Hi. Congratulations on your videos. I need to raise my Polaris RZR 800S by 200 RPM to bring it up to factory specs of 1200 RPM. I understand that I need to take off some weight. Let's say 4g. And it occurs to me that instead of changing the weight of the arm, I could drill a hole in the area you indicate in the video. Maybe I'm just being silly or crazy. I don't know. What do you think?
Yes I would consider a steeper helix
Hey so i have a 2024 can am defender lonestar come with 30 inch stock i put 32 inch tire with dalton clutch kit weight in primary like they said and spring in secondary with helix but now i just put 20%gear reduction with 35 inch tire but i have to much rpm i didnt touch the clutch again should i put back the helix to stock well put the primary and seconday to factory or play with some weight
Yes tip is toe
If the base is “heel” the tip would probably “toe” would it not?
How are the 2024s performing? Has this issue been resolved? Any info is appreciated!
The 24s have been doing great, yes all of those issues have been resolved.
For deep snow run ability the boondocker tunnel exiting exhaust and proper intake modifications are a must
Need some updated vids tech talk
Can we get some more clutching videos! This info is awesome!
Any testing with p85 looking at clutch kit and considering going that route I will definitely have one with as a back up.
We have done alot of testing with both p85 and p22. For many reasons we much prefer the p22 and have had very few failures on boost, now with the updated billet spider the p22 is even more reliable.
Great video, please do more.
I'm late to the party but this is great information that is communicated very nicely. Not may people understand this information. Well done!
Rookie question! Stock xp 1000 wot shift rpm is 8.000rpm, i want to get that up to 8.500rpm for high performance trail riding for that extra punch. To achieve that should i just adjust clutch weights? Or should i look into ECU map? Recomendations are welcome, Thank you
I wonder if you know why the 2023 9R's and even boosts are blowing up clutches and they are eating spark plugs often. I believe there are harmonic issue going on; likely in the clutch. Have you found this and if so have you found a solution.
Eric, Being that this video is a couple years old now wanting to know what your finding have been now with the Boost and the 9r. I currently have 155 khaos boost 2.75 track QD2 and 146 khaos 9r 2.6 track QD1. I am looking to change both unit to the TKI kit. However I am wanting to change gearing and not just run the standard ratio if I am spending the money to change to the TKI kit. Any thought?
Very nice information! What is the formula to calculate the final ratio when I already know my belt drive ratio? 2.63 with 8 tooth 3" pitch
The industry chose to commonize that variable to create a relatable final value that transcends brand and model. Otherwise the relevant consideration wouldn't be final drive it would be gear ratio. Which in most cases is all that really matters. I think it's nonsense also and believe that individual final drive should be considerate of individual driver configurations... don't blame the messenger:-)...
Why would you give a lower theoretical final drive if you haven’t changed the drivers. If you have 22/50 (2.27) QD2 and then run a 29/69 (2.38), clearly the 29/69 is lower as they are both using the same sized drivers. If a skidoo is 21/53, (2.52), with 6 tooth 3.5” pitch drivers, why would you change the final ratio without actually making a driver change. That’s what they come with. I feel like the info provide wasn’t very clear.
You are absolutely correct, that was something I clarified in comments earlier. That information was essentially Incorrect or at least unclear with respect to the SkiDoo. I apologize for that.
@@TheVOHK same as the Polaris gear down. There is no need to factor in drivers as your not make an actual driver change. The 22/50 QD2 is a higher gear ratio then the Kurt’s 29/69.
Maybe it would be easier if you gave me a call so I can explain. It boils down to all manufacturers commonizing the final variable of final drive and that is why you make the driver correction. It is an effort to create data that will transcend models and manufacturers and still offer a relative expression of final drive. Otherwise we would just be talking gear ratio. Happy to chat with you sometime feel free to give me a call at the shop. 970-724-9655
Where you're going wrong is at the time that we were testing and that I made that video as indicated in the above comment the Kurt's gear down kit was a 32 67 ... that was all they sold and that was all that was available at the time. They have sent altered their gear down kit and it is indeed now a gear down kit but like I said at the time the video was made the Kurt's gear down kit was actually a gear up kit. The facts don't lie.
Great video….even tho I’m a Cat guy lol….just fyi the oem gearing on the alpha you had was correct but the alpha uses a 3.5 pitch 7tooth driver not 3.0 unless you’re referring to the twin rail non-alpha which used the 3.0 pitch 7tooth so the final drive ratio on your chart is incorrect for the alpha being that low.
I know this is an older video, but I have the bikeman adjustable weights on a cat with just 4 magnet slots. My sled has a really hard time getting to full shift, I have a new spider and new weights so there shouldn't be any physical issues, I'm thinking its how I have the weights placed. I currently have weights (from heel to tip) 2-3-3-2. Would adding more weight to the tip help the clutches full shift out, or should I take weight off the tip and move it further down. I'm seeing 8200 rpms on cold days, and about 8100 when its warmer out. I also notice that the sled will achieve full shift on harder packed, freshly groomed trails, but the second there are more than 2-3 tracks on a trail, it just will not shift.
Hi Jake, I suspect that you're cured slightly taller than you should be and that would be why you don't see full shift out of your clutches, the question regarding weight placement would be do the RPMs behave the way you want them to throughout it's full acceleration event to full speed, in other words do you see any Peaks and valleys in RPM as it is traveling through its acceleration event with reasonably consistent traction. If it builds its best power around 8200 and you see 8200 consistently throughout it then it is likely not a matter of moving the weight around in the cam arm but rather considering gearing slightly lower. But ultimately it depends on what you are trying to achieve. There are trade-offs to every applied strategy. Anyway hope that helps, thanks for tuning in.
@@TheVOHK When I first got the sled, it pulled like a monster from all the way from 60-105ish and thats where it would top out. It litterally pulled so hard it felt like it was going to rip my arms of the sled. The sled only ran like this for about 1000 miles and then the weights started to get a groove and had a hard time shifting past the groove. I only have 1000 miles on my current weights/spider, but i'm thinking they could be grooved again. Ill get some new weights and try playing with the placement of the magnets, if that doesn't do what I want it to do, then ill take your advice and change the gearing. I have never regeared a sled before, is it as simple as just going 1 tooth smaller on the drive gear or maybe just 1-2 teeth bigger on the driven gear? Thanks for the help. Can't wait to start playing with weights again once i get my clutch puller.
Sounds like you're on the right track bud. Definitely check the condition of your clutch components, that can have a huge effect on whether or not it will reach end shift.
Need more date programmer / logger content please 👍🏽
Waiting for more videos on polaris from you 🙂
That was a good watch! Thanks for putting in the time to make this, I personally ride an axys still but am playing with the idea of upgrading. I think I’ll wait until the fuel pump and primary issue is fixed tho. Anyway, when I do go boost I def am going to go to you guys for tuning!
So Polaris is going to roll out all the 2023’s with failing fuel pumps?
That's all I'm taking care of
How about 5’k-9’k?
You should take a chassis, maybe last yrs chassis and make a straight tube chassis! I miss tube chassis’s and big bore’s. A BB tube chassis or a turbo but I’d prefer a 9xx bb
So who's blew up first
Nobody's yet lol
Do you plan on just doing a rear bumper or is a front bumper also in the horizon? Is the pump issue just on the turbo models or is it turbo and N/A models too?
Unfortunately the manufacturer we typically work with on our bumpers is undergoing some significant change and ultimately I'm not certain of the final outcome regarding bumpers... sorry.
What did the fuel pump guys have to say? @TheVOHK
I am currently running a ssi clutch kit on my axys, besides reading on forums that it works good I really had no idea what the rhyme or reason was to adding magnets to different spots on the weight. Thank you for this video!
Any noticeable difference with the ssi kit? I have one on the way for m8000
Will you be using the Bikeman weights in you kits? Great vid. Also will you be offering a 3k to 6k kit for the Boost sleds?
I really like the bikeman sniper weight but we do not include it in our kits unless we are doing a custom setup. We employ our own weights in all of our kits. Regarding boost packages yes we have packages for that altitude range.
More videos please
primary clutch?
Completely unrelated, but I REALLY wished "Skinz" would change their name. Whoever decided that was a good idea is HORRIBLE at marketing.....sounds like it should be a name for a condom company or something. I'll never own anything from them just because of the cringe factor. Gack.
😊👍👍👍
well done gentleman
Haaaaaaaa turbo spins backwards
After dumping 20k I’d like a little more of “it’s not the end of the world” answer when having fuel pump problems on a brand new sled.
Then dont buy a new truck
Right?! If I hear "we will get through this" I'm gonna throat punch somebody.
Is a 2.75 155 geared lower than the 3.0 155.I thought they have different driver diameter. Or do they run different gearing in the qd 2 in each sled?
Id love to know what model of acerbis wrap arounds your using, just dirt ones?
I know it’s not the type of videos you do but since it’s so relevant to clutching I’d love to see you do a short tutorial on belts, proper belt break in and most importantly when to replace a belt, what signs to look for indicating replacement.
Here here!
Does anyone use ethanol and turn up the boost on these?
The fuel economy gets so bad you don't get enough miles out of a tank. But yes you could
Great video, very informative! Question on the fuel pump issue… My boost has been making the loud pump noise the last couple days I rode it but I have not seen any codes up on the dash yet.. Would you keep riding it till codes come up or get it to the dealer sooner than later? Thanks!
I imagine within the week you'll have a response from the manufacturer regarding what the best course of action is. But for now if you haven't had a low-pressure code then continue riding it...
Awesome video guys
Great video guys!
So my question is today is the 3rd day I rode my boost was on the trail and would hit 45 mph and it would bog out will not go over 45 it keeps boging out
It sounds like you've reached that point where the unit won't tolerate the break-in fuel. But it could be something more serious than that and the best way to diagnose it is by logging the data. The VTI is a great tool to diagnose problems...
@@TheVOHK so if it won't accept the fuel what do I need to do take it back to the dealership??
Is it out of break in? If not just keep riding it until it is. If it is out of breaking you really should log that data and we can help you sort out what it is... feel free to email information directly to me erik@vohk.com
@@TheVOHK no its still in break in. Thank you for you're help and time I appreciate it.
Just wanted to let you know I think I figured out the problem on my boost. The fuel selector got switched. Switched her back today and man she came alive!!!!. Just wanted to say thanks again for you're help.
120 liters per MINUTE fuel flow, did I hear that right?
That's correct
Awesome video. Wish you expanded on the pro vs khaos chassis difference and what that feels like. You are one of the few that actually clocked a significant ammount of hours on them....+ 165 2.75 vs 155 3.0 and whatvthat does to a pro chassis.
We will try to revisit and elaborate on those differences in our next digest.. thanks for the input
There's videos everywhere on the Pro vs Khaos.
@@prowler13prowler I understand that. But them explaining the diff. between the two doesn’t negatively describe them. If they said “Yea the Khaos is junk,” well then no shit there’s gonna be a problem. But explaining the difference - what Polaris INTENTIONALLY DID - I mean WTF is there to hide dude!? How do you not get this!????
@@208SledHead still dont get why are you so personally invested in my fairly passing remark? To the point that you need to add childish ad hominems just so you can what...be a winner on the internet, be a better rider, smarter somehow? Based on the manner of conversation, the latter is something that may bother you. I may be a type of person who overthinks every purchase to the point that I can try to find, not 3, but a dozen similar or even identical opinions on the item at hand, untill Imake a final decision....especially when it comes to whats basically a $20k toy, and in a sport I am not profficient enough to be confident in every aspect. Go and ride dude....after you respond and insult me once more, ofc. Im off....
Need to make intakes like the axys boondocker intakes for all the Matrix sleds...the intakes on the matryx glaze over with snow like on the ayxs.
So my question is: are cans picking up power? Is stock a restriction post turbo? Thanks for the great video!
Stock is a designed restriction and if you change the backpressure or engineered design features you will change AFR and drivability
Due to space constraints the factory incorporates the diffuser in the silencer. This component is generally incorporated into the exhaust housing of the turbo. For this reason it is more likely that aftermarket silencers will cause a loss of power rather than any potential gain...
Is that same on skidoo turbo
No it is not the same on the Skidoo
@@TheVOHK so are you guys seeing power loss with the Diamond S ?
The only guys I trust to tune my sleds and diagnose issues! Great video guys. Cannot wait to get my VTI!
Wow, that is painful to watch. Need to learn to get to the point, organize your thoughts, and make a MUCH shorter video! Look up the definition of "Succinct" :)
