I've manually activated it while stopped and could feel the difference it makes. Didn't make any change at all to the sound/feel of the bike. Maybe having Stage 1 helps?...

 

.."lets build a bike with an engine that will melt in traffic unless it is partially shut off"......ya..that's the ticket!....c'mon HD....throw in the towel, and build a water-cooled Touring model so we can have a choice!...I have an 05 88, and will NOT buy anything new from the factory until they get the heat problem solved...I thought the 05 was hot when I bought it, but the bigger motors are INSANE hot....

 

Have you ever been on a water-cooled motor in traffic? It's no magic bullet...

 

Mine never activated yet, must not have gotten hot enough up here in the NE.

 

As well as the noise the OP mentions, it can make your exhaust gases smell a little strange, too, although I haven't noticed this every time.

 

Not sure there is a problem if the bike works as designed. My last Dodge would cut out 4 cylinders when cruising ( I think more for fuel efficiency). I am sure the WPW stuff works, I just hate calling the EITMS a problem.

 

I guy tried to bag on HD over that saying ' see the damn thing shuts down it cant take the heat'.....too funny.
Go to I believe its page 42 on the EITMS........

 

Maybe it is not enabled?I'm farther NE than you and mine kicks in occasionally.

 

its not the engine that can't take the heat, its the rider. the eitms is about rider comfort....

 

I think the rear cylinder cut off is a dealer option. They should have asked you if you wanted it enabled.
