Hi i just wondered if anyone could help me wiv a problem i`m having with my tzr125 the revs are sticking and when the choke is on it idles fine for a few moments then will rise to near 6/7000 rpm. But wen i knock the choke off it will cut out.

It is also under weight ie. click it into first go to set off. it needs a great amount of revs to do so and seems to not want to go over 8000 rpm but clutch dipped wil rev to the top.

I`ve stripped and clean the carb jets no ovaling etc new plug new throttle cable and air filter not yet checked the reeds. plus the ypvs is not driven by the pully system etc how is it possible for me to manually open and close this at will ?

thank you for taking the time to read my post if you could help let me know

You said it rises to 6-7000rpm. Does it do that itself?
