Can't past 6500/7000 in 6 gear

[niko]

I found the problem!
I do not have enough air coming despites my pod filters!
when I take them off there isn't a big difference except I havn't this problem to 110km / h, I ride without a problem (I tried 140)!

I do not think too rich yet, maybe it is a problem of turbulent air behind the filters at a certain speed.

I will try put the pod away the carb with a hose

Interesting. Ram air time?

Maybe a carb piston not lifting right because of leaky diagram... take out and shine a light on it while looking on otherside for light.

Theses seem to help, they lift piston a little higher on idle

The pods are masking the diaphragm inlet. that's why I kept the inlet pipes and put the pods on those (it also supports the carbs too)
