my clutch engages at 4500 rpm and i was wondering if a wider belt would fix this problem or would it harm the clutch. Thank you for your feedback.

depending on what sled it is thats probably around normal. if you engage to low you will bog to high you will spin the track.

Talk to some Polaris guys on clutch set up, you never change the belt size, try a new one, but you will posibly need to change your spring, arms, rollers, or pins or a combination

for that sled a good engagement should be around 4000-4500. run the 045 belt. just changing belts wont change the rpm. it should be set up properly with a new belt for proper side clearance, and belt deflection. if you really want to change the engagement, you'll need to have the spider shimmed. this will also affect the side clearance. there' a lot more to it and more components to change that can affect the engagement, but then that's a whole other conversation. if you absolutely want to change the engagement, have a shop check it out and adjust it for you. if you have any other questions, please ask. -Polaris Doc

Well, a belt can change engagement. If a I have an older belt that's been run hard and is narrower the sheaves will take longer to get to it, this will raise the RPM, however it is atmost 100-200 RPM max.

Compare the components you have in the clutch to the stock setup you'll find in the manual.

Triple650Indy...not trying to get into a pissing match here, but lets think about this. actual rpm until it engages the belt when you hit the throttle, sure the rpm will be a few hundred higher with belt wear. however, the cetripetal forces remain constant given a certain combination of weights and spring. the actual rpm, when the moveable sheave starts to move, should not change unless components are changed or if the moveable sheave is shimmed in or out with spacers behind the bolt that will push it in or out, changing the starting position of the weights. erratic engagement could occur with a clutch that has worn components, rusted shafts, or improper button clearance.
proper side clearance will reduce the jolt felt, and will give a smoother engagement. if the side clearance is too much, shimming behind the clutch bolt washer using plastic shims will give you the proper side clearance you need. if shimmed in, the weights will start higher which will effectively lower your engagement. you can also get proper side clearance by shimming the spider in or out, but this requires special tools and complete disassembly of the clutches. let us know how it goes. -Polaris Doc
