Difficulty starting 919

I've been having more and more trouble getting my 9'er to start.

It has 26,500 miles, new battery, plugs and air filter but the valves have never been adjusted. When doing a cold start, it fires for a second, then dies just after letting go of the starter. This morning I had to try 5 times and gicve it some throttle to start up. Why is it doing this?

Do you have a Power Commander or other piggyback EFI system installed?

If you don't have a power commander, my next question would be if you've checked the fuel pressure regulator.

if you love your motorcycle, set it free.. if it comes back and hits you.. you highsided

Search the site, it's a known issue. If you have a PowerCommander fitted and it won't start when cold, remove the PowerCommander and see if the bike will start. If so, your problem is likely something to do with the PowerCommander.

That doesn't richen the mixture, it just adds extra air - it should be called the 'fast idle knob' as all it is intended to do is increase idle speed so the bike warms up faster.

It didn't do this for the past two winters. It's gotten worse over time.

I also have a power commander. If it's really cold I pull the knob first before trying to start. Works every time

i have a power commander but didnt have this issue until one night i killed my battery completely (left the heated grips on like an idiot) left the bike out overnight and came back with a new battery. - started the bike but ever since then ive had the power commander issue of having to hold the starter switch in longer and longer lately it seems like 10 seconds or more. If its not bad for the starter im not hugely concerned but that must put extra wear on the starter.

Going to take the ignition switch apart and clean it up a bit see if that helps

Pulling on the knob doesnt help.

This is most likely not a pc issue according to dusty at dynojet.

On second thought, my heated grips have drained my battety dead several times....

Dusty at Dynojet is wrong... Almost every 919 that lives in a cold climate and has a power commander has had this issue... search the forum and you will find many documented cases of it...

Doesn't even have to be a cold climate, mine did it too, took the PCIII off and now it fires right up every time, of course my mileage dropped at the same time

Rob makes a lot of good points here.https://www.wristtwisters.com/forums/...s/66018?page=1 Basically saying the battery is overdrawn by the headlight when it's cold out. Causing the no start issues. He says to pull the headlight fuse and try to start it. It may stay running. Then he explains how to fix the problem with a diode

Haha, well shit. Try to clean up the inside of the kill switch yet? The contact points to be specific.

It cranks like crazy but once it fires it just dies. I didnt install the pc so how do I test it?

Still dont see how that can be the problem ive had it for 3 seasons and only now is it giving me problems.

You need to remove it to see if it's the issue.

If you don't understand take the time to research the problem. The information is out there. Over time things change. In this particular case there is a known problem that is caused by contact corrosion over time. Everything does not last forever. Have you ever heard of intermittent electrical issues in a car?


Hard starting could be caused by a number of things but there is a history here with this bike that is documented on this site.


It's disturbing to see someone asking for advice then criticizing the people trying to help because the answer isn't the one they want to hear.


Sorry for being so blunt, but if you don't take the time to understand you will never fix the problem.


Then don't complain to the forum that is trying to help you.

I was just thinking out loud but your advice it duly noted

Disconnected it and it fired right up so fast I could have forgotten it was a Honda for the past year. That's kind of a bummer.

Really appreciate it guys

That sounds like the Power Commander (in your case) is commanding too rich a mixture, because all that knob does is provide extra air.

As far as I can tell, it's all zero's on the map for start-up but maybe it does something to the mixture anyway?

Either way I'm not real excited about keeping it on my bike. Never had a PC problem but seems pretty inexcusable to me.

This is very easy to circumvent: you can either just blimp the throttle on start up, or you can hold down the starter button for 3-5 seconds after the engine fires up. Been doing the second option for a few years now with no ill effects. That's with 45.5k miles on the clock. The benefits of the pc3 and custom tune far outweighs holding down the starter button for a few extra seconds.

I've had numerous talks with dynojet. It's sad to hear that they STILL deny the problem is with the pc3 when it very clearly is. Dynojet won't fix it and any "fix" they claim just does not work. One of their supposed fixes nearly bricked the pc3. That was when I started experimenting with the starter button and discovered it. Is it really a "fix"? No. But it makes it a non-issue now and still is after several years.
