Just got off the phone with my guys over at the Harley shop. I brought it in to get it dyno'ed and they told me that they couldn't do the run properly because the clutch is slipping. I put V&H Power duals and Monster rounds with the T-Man 555 Torqster cam on it and they said I need a heavier spring for the power it's putting down. They are looking for a solution for me. I figured come talk to the pros on the forum and see if anyone has encountered this issue. If you have a 2013 and you've done similar mods, have you encountered this problem and if so, what was your solution? From how they explained it to me, it is on the '13 models that they changed the clutch. Just looking for other options and opinions on what I should do. I knew it didn't feel right, but I couldn't explain what I was feeling. Now this makes sense. Any ideas would be greatly appreciated. Thanks guys!

 

I'm not aware of any clutch changes and as far as I know they put the same spring that is used in production 103 police bikes in the cvo bikes as well. Mine slipped in mostly stock configuration. So I opted for the cheapest solution to eliminate slipping. I installed the SE clutch diaphragm spring. It's a bit harder on the clutch hand. Especially in heavy traffic. But it doesn't slip any more either!

 

Found this on this site. I'm assuming this might be part of the issue maybe? I'll mention that to them as a possible option. Thanks!

 

if its a CVO you have a Hydraulic clutch, put the heavier spring in, the master cylinder for the clutch should be able to handle it.

my 12 CVO RGC did not have an issue.

 

Well, I got the bike back today and I didn't have to change the clutch yet, but they said it's going. They recommended I use it until it's gone, then I will have to replace. Looking at the AIM VP-Charger 120R kit. I called them today after reading some post and a few folks suggested them. They said they were working on a prototype for the 13 CVO's, but no where near production yet. If it's not done by the time my clutch goes, they said I could use this kit and just change out the clutch hopper with a older non CVO version and use this kit and it can handle the hp and torque from my upgrades.

 

I did read somewhere that the 2013 CVO were using some kind of a slipper clutch, only on the CVO's. I am sure one of the racing clutch manufacturers can assist you with your horsepower to ground issue.

 

It does have a slipper clutch however this is not your problem, been using slipper clutch on high hp race bikes for a few years now with no issues, it helps in down shifting without locking the rear wheel under heavy decel.

You have a clutch problem and Harley aint likely to cover it because of the mods you installed, you might as well throw down the skins for a new clutch and since you spent the money on hp, your gonna have to spend it on the next weak link in the system. HP = $, it's an old story we have known for years.

Now, I just gotta ask, why are you adding hp to a 855 lb road bike that you ride solo...

Maybe you chose the wrong bike!

 

Wasn't really out to "add" power to the bagger. Just did the basic stage 1 with cams and that was as far as I was going to go. Just wanted a little grunt. I have a go fast bike.
