roller secondary?

[Srxspec]

I have yet to find any roller clutch that is faster than the stock Yamaha one in 660'. The roller will be faster to 60' but the button will pass it up on the big end.

Wasn't the roller rooster originally sold by Bender?

Roller Rooster has always been from Advant-Edge Motorsports, but Bender Racing was a vendor/retailer who sold them for Advant-Edge for a few years.

That's was I saw as well, with all the testing we saw with the gun , it always came back showing that the rollers were slower.

They are a great set up for a trail sled though, if that's what you want.

It would help if you knew how to clutch a sled Ulmer......:wink:

It either under shifted or over shifted. There is NO physical reason a roller cannot be calibrated to shift from zero to full shift just like a button. There's less friction and they are more sensitive to changing load is all. The buttons are more consistent (less sensitive) and easier to tune because of friction.

Allen check this one out……tough crowd……

There is no way no how a roller shouldbe slower then a billet. If you use the proper angle & secondary spring there is no reason in the world why a steel helix on a steel roller bearing would be slower then an aluminum or nickel plated surface on a plastic puck! Geez; look at the friction co-efficient on backshift & to a smaller degree upshift.

Anyone can come to the test track in about 2 months and we'll bolt the Yamaha button secondary on and make some passes and get a average ET, then we'll bolt any roller secondary on and see if you can match em! I have Advant-Edge, Team, HC-X, Arctic Cat, and a Hyperlite. Call me if you need directions to the test track.

Again guys, it is MY OPINION, that the roller isn't as good for all out top end or a drag race. This is all from my own personal testing on the race track and on the track dyno. That being said I will have setups for the Advant-Edge roller for trail riding, where a better backshift makes the sled even more fun to ride, available next winter.

No offense to Turk, Hammer, or anyone else who likes the roller clutch!!

Al...no offence taken at al bud. This is just a good open forum discussion on clutching rollers vs billet. The only negative issue I see is people constantly using the wrong angled helix with too little or too much pretension on the driven. This happens a lot when tuning a billet set up but a lot more with a roller. I ran stock clutching on a trip last weekend on my Attak. Sled was pulling 10,500 rpm on hardpack. In 3-4' fresh unpacked powder I was struggling at 9k rpm. My roller set up would have done way better.

Turk is your roller set up faster than the stock clutching or just better backshift?

 

[Turk]

I get em running about the same when properly tuned but backshift with the roller is way better. I won,t say a roller gives any better acceleration but the backshift in general is way better.

 

[Tork]

Ah question comes to mind.

Is is better for a larger upshift, under light load, to help cruise MPG???

 

[Tork]

hey Turk,
I have Duanes Hi Tech Engineering ER (encapsulated roller) set up just collection dust in my garage. I'd like to play around with it. Should I order the same multiange helex you are using for me to experiment with?


This is a PM I got from another well known tuner on the site about a year ago.

The High Tech Roller is as good as any and can be made to perform nicely.

You need to get a helix from Duane that may be non-standard. I say "may be" because I'm not sure what he has these days.
Tell him you want him to build it and you're not interested in his opinions as to your needs. He will build it but it might take him a while???? Duane is great guy but has been abused by this industry, like many but he's a good man and a sharp clutching engineer.

Ask him to cut you a 38/32 and buy it from him, if you're really interested in dicking around with it.

You will need a to get the lowest rate and finish tension primary spring, that has roughly the same installed tension to maintain your engagement. Look to Ehrlandson, Maxximum, Bender, Houck etc., for this spring and let me know what you find.

Next, find a secondary spring that has as much torsional tension (twisting)as possible, coupled with the least compression tension (rate of rise) as you can find. Look at Polaris and Cat as well for this spring.

Then get a set of Heavy Hitters (preferable because I'm most familiar with them) or a set of the new adjustable weights Allen has. When you get all this, let me know and we'll take it from there.

I will stick with you and help you tune this. If you have a cell phone, I will even help you from here, while you're in the field testing.
