standard hand throttle on my aerox can not fully open a 21mm carb slide

Hello guys!
Anyone else notice that the standard hand throttle on aerox can not fully open a 21mm carb slide?
No matter how I adjust the cabel.
Do I need to buy an aftermarket throttle grip assembly that can fully open a 21mm or bigger.

 

yeah my tenant had a 21 on his bws, he bought a new cable if i recall, or you could buy one of those repair kits and make your own? (which is what i would do, then you have a repair kit too)

 

du kan prove paa crash.no eller speedoptions.no. kansje biltema selge de kit og? men husker ikkje....
