I would think a 50% increase in clamping pressure would require a 50% increase in clutch effort. One is fighting the other, so I think it's got to work 1 to 1.

Yuo're not scaring me away from it, so I'll just have to let you know! My power will be to the ground! Hoist!

They do get very hard to pull in at high rpms.  Try it and see what you think,  I only posted my experiance with them. I think they fill a void but not for what we do.

Not trying to rain on your parade my man. We need you to try it out and report back to us that aren't running on the same curve as you. I've got time for you to find the way, then I can follow your lead.

Since I'm not going crazy with this build, I'm hoping, as Steve said, it fills a void. If it works as advertised, it'll be OK for my purposes. Next step would be a complete clutch replacement. I was hoping to wait until more things are available for the redesigned '07 setups before considering a clutch replacement. Until that time, I hope this does the trick! I'll let you know what I think of it. Hoist!

I guess a question to ask " is it a money issue??" if so try it if not buy the primo as it will work , it will provide less effort and it will not slip period

Well it isn't too expensive and doesn't require removing the whole clutch assembly and rebuilding it. Fairly easy install. Since you can only buy the clutch parts, and not an entire replacement clutch assembly, I wanted to wait and see what comes out for these '07's. I was looking at the King Kong Clutch, but Baker isn't sure what they're doing yet for '07's. If this thing works OK for now, I'll live with it. If it doesn't hold up to the power, or becomes too much effort, it'll be time to look at replacing the clutch. Hoist!

Well we have hd some that we could not get in through the derby cover so we still had to remove out primary cover, at that point you are about 1.5 hrs of labor to install the primo. If they are bought through us and customer does nto have access to a press we install it for free and ship it back

Thanks Steve. Something to keep in mind. I'll let you guys know how the VPC works out. If I don't like it, the Rivera might be next. I have the Pro Clutch in my other 2 bikes, and know that it would hold up fine, and it has less lever effort than stock. Hoist!

I wonder how much stiffer it becomes, say at 5,000 rpm?

Chief

At 5000 rpm the Frontier generates 132 ft lbs of torque (same as it does at 2500).
At 5000 rpm the Frontier generates 125 horsepower. (I just checked the dyno sheet)
I have made many a shift at 5000 and never thought a second about it.
Does that answer any question about the rpm increase vrs the effort to pull in the clutch, I'm not sure.
One thing I am sure of is that ocassionally things are flogged to death about a potential problem when there really isn't one.
But what do I know?
Mine has worked great for the past 4500 miles and I'm happy with it!
That's the criteria for performance in my world!

 


And Hoist
I didn't use the 92 for a good reason. Call me later and I will explain!

Chip, someone told me that you slept with that dyno sheet under your pillow!!!   

Hoist, I'm with you on this one, I'll try it and see. Sounds like Chip has no problem.

Chip,

I just asked a question because I was curious. I'm sure its a great device as I have read great things about them in all of the rags that have installed them for tech articles.

Not under the pillow, it's the pillow case
Had  pillow case's printed up with the dyno info printed on it.
Have Nancy's results printed on her pillow.
1200 count material!
When we have a pillow fight it's all about horsepower!

Sometimes my responses appear a little blunt.
That's usually the way I mean them.
But "please" remember, the response is directed to the subject matter not to the poster.
If I offended you then I apologize!

No offense taken. I just wanted you to know I wasn't flogging the whirlygig just because I was asking a question about it.
