Give me the good, the bad, and the dirty about clutch slugs.

I know what they do, Mostly... I mean I know the science behind more centrifugal force, bla bla..

What I'm looking for is how much difference will I notice in engagement RPM ? Lets assume stock is around 2000 rpm, will the slugs drop it to 1800 ?

What are the negative effects?

Can they cause any problems ?

Has anyone installed them and then thought " Crap .... Wish I had not done that" ?

I Want lower engagement for better crawling ability in tight technical trails. I don't like that "Clutch riding " feeling I get now.

I have 1.5mm of shims and a purple spring but I want WAY lower starting speed. I want to crawl at 1mph without burning the clutch. I had it with my 2009 grizzly but my 2016 won't come close to crawling like my old machine. It has WAY more from 1/4 all the way to Wide open. It makes my fathers 2012 700 LE feel like a 550 compared to it, but it wont crawl like his .

Im interested too.

I put them in both my Viking and wolverine sxs's.
Lowered the point where you can feel the wet clutch is fully engaged. I put them in both machines not as a performance mod but as a wet clutch wear preventative. They'll keep you from burning up the shoes on the wet clutch under heavy loads (big tires, crawling, plowing snow)
I had 28" tires on my Viking and after the slugs it felt like it powered up and spun them quicker/easier.
I'll be putting them in my grizzly to help with plowing snow this winter.
I feel like if nothing else they're cheap insurance against a burnt wet clutch.

No negatives at. Much improved wet clutch life. I used to get 200-250 km on wet clutch with 843 cc
Last time I checked 800 kms and still looked like new.
The rhino guys developed them when they stared to supercharge the Rhinos. They couldn't get more than a week on boost


As far as lower engagement RPM ? If you didn't know you had changed wet slugs, not that noticeable as far I'm concerned. Engagement might drop a little.
Sound like you should get the machined JBS sheave to lower your ratio. Run mine with 18 gram weights. the 14s they supplied reved too much trail riding and took too long to shift out


If you have multiple wet clutch failures (meaning you wear off all the clutch lining0 you can pretty much guarantee that your screen for your oil pump pick up tube will almost be completely blocked off(ask me how I know) only way to clean would be to split cases
Best $50 I spent on my bike

Crap, you guys just made me spend another $50.. haha

Did you ever get these tings installed, how are you liking them?

He posted his results in several threads. He loves them, he can crawl easily now. Breath on the throttle and it goes. Wheelies without problem. Anything I missed @Madkawi750

From the man himself.....

Update...

I put the clutch slugs in..
WOW!!!
What a huge difference.
When the machine is cold and idling higher it’s a bit sticky to put in gear and it almost creeps a bit. After 30 seconds or so my idle is a tad lower and no creep or shifting stickiness.
Throttle response is INSTANT.. like just breathe on the fun lever and the machine moves.
The grizzly stands up off the line every time I smash the throttle, but can creep away like a snail if it want to.
I have not woods trail tested yet. Just back yard tests.

It wasn’t that hard to install... the gasket surface cleaning was the biggest pain in the butt.
Also. You’ll need a 27mm or 1 1/16” deep socket to remove the wet clutch nut. REVERSE threads, don’t forget,
Hunterworks sells the new nut with the slugs and gasket kit.. I don’t see why it’s needed. It has a punch tab to stop it from backing off,,, but since I had the new nut I used it.

Thanks! I may have to put these one the short list.

Still lovin the wet clutch slugs. The clutch riding feeling is almost non existent.
I also installed 1mm shim with my Hunterworks machined sheave. I’m now at 2.9:1 or better.
I had spline left but I’m a tad worried about cover rub from the belt.
I have 3.7mm of belt sticking out of the secondary.
I also installed 16gram Slick weights today.
The fun factor is back.
I was spinning on ice today and punched it just to see how fast it would spin up. Speedo read 122km/h at rev limiter. I do NOT have to power to push the machine this fast.. but it’s good to see the sheave brought it from 96kmh to 122.. that huge gains.
Now just need more power.. haha

Awsome you finally achieved the results you desires. Now go out and drive the crap out of her!:wink2:

Hey madkawi, did you put the slugs in yourself? If so , was it easy? And, what are slick weights? I have a 2017 grizzly 700 and in the slowly modifying stage. Clutch work is next for me. Probably going to go with Coop. But will do slugs after reading these threads.

 

[Madkawi750]

Did the clutch slugs my self.
It wasn’t too hard.
Worst part was breaking the engine cover free from the gasket for the wet clutch. It was really stuck. 2nd worst part was cleaning the surfaces for the new gasket. Not hard, just annoying.
The slug part was easy. I watched a couple videos on YouTube a couple times each to be sure I got it right.
I was scared, because it’s an engine casing break open.. but really, it was a very straight forward process.
You will need to drain your oil, so remember to buy new oil and filter. You could tip your machine up an a 30degree angle and the oil won’t leak out.. could save a few bucks if that interests you.

Slick Weights are the new style weights Hunterworks has come out with. They are made from some crazy new super slick material. Very low friction and greaseless. I prefer greaseless for ease of cleaning and tuning.
After installing the new weights and machined sheave (greaseless), my clutch is way quieter than with the stock greased setup.

Thanks Mad . Clutch work is next on the list for me . My bike only has 110 miles on it. Haven’t had time to ride it much.
