Honda Hornet 250 throttle adjustment!?!

[Sleepr]

Hello everyone, I have a problem with my 250 hornet. I think my throttle cable needs to be thightened, I am not sure on how to go about it. For some odd reason I have to twist my throttle a 1/4 more to get the bike moving, there is no memory in the cable to this 1/4 mark, after the 1/4 mark the bike behaves as per normal. I dont know what happend, I got off the bike to check the tyre pressures at the gas station, next minute I start it up and the throttle felt weird, and then I realised that I have twish the throttle a lot more just to get the bike moving.

PS: While I am twisting the throttle 1/4 way, the engine revs dont even go up above idle, this suggests me that somehow the throttle cable got stretched? or something wrong with my throttle thingy.

Please help

Went to botany honda today, the mechanic said the throttle return cable is broken, booked it in for next week . Hopefully wont cost me a bomb.
