Just completed a Stage 1 install last week with S&S headers, RSD intake, Rinehart 4" slip ons and a PV tuner. Was riding this past Saturday & Sunday and the bike runs like a monster. It invites me and seems to want me to ride in the 3K to 4.5K rpm range.
Stopped by the dealership for a couple of things and while there threw a mechanic a few bucks to install a set of chrome brake and clutch levers I had in my bag. The stock levers were starting to turn green,lol.
When riding off, noticed that both the clutch and brake levers seemed to be adjusted. Clutch was tight with no play in the lever, same with brake.
Well riding around two up a little down the road at about 3K rpm, I hit the throttle hard and the rpm raced up to 4500 rpm without increase in speed until I let off the throttle. It felt like the clutch was slipping. All I have to do to get it to slip is to just twist on the throttle aggressively at the bike's peak torque curve. I ride this way most of the time, aggressively.
Question is, is the clutch slipping due to the lever adjustment? Or could it possibly be something else that needs adjustment due to increased torque from Stage 1 and an aggressive riding style?

 

sounds like the clutch is adjusted too tight...

 

^^^^
roger that!
You didn't seem to think it was slipping before the mechanic changed the levers...

 

Take it back to the dealer and ask them what they may have done.

If you rode in and the bike was hot, it's not the time to re-adjust a clutch.

You are hitting your torque range and the clutch is slipping. So I'd suggest to stop testing it and causing more damage to the discs.

You may just need to do a standard clutch adjustment which is suggested to be done with the bike cold.

Now the upgrade certainly will create more stress on the clutch but you should be noticing the issue at take off too.

Since my cam upgrade I get a little squeal and can feel a slight slip if I take off from a stop too fast, two up. This is my next project. Either re-adjusting it to see if I can stop it, or I'm considering a new spring plate, or an upgraded spring plate in the clutch hub assembly.

Try an adjustment when cold and let us know if you were able to take care of the issue.

 

Thanks guys. I'm thinking that it has to be the clutch adjustment. Didn't notice any slipping prior to the lever swap, but wasn't riding quite as aggressively either. Haven't noticed any slipping from a dead stop at take off, but I don't usually take off very aggressive in first gear.

 

Quick and easy check/ fix to adjust 10 minutes of your time. And hand tools.

 

Could be your dealer overfilled your primary, if you had the primary fluid changed. Also, I went with the 145kg. spring plate and that made a noticable difference.
