Squeaky wheels and revs with no acceleration?

Yeah sounds like a slipping clutch. Clutches generally last a long time if constantly driven how they are meant to...but people sit at traffic lights holding the clutch down while in gear and people also hold cars on hill starts using just the clutch. All of this will completely ruin the clutch. if them reciepts you found just say clutch fork and clutch cable then you have never actually had the clutch changed. The clutch cable goes from the clutch pedal to the fork..the fork then pushes the clutch on and off the flywheel (engages, disengages). Clutches on these can be expensive to replace...take it to a big garage and your looking at about �600+ ...smaller garages or mobile mechanics will be cheaper..but you may have no warranties on it.
