9R clutching
- Thread starter mk818
- Start date
Another update, after completing break in:
I believe the stock clutching is designed around maximizing quick build of track speed around this fast revving engine. So far it's pretty darn good for stock.
Even though the supplied 72g weights are stated to be "high elevation clutching, 7,000-9,000 feet," I believe the 14-72 weights to be correct for 9-10k ft, where I'm seeing regular 8350-8450 rpms. Haven't ridden above 10k ft yet, so I can't guess what the engine will pull in that range.
So first hypothesis: the chart in the manual is skewed 2g light across the board for the polaris 14-XX weights.

RPM’s were not bouncing during the pull. This is RPM range throughout out the day. So for instance, at the 6,000’-7,000’ range with 72’s I am seeing the higher 8600rpm and at 8,000 - 8,900’ seeing 8400RPM.
Still in break in mode.
yesterday mine was hitting 8400-8500 at 8500ft. 2 feet of fresh, snow (not blower), on top of thick dense "sierra cement"
100% stock clutching.
aligned my clutches last night, added proper float to the secondary. it had 0 from the factory

What engagement rpm are you all seeing? I really like the low rpm engagement on my current Ibexx clutched 850, it's around 3400-3600, stock was 4000.

If you can get even lower rpm, your boner will grow 1” per 100rpm. It’s that exciting!

Who offers adjustable weights for the P22? Dealer wants $147 CAD for stock 14-74 weights.
That sounds about right. They aren't cheap. I paid $252 USD for the speedwerx adjustables. Anything adjustable is well over $200 USD.

why not just change the primary spring to a lower finish rate to lower the rpm.
You obviously haven't been following the forum expert's posts. I know nothing about clutching and Rusty is unwilling to help without major financial compensation. I don't know how to change springs but I do know how to change weights. ?
where are you seeing stock 14-74 weights?
i know the manual shows them and a part number, but when i look for that part number on Polaris parts page, nothing comes up ??

What is the stock 9R helix?

Chilly is correct. My price for working on his Polaris and knowledge sharing is not cheap. Especially when you have to wave magic wands at dimensionally out of tolerance (new) junk like this one.
Guess i could have looked at my owners manual

Looking for a 155, 2.75, 9R RMK. Riding 6-7000k is my sweet spot getting over 8k at times. Would you get the high elevation clutching?
I am running the stock high elevation helix (56/42) with 78's and 150-310 spring as we typically ride under 6k. I was pulling 8400 at 6000'-6200'.

I am riding a 165 9R pro with high altitude kit. Riding from 5000-6000ft and had to change to the 76 gram weights to get the RPM's down to around 8350. Runs good with that combination at that elevation.
