wriggz

I have just bought a sr125 as a commuter too and from work. However on the day ov purchase i went out for a little ride, to check everything is as it should be. Apart from a false neutral everything appeared to be running smoothly, untill i got on to my street that is. My street is on a hill, when riding down (approaching a centered speed hump) doing about 30 in 3rd, i pulled in the clutch and proceeded to brake, i then knocked it down into 1st and waited for a car to pass, as i let the clutch out again, there was no drive whatsoever?? and a faint burning smell. Now she wont start, its probabley the clutch but as i am a novice am not to sure?? Any help is appreciated, need to know the actuall problem and what to do to resolve this issue. Thanks again
