09 single cylinder run
ok 5th time posting a charm? \\; errr I hope it goes through \\; lol \\; \\; try to break it down to small post and see how it flys
 \\;
What is the real deal on this 1 cylinder off for the 09's? \\; I understand it is to reduce heat, but this is a 2 cylinder engine.

RE: 09 single cylinder run
The Harley site is all jacked up again, but I don't remember seeing a whole lot of info on it. \\; Google is not doing much yet. \\; Just hoping to read more info on the shut down system.
Does it operate electrically killing rear spark and fuel? \\; But how reliable is that system? \\; Does it operate on heat/temperature? \\; or RPM? \\; I mean, what if there is a situation your

RE: 09 single cylinder run
at idle and you need full power immediately? \\; Is there an over-ride feature? \\; I assume Harley tested the tar of of that system before delivering to the market? \\; What does it do the the front cylinder with the extra force there and dead rotating mass in the back cylinder? \\; Will the 09 engine need to be rebuilt with much lower miles then the 08's and previous? \\; Gas millage rating are the same so I guess absolutly nothing there.

RE: 09 single cylinder run
When idling, to avoid excess heat, the rear cylinder cuts off on the '09 touring bikes. \\; I believe this was a recall an upgrade on the '08 Ultra Classics following complaints of excess heat and over heating engines when idled for long periods. \\; The 2nd cylinder comes alive with the throttle advance. \\; I have not heard of any complaints from people who have Ultras with it.

I have that featiure on my 08 RG, and I can turn the feature on or off. At idle, when really hot, the rear cyclinder turns off. As soon as you crack the throttle,it comes back on right away.

Actualy started on the 06's. Idle Heat Management. First level the idle drops by 100 rpm, 2nd level another 100 &\\; then is kills the spark &\\; fuel to the rear cylinder every 3 go round. Even with a PCIII, if head temp got hot enough.
