RXL Clutch work

Looking for maximum acceleration and trail performance. I currently have a pretty stock setup with a slightly stiffer spring. I just "discovered" ebay and a lot of cheap parts on there. So i am looking for a good weight/spring combo for the primary, and a good spring/helix combo for the secondary.
Anybody have any specific suggestions? the sled is geared down 1 tooth on the top gear.

things to consider: what is the recommended rpm at full shift for your sled, and where are you now in relation to that number? what components are in the clutches now, weights, spring colors, helix, etc? how well is the upshift and backshift on the secondary? engagement rpm? stock vs current gearing?, how adept at clutching and testing are you? and lastly, what are you willing to give up, performance wise, to achieve your goals?

well lets just say this. I don't want to buy fifteen different clutch setups while going through the process of finding the right one. I have 55 gram weights, and I don't know what spring is in there. it engages around 4500 but doesn't seem to have much acceleration as it should. Secondary is completely stock. I'm looking for a suggestion on a specific spring or weights I should buy that somebody has found worked well on this sled before, just so I can buy it once and be done. I'm not looking to tune this thing to perfection, just get a little more out of it.

thinking of getting this Hot Seat Steel Primary Clutch Spring 120-310 Polaris : eBay Motors (item 230351827422 end time May-21-10 09:56:55 PDT) or this Hot Seat Steel Primary Clutch Spring 130-300 Polaris : eBay Motors (item 230351829450 end time May-21-10 10:05:05 PDT) . for better low end and mid range which one would be better, even though they are very similiar?

The 130/300 will start harder and finish lower,
120/310 will start softer finish harder and have faster backshift.

Ok say i get the 130/300, should i get slightly heavier weights? I have 53g weights now, and it has a sharp engagement even though it's at a low rpm. as in the clutch snaps in quick. I read to make it smoother get slightly heavier weights, and anytime you get a stiffer spring to increase the weight? is that correct?

any recommendations on weights? say 58 or 60g?

Yep, go with 55 g weights. This would lower the engagement rpm by about 300, but the stiffer spring will push it back up to nearly the same as what you have now and would pull harder in the mid range.

Ok thanks for the help. What if you go too heavy on the weights? lose out on bottom end a lot?

Edit: Can someone explain the difference in weights... some have a bushing, some don't. all the cheaper ones on ebay that I find don't have a bushing. The weights currently on my sled appear to come with a bushing on the chart.

does that mean i would then need to buy the bushings seperately for the new weights? or swap my old ones in?

Without bushings means that the holes are smaller to fit the bolt and will wear faster.
Or, some you have to buy the bushing separately.

any difference in the shapes of the weights? as i look around at 55 or 56 gram weights, there seems to be some different styles to the tips.

More weight in the tip will engage sooner and finish sooner, tapered tip will hold a little longer and rev higher.
Depends on if you want top end or mid range.

anybody know a place where you can find cheaper weights? I am having a hard time finding anything under 15 bucks for just one of the little guys. Seems a little steep. Ebay isn't much better and the selection is much worse...

That seems to be the going price anywhere.

Ok. one more question regarding the bushings. I just found these on ebay SNOWMOBILE CLUTCH WEIGHTS 04 WITHOUT BUSHINGS 5630229 on eBay.ca (item 260506870268 end time 13-May-10 19:03:27 EDT) they are unbushed, from earlier polaris models (1970-1995). Would these require a bushing to install on the clutch, or are they the kind with a smaller diameter hole for the pin?
