Gear slips beetwen 3rd and 4th whith full throttle

[KTy]

I have this little annoying problem...

When I drive in 3rd or in 4th gear, if I open full throtle, then it as a tendency to slip repectively in 2nd and 3rd gear...

It never happens in 1st and 2nd gear, sometimes in 3rd gear, and quite often in 4th gear.

The solution to prevent it is to handle firmly the handle-bar gear selector...

All the component have been independently checked (1st, 2nd and gear selector) and have less than 500km (for the 3rd and zirri 4th)...

When I rebuilt it, I'm affraid I could have let too much play...

Any advice ?

CHeers,

Frag doch z.B. mal den Gerhard - der hat mal anschaulich erklärt, wie, wo und warum man beim Einsatz des Zirri-4-Gang ausdistanzieren muss.
