HOW TO INSTALL AND TUNE A CVTECH TRAILBLOC PRIMARY CLUTCH 

North Country Boyz SHOULDNT, he says. I have a distinct feeling you might!

@@LyndhurstXMRMY Bahahahaha. We will have to see how the upgrades handle the riding for this year. Scrambler returns to be this week and the work will begin for the rebuilding.

Yeah the 850's require a different spring and weight combinationnall together

@@LyndhurstXMRMY okay thanks man! I'm gonna try to find out what works with it

Exactly what i ran! I had a 1020 and 12 gram weights!

@@LyndhurstXMRMY perfect ill just stack these weights and get a 1020 spring! What was your shift out at im super curious. with the 1024 and 8 grams I have an insane amount of power taking off with 2700 engagement I believe and 6300 shift out but it just didn't get up there in rpms. It would top out at 80km (on speedometer, definitely not accurate) at around 6400 rpm so I feel like I should try and get it to top out a little higher although I don't want to lose that bottom end its super fun.

@@FakeDongers it would never shift out in high and id be doing roughly 110-112

Sounds like you secondary might not be set back into the helix forks properly

@@LyndhurstXMRMY could you explain the “helix forks”? I just replaced the secondary and it appears to work. It does adjust to rpm as it should. It seems to drive well other than it is difficult to shift between high low or reverse etc.

From what you said, "the belt is rubbing on the primary" that means your clutches arent put on all the way, in seeing the primary clutch is held on by a non compression bolt/stud, i dont think the issue is your promary. Your secondary clutch has a helix-shaft sleeve-spring-inner sheeve-outer sheeve then bolt or nuts. The inner sheeve has three slots in the back of it. The helix has three forks. The helix must have its forks inserted into these slots when installing the clutch or ut will put distance between the secondary and the backplate. Meaning your secondary will be further out causing your belt to rub on the outerr sheeve of the orimary! This is going off of what you are describing. Theres also 1000's of other variables.

You're gonna wanna go with a 1020 and 12-14gram weights. A 1024's engagement is way too high and a 1016 is basically stock engsgement

I meant your cvtech primary clutch

Amel Šahman hard to diagnose without seeing, did you pull the clutch apart before installing, try watching it with the belt cover off to see if its your primary or if its somewhere else? Did you use loctite on the primary bolt or a brand new one ?

@@LyndhurstXMRMY the sound of metal hitting metal like a klunk comes from the secondary pulley, only heard when I move out of place, I used an old screw without loctite, and I pulled to 89lb ft

What size bike?

Outlander 800r XT with 860 bit bore kit just trying to fined what Wights I need to run the 32.5s

@@williamfraser8527 id say a 1021 spring with 18 gran weights

Wat rpm dies it start to grab?

What spring /weights are in the clutch

Whats your tire setup

1020, im at 2400! And the instructions straight from cvtech say 70-80ft-lbs. the secondary is no more than 30

Any loss of power with the softer spring? And right on thanks! Looks like I’ll have to do some re torquing lol

No sir i can actually get up to 104km/h with my 27’s with my spring before i couldnt get past 84

@@LyndhurstXMRMY hmm I can hit 115+klms on my 07 Renegade 800 stock clutch.. I just bought cvtech HD primary. Haven't installed it yet still waiting for clutch puller tool 🤦🏽‍♂️🤦🏽‍♂️🤦🏽‍♂️

Id try the 1020 spring and 12 gram weights.

What’d you end up with? I have the 1017 spring and 12 gram weights and it hits 6900 rpm and once it shifts out falls to 6300.

I have 10 gram weights that does the same thing but not sure what my spring is came stock with the cvtech for 450 2021 what's an idea what it could be ?

Well yes, you have twuce the bike as i do and more aggressive tires

@@LyndhurstXMRMY got it dialed in perfectly at 22 gram weights, so if you include the sliders it will be 34 grams.shifting out at 74/7500, in high, and same with low under load, thanks!

What size motor?

Id do a 1020 - 18 gram weights

@@LyndhurstXMRMY ​​⁠I Just open the clutch and I have the spring u recommended but I have 20g wwights

@@Voffroading what size machine do you have, you might wanna try the 1017 spring

@@LyndhurstXMRMY I have a 1000 xmr 2023 with full titan hmf exhaust . K&n filter and 29.5 terminators tuned with Power vision

Try a 1020 spring

@@LyndhurstXMRMY ok that’s kinda what I was thinking, I’ll order one and see how it works. Thanks

Hey man, thanks for all the advice you're sharing. Can I ask what the rpm rev limiter is? I have a 2021 Outlander 650 xmr as well and had the 1020 spring with 18 gram weights but the machine does rev to high and activates the Visco-lok almost instantly because its so aggressive. its a 2400rpm shift out and the issue I was having was it was dragging to get to top speed almost as if not shifting out completely. I just changed to the spring to part 0951-1016 which is a lighter initial spring rate from 300 to 200NM but the same final spring rate of 1200NM and its shifting at 2000rpm. I used a 16 gram weight and a penny behind it to boost the weight to about 18.3grams. It shifts out at 7400rpm and comes down to 6900-7000rpm as it shifts through. Not sure I can get better than that. I would like to raise the RPM a little just before rev limiter but I don't know what that is. I have a 16gram and 18 gram weights right now. I may just put the 18grams in to get a little more RPM. I'd appreciate hearing how you made out.

Forgot to mention I'm running 31" Moto Havocs

@@mattgardner7869 I tried the 1020 spring and didn’t make much of a difference, went to the 1017 spring, brought my engagement to around 2200rpm, for weight I believe I have 14gram weights 7105. Shift out is around 7600rpm with 31 motohavocs and stock secondary. Pretty comfortable with it now

JorgeCanAm ATVs i reckon you’ll be looking for a while

I’m in same boat, you ever figure anything out

@@kaylee8975 ya but I got a different setup now I’m running 31 motohavocs

@@kaylee8975 a guy told me something about primary and secondary clutches with a whit spring

@@MagicJack999 hey man, I'd love to hear about this spring. What brand and part# if you have it or the a lead to the person you spoke with?

Is it slipping or are your tires burning out

Yessir! All cvtechs for canam atvs are the exact same, cvtech makes a gen 1(smooth weight cover) gen 2(ribbed and vented weight cover) both gens will fit any canam 2012+ you will just have to buy the 12g weights and 1020 spring seperatly

@@LyndhurstXMRMY your the man!!! Thanks

@@madrad3 anytime

yessir it delays the initial take off for more rpm on start off

@@oscarfuentes7548 did you remove you seecondary at all during this install?

@@oscarfuentes7548 what weights and spring is in your primary at the moment?

Thanks for the reply, i just went ahead and ordered a brand new Cvtech already tuned ,but i am curious should i run a diffferent spring in the secondary? I have a 570xmr Gade with 30” cryptids
