Paragon secondary clutch

[Randy J]

other than belt deflection is there any other ajustments you can make tks.

 

[kanedog]

You can change the spring and the helix.

How old is the Paragon ? Older ones you could set the torsion as well but like Kane said ?
If newer it’s only spring ,helix and deflection .

What spring and helix for xp 860 174 3inch tra race primary c3 belt drive 2.52 gearing 8 tooth drivers . belt is running fairly high in primary not over reving only 8000 in heavier snow clicker 1 next time out in lighter snow engine was osselating on top end do i have to steep finnishing angle on helix byt need moer pin weight to load engine to stop osselating would like 150-200 more rpm but in clicker 3 any help would be great.

Post pics of primary and secondary. What pin weights are you running? What helix angle and spring color?

So i finally got my paragon taken apart it has a green spring with a 55degree straight cut helix three roller the primary is a tra race with 917 ramps short threaded pins no set screws and very light titaniam spring also have another primary set up i could try 915 ramps short threaded pins loaded up with purple purple spring 160-320 finnish rate what would you recomend tks.

I will pm you . I had a set up for mine and it’s way different then what you are trying to run.
I ran 9.8 grams of pin weight and a 100/230 spring .
415 ramps

Waiting for Kanedog to reply

I had the same issue. The oscillating could be the rpm’s going past the peak torque, losing power then dropping back into the juicy torque then past it again. Not sure about the xp860 but the 800Etec 7950rpms is perf. Anything over 7950 and it’s a dog.
lemme have a look at my notes.

I recommended the following for your exciting clutching journey.
1. Find the dyno sheet for the engine or call the builder. Find out what is the peak hp and torque rpm.
2. Add or subtract weight to get target rpm. I like click 2.
3. When the rpm’s begin to drop, like 7900 to 7800 to 7700, subtract some weight, like 3/10 of a gram at a time. Tune so it’ll will hold your target rpm.
4. The goal with the Paragon is to have the lightest spring without the belt slipping. The green is the lightest and it’s an 85/200.

Some Paragon points-
If primary weights are too heavy, it will pull the secondary open and make belt heat and hot secondary. Sled will be fast but it will go better with less heat. Make sure the primary is not being the boss.
Needs cleaning every 500-700miles. Backshift and performance will suffer.
The Paragon is the “brain.” It needs a balance of primary weight, gearing and rpm. If one is out of whack, it messes with the system.
The Paragon is very weight sensitive. A difference of 3/10 of a gram pin weight can make huge difference in performance. Go slow with pin weights when close to the target rpm zone.

From the sounds of it, you are on the right track. Keep up the good clutch reporting and keep the updates coming!

what helix did you use in your paragon

I was changing gearing along the way so I’ll give a long answer. The gear ratios are approximate cuz I did so many and can’t remember. All were with green spring.
1. 52/42 with 2.3-3.0 gearing. Lost oomph as the gearing got lower. Not enough load on the engine.
2. 56/51 with 2.8-3.0. Pulled better than 52/42
3. 55/53 with 3.65.
4. 55/60 with 3.81. Currently testing.
