GS850GL plea for help - bike won't pull past 5000 rpm

[Reckhard]

Why can't you go all the way to redline? Don't have a first gear?

I don't have sufficiently sized testicles to keep the throttle pinned when the bike is begging for a shift...

I don’t like the consistency of not pulling past 5k…..can you find a safe long downhill and see what happens when it’s lightly loaded under full throttle?
in my opinion, the main jet is doing most of the mixture delivery by 5k…..I’m assuming you got the rubber plugs over the pilot circuit.
I asked before if you had the mechanical advancer setup…..apparently some 82’s had the electronic gizmo ignitor.
