Dropped rear cylinder

While down at bike week in daytona a buddys bike dropped the rear cylinder and then died. Upon startup again it sounded like it had no oil in the motor. Took it to the local dealer and they said that was normal and it was a safety measure built into the bike? Has anybody else experienced or heard of this? What are your suggestions?

The new HDs have an automated rear cylinder shut-down when engine temp goes too high (a good idea, especially with 103"). This feature is activated if you twist the throttle backwards while sitting. Were y'all sitting still for some time waiting for traffic to clear so you could move again (or something like that)?

If you think that's probably the situation, then it's not supposed to make the engine die so the dealer didn't account for this. Your bud should probably go back and make them look into why the engine conked out instead of merely shutting down the rear cylinder... plus...

It's not good to let an air-cooled engine get so hot that this new safety feature is activated (the Main Street crawl can get'cha ). I hope your buddy didn't just keep letting her run on and on until she finally died even though the new feature had tried to reduce hazard to the engine.

Bring 'em home or send us back!!

I thought it was activated when rolled forward. If you rolled it back you would just rev up the motor.

I thought it was an auto feature once it is turned on you do not need to roll it forward each time to activate it.

Thanks JtB... I forget about that. In fact, I can't remember if you need to set it each time you come to a stop, each time you start the engine, <whatever>. I also didn't clearly explain that, to me anyway, "backward" was opposite to the direction a rider typically forces the throttle grip. I probably should have said "Read the manual to make sure..." someplace since it's indeed not a truely accurate or totally complete summary.

Bring 'em home or send us back!!

Re: Dropped rear cylinder

Yes it was due to idle and no he didnt just keep letting it go till it died it just died shortly after the cylinder shut down from my understanding. I wasnt there to say for sure I just posted this for him. However with the vast knowledge of this group I figured this would be the best place to get a second answer.

Outstanding .

Then I stand by my original suggestion - your bud should probably make 'em explain why she died instead of merely going into the parade mode.

Re: Dropped rear cylinder

Thanks I'll let him know and probably have him take it to the other dealer as well.
