JOKERS IMPALA wants to know Dino or Syn?
Cough Through Intake

I have an 09 Night Train, quite a few times when I go to start the bike it takes a little longer than youd expect for it to start and sometimes if either I let off the switch or even sometimes during cranking it will cough back through the intake and blow a mist of oil (not sure if from the A/C or build up from breathers) down on the right side of the engine. I have a Roland Sands A/C and BSS exhaust. Just wondering what is causing it to cough back through the intake, just figure a bike with 3000miles shouldnt have these issues.

mine did it more when it was hot and it helps with starting, it puts less stress on the battery and alternator. but the cams and new push rods your looking around 850 then the install is usually another 450, buts its worth the money. bike starts easier and the power is alot nicer. no more down shifting for passing car

No doubt having a set of cams would be great but again not in the budget anytime soon

Same thing happens on my ride. Just hold onto the switch until it starts. If it starts happening more frequently, even when you don't let off the switch early, then you may be due for a new battery...

You: "Petrock, it hurts when I do this... "
Me: "Then don't do that..."

its a flaw the hd motor company built in the bike so you would take it back to the stealership to spend money so they can diagnose it and then charge you even more money to fix it. have you done any modification to the bike... if so what did you do?

Most times an intake back-fire is caused by a lean a/f ratio. I'd have the fuel enrichment on idle air control valve checked.

I can't believe the bike needed a battery already. Usually you should get about 5 years or so with a pretty much stock bike, heck even if it isn't close to stock if its tuned some what right. Your bike must still be under warranty ? Make harley fix it .
