This morning I had an issue where my 939SS was hard to start. Not sluggish like a bad battery, but more like the engine just wouldn't catch. It took me at least 10 tries of press-and-hold the starter for two-three seconds to finally get the engine to finally catch.

This is how my '94 SS behaves when it's cold outside and there's no choke on the carbs, which make me wonder - it was 70F when I parked last night, and 54F this morning when I tried starting it. I wonder if the ECU didn't pick up the temperature change when I turned it back on.

Has anyone else had a hard time getting their bike to start when the bike is cold and/or it's cold outside?

I saw a reading of 55F on my weather app this morning, but the bike start fine at first trigger

Do you connect to a battery maintainer charger over night
No. On a brand new bike with less than 300 miles, I should not need to put it on a battery tender to park at my place of employment for 12 hours. Each of my rides so far has been over 15 miles, more than enough to recharge from starting the bike.

If it's a one off I wouldn't worry about it
Monitor it over a few days
Still giving you a problem check the battery
Most modern battery chargers will indicate the level of charge in the battery(well mine does anyway):wink2:
Fingers crossed it's a one off

The diagnostics at the first service should be able to give a more definitive fact, until then I suppose we are all guessing the problem. I too had an issue during the first 1000km where the DQS and DRL switched off on their own and the errors were in memory of the ecu. It has not happened since and the same could be with your issue. It's like the ecu throws a wobbly.

Did you find out what the issue was? I'm getting a similar issue the recently, but summer here in New Zealand

Some people with other Superbikes have sometimes similar Problems.
Try this:
turn the key on and wait some seconds (So the System pumps gas to the injectors) turn it off and on again. Maybe do this 2 , 3 times, than start!
This can help!!!

Mine did that hard start thing...it's not the battery...it'll pop maybe once or twice and die, and it'll do that 4-5 times til it finally stays running...

Here's what I do: turn the ignition on, give it like 5 seconds...don't open the throttle...hit the starter and at the same time, open the throttle slightly...the trick is to open the throttle only when you start cranking...not sure why that works, but it does every time, for me anyway...

Interesting...does it require you open the throttle, or just the way you prefer to start it?

It should start quick and clean without touching the throttle.

Wait. Using the throttle on a fuel injected bike does nothing during cranking...just like a car. The ignition and fuel delivery is completely controlled by the ECU. No pumping or twisting of the gas like in old non-computer cars required. Now, I do see where it's possible that the fuel pump does ready itself after initial key on, but will it do it over and over? Seems like that would lead to possible flooding.

I've been having this issue with my Monster for years during cold weather. Most times it acts this way, it ends up killing the battery. I'm going to try starter fluid this weekend and see if it gets it going.

Agreed. You shouldn't have to touch the throttle during starting.

There are a million posts where it shows people have to start their Ducatis this way, carb'd and FI'd. For others, like me, it doesn't work. I don't know what it is about Ducatis and their starting issues, but I wish Ducati engineers would figure it out. They should be embarrassed that so many people are having this problem.

This thread actually sealed the deal that I'll be getting a Honda next, considering I've been dealing with this issue for over 5 years with my last 2 Monsters. During the winter, my Ducs have been living room decor because they have such trouble starting in cold weather.

Wait. Let's not do anything brash, yet. Mine starts just fine and hasn't been ridden in over 3 months, now. It sits in an unheated garage. Granted it rarely gets below 40° in the garage, but it starts all the same. :wink2:

LOL, I've owned 2 Ducatis in a row that had the same problem without a fix, and if I know that there's potential for it to happen again, I'm apprehensive to take the risk, because it'll be just my luck.

Besides, the '18 CB1000R is a hot one.
