Tensioner Options For A Rivera Primo Game Changer

[Fat11Lo]

I know I know, should have never trusted the stock auto tensioner but in my defense there was hardly a mark on the original shoe when i upgraded the comp and installed the Game Changer. Now with RP out of business calling to get another shoe is out.

I was thinking about ordering this kit

https://twinpower-usa.com/blog/twin-power-adds-32-tooth-compensator-eliminator-kit.html

See if maybe I could use the tensioner with my current set up since the RP Game Changer sprocket and the Twin power sprocket are the same size (32 tooth)  or if there is interference with the Compensaver I may try the solid crank sprocket. My only other thought would be a shorter primary chain but not sure how to figure that or where to buy a custom length chain.

Any help is appreciated
Thanks

Nothing as far as I know of a shorter chain, don't think it would work out.  Be interesting to see if that other tensioner works out. I would for sure give it a shot.

There was some talk that they started up again.

[festus]

Don't like seeing that, How many miles on that set up?

Wasn't there a change to the shoe material? I seem to remember reading that they went to a black in color shoe that was a tougher material?

I just talked to Michael at Primo on Thursday last week and ordered a complete clutch hub assembly for a Brute III, I'll get it tomorrow.

I ordered a new tensioner shoe last week for my game changer got it last fri.  I went to there web site and ordered from one of there sales people listed on there web site. Hope this helps.

Yes it does, Thank you, I'll give them a call later today

I thought I heard the same thing a while back, then with all the talk about them closing up. I picked this one up on eBay a few years ago but installed it last fall, so it probably is the early material that some had issues with

   I don't think the problem started out being your tensioner shoe had sub-standard material. Look at your tensioner...that thing ratcheted up too tight causing your primary chain to become a saw blade and dig thru the shoe.
  If you get another shoe to replace the old one...take the time to set the primary chain with 5/8" deflection at the top...then mark the primary tensioner and have it welded in place so it can not over tighten.

I haven't ruled that out, I just wasn't afraid of it because it never over tightened stock, there was barely a mark on the shoe, I saw how you did yours when I was originally researching the Game Changer I just didn't think it was necessary. You know how hindsight works

   the stock primary tensioner is a one way tensioner. It will tighten the primary chain up from hard accelerations and decelerations all on it's own. The chain can not loosen back up on it's own to give the needed slack back, unless you go in and do it manually. Welding the tensioners wedge to the body with the correct chain deflection set prevents the chain from over tightening and causing what you had happen.

Makes sense, the 107 has a lot more than the 96 with 255's. Therefore I get on it a lot harder

Thanks for your insight Ray

   I was thinking about your thread a little bit ago. As tight as your primary chain had to have gotten to do what it did to that shoe...it would of definitely had your crank and tranny main shaft in a strangle hold. You might want to check them to make sure it didn't do any other damage.

[Fat11Lo]

Thanks will do

It happened pretty quick, I'm thinking 1000 miles or less, just got this motor together and tuned last fall

[topcat3815]

I never could get anyone to answer the phone, I sent an email to there sales people and ordered mine that way

Total wild a$$ guess here...... 

I've never seen the Primo tensioner shoe, nor do I have any idea how much primary chain slack has to be accounted for, but....

If you know someone who has one of the original Hayden M6 tensioners, with the original tall springs... it MAY take up the slack in the primary chain when adding the primo sprocket...

When Hayden first came out with the M6, the springs were too tall and the tensioner was way too tight (with the OEM compensator sprocket). There were many complaints, and people stopped installing them due to the issue. Hayden started making the M6 with shorter springs, to alleviate the severe tension on the primary chain with their first, taller springs.

They sent me the shorter springs for my M6, when I wrote to them about the problems I had read about the inability to install it with their recommended spacing...

Unfortunately, I sold the bike I installed the M6 in, and tossed the larger springs when I sold the bike. But here is a pic of the difference in height between the new spring set and older spring set.... Plus, if I remember, you could shim the plunger if you needed more height..

Again, totally unaware if this added height is even close to what you need... just a thought...

  I don't think that Hayden tensioner would work with the Game Changer 32 tooth sprocket. Stock is a larger 34 tooth comp sprocket. The smaller 32 tooth sprocket runs the factory chain and creates a sharper chain angle off the sprocket toward the tensioner shoe. This is why the shoe for the Game Changer is arched higher to allow the use of the factory chain keeping the same chain link count.

Good point, I hadn't even considered the angle off the smaller sprocket...

I said it was a wild a$$ guess...

I would really like to get ahold of one of the Twin Power ones for their 32 tooth sprocket. It looks very sturdy.

another week or so and we'll have the Twin Power back in stock....

I finally got back to this, a lot going on and it's wintertime here in Ohio so it was on the back burner

I wanted to update what I found and did instead of asking a whole bunch of questions and then disappearing without any resolution

I've thought a lot about this the last few months so this is what I did

Transmission shaft runout was pretty easy to check and it was less than .001",



The crank however was very hard to get an accurate reading



The outer hub that the comp sprocket rides on is a bit of a sloppy fit on the splines and moves .006" back and forth with the bolt run up but not tight. I took a cell phone video but I'm having trouble posting it. I measured runout with the bolt torqued and marked the high and low spots on the inner splined hub, then I turned the outer hub 180 degrees re torqued and measured again. The high and low spots did not correlate to the marks where I measured high and low before so my conclusion is the run out that I measured was more of the poor fit of the splines than the shaft being bent. The most I measured was .008" and the least was .004" but with the play in those splines I cant believe either number to be an accurate number for crank run out

Yes there was this is the new shoe they sent me

[Fat11Lo]

I ended up ordering the Twin Power 32 tooth Comp Eliminator kit because the tensioner isn't sold separately. The tensioner is a stout piece and fit nicely with the Game Changer sprocket and the Compensaver oil tray



I decided to give the solid sprocket a try and installed it, if I don't like it it will be an easy switch back to the comp



Now all I need is the weather to clear up so I can test ride.

Thanks for all of your comments and suggestions

[No Cents]

   If you don't mind...let us know what you think of that 32 tooth Twin Power set up after you give it a test ride.
I have gave serious thought about trying that kit when my comp or Game Changer shoe goes bad.
