so I don't really know how to describe it.

It's not super noticeable, but if I'm accelerating quickly through that range there's a definite power loss that kind of comes and goes in little waves that I've been calling stutters.
I haven't adjusted the valve clearances yet because I'm being lazy about buying the new gaskets for the valve covers but I will if that's what we think it is.

Anyone have any ideas?

I believe you need to pull the carb rack and give them a clean.

Sounds like the sliders are not slippery enough. They need to move really easy with no friction.
