i apologize. i obviously mis-read your first few statements. i thought you bought a used clutch. but you actually bought a used maverick.
what machine did you come from? hopping on a can-am if all you have ever ridden is rhinos or hondas seems alot different. on a can-am you have an engagement RPM. the clutch will not engage untill you reach that engagement RPM. on a wet clutch style machine like a honda or a yamaha, as soon as you give it gas it goes. the can-am does not act like this. you have to give it a little gas to make the clutch engage. and when it engages it WILL make a "clunk" noise and almost jerk you to get you going. its just the style clutch that is used on all can-ams.
if the machine is modified, and has a clutch kit in it, it may stall up to an even higher RPM than stock.
your idle is typically 1200-1300. and it takes around 1900-2000 RPM for the clutch to engage before it will start to turn the tires.
