[ozybiri]

hello guys, i had a problem at the third gear, there's something slip arround (probably the clutch) when im hold the throttle, i'm not sure if the clutch slipped or something...
recently im using stock clutch plate... i hope you guys could give me some advice
one more, which primary gear is fit for parmakit blok 130cc? is it 24/61 or 27/69? and what the advantage if i use them? 
thank you...

Hi Ozy, I think you need to move this to the technical section.
