stiff throttle

my throttle is too stiff on my typhoon
its got a 21mm carb..
is there a specific cable to buy for a 21mm and where could i get one?
or any way to make it smoother coz i have to throttle like a wanker and whe its wet its propa hard to ride..
any help aprecciated

aint got your undertray on? lol

the splitter is right behind the front wheel and when it rains water sprays onto it.
put a cover over it or get a undertray

i got my belly panel on

jamel its the actual throttle
take it off the bars and lube up the underside
that worked for me
an ive lost my fone btw

just ordered some 5.0s and a new piston ring n gaskets

it has got pm mallosi 5g in there allready mate but they do seem to wear down quick on that bike
