ZRX Gear change

I have noticed a deterioration in gear changes on the Rex, over the past year.
It makes no difference whether I have old or new oil in.

Shifting up is still ok, but shifting down requires more effort. I'm hoping it isn't a bent fork.
Anyone else have / had this?

Bill.

Sorted!

I took apart the gear shift linkage and removed the left footpeg.
Lots of oxidation.









Cleaned it up with fine emery paper, added some grease, and reassembled.

It also pays to clean up any chain grease where the shift shaft goes in to the engine.



Shifts smooth now.

Kewl! Thanks for letting us know
