Energy one clutch slipping

One other interesting relevant point
The jutter spring actually is part of the clamp force. So remove that and you now have less clamp force all the rest of the things being equal but more friction area.
I will use their spring when I do mine.

Not sure how the judder spring is part of the clamp force.. It is designed to preload part off the clutch to give a more progressive feel.

The clutch slipping could be the result of oil but I'd suspect a stack up issue also..

Whats your clutch stack up height?
You can have anyones new clutch plates and if the stackup is not correct they will SLIPPPPP....

They should stack flush with the top of the clutch basket. Max below flush is .050" down... beyond that anything can and will slip...

I told him to check and we will mix and match steels to get it up if need be

I'd go along with Max on the judder spring giving a more progressive feel. Mine is either engaged, or it is disengaged. I can feather it, but it takes a very light hand, and even then it tries to just hook up hard. That's not a complaint by any means. I like this clutch a lot.

  Dan mine hooks up real nice

IME:
Even with the 10 plate EO and VPC 92 the early arrival 120-140 foot pounders need a heavier clutch spring.
Effective centrifugal advantage for the VPC needs 3000 RPM (engine) or so.
A 380 lb spring is available from EO.
A 480 lb spring is available from AIM (the VPC folks).

As mentioned, stack up height is very important.
A move from syn to non-syn can help too.

Beyond this, go with a Bandit or similar.

My 113 SG '06 has a stock clutch with a vp92c.  I've started getting hints of clutch slippage and thought I'd nip it in the bud before I do sturgis.   I installed the Energy One plates and am now getting horrendous slippage.  The same spring and vpc are used in each set-up. I've used mtl in the primary for years.  I soaked the friction plates for about 30 minutes before installation.  Why is this slipping more with the E1's?

I did receive a call today on this exact problem and hope the symptoms that you are having and the information I give you will help alleviate the problem.

If the bike is several years old and has 40,000 miles or more, ALWAYS replace the clutch spring.  Don't just put in new frictions and steels and expect everything to work fine.  The spring is a large part of the clutch.  Without the proper engagement you will not get full clutch action.  Basically, the material that they use for the diaphragm spring isn't the best material - not that the same material they use for valve springs.  The spring from getting hot/cold hot/cold will eventually lose its tension.  So yes, you can have the proper stack height which is 1.835" to 1.850" and these are OEM specs which we build our kits by - and if the spring has lost some of its tension, then it will not apply the proper tension, therefore resulting in clutch slippage at certain RPMs. 

I hope this helps.  Not trying to create waves, just trying to help solve the issue. 

If you have any problems with any clutches of any year, or belt drive units, we do make the plates for BDL, Rivera Primo, Baker, Sputhe, Bandit and Karata, we are happy to help when we can.  I am only saying this because I get a lot of calls on Big Dog bikes - which the early models are Rivera Primo and the late models are Baker.

Thanks for all the kind and positive words.

.....and mention HTT when you order

stack up was 1.844 and I installed a new SE spring.  Still slipped.  I installed a new SE Friction/Disc kit with the same SE plate, and no slipping.  SE stackup was 1.850.  I leave for sturgis in six hours.

 Max, Isn't that SOP for most after your first call?   

Sorry couldn't resist.      Rick

1450 miles to get to sturgis and the SE had zero noticable slippage.  I'll have to check stack-up when I get home.

They musta new I was going to contact them.. They closed up shop.. Max
