2021 Engine Stalling and Hard Starts

Been reading too much about the 21 having starting problems and stalling.
Mine stalled as I was pulling off a stop and I dropped the bike. Not happy.
So I am reading about all sorts of solutions, but I am not seeing any that are really fixing this problem
What is going on with the 21 bikes?
If I continue having the problem I will probably sell the bike or trade it.

Do you have a BS6/Euro5 ? mine has no issues at all (exept for foggy dails/meters). If you have prublems with such a new bike you should really visit the dealer and let them sort it out...

Someone in another thread mentioned a re-flash of the ECM helped solve some cold start issues. Had to talk to the dealer and ask for that update.

How many miles are on your bike now, and services completed? I did the Iridium plug swap, and that (along with putting on the miles) solved all the early stalling for my 2020.

Dang. Just installed the Iridium and I see a big improvement. I will try a cold start, but she idles well and no problem with a quick throttle blip. Hmm. Could this be the problem?

75 miles on the clock and it stalled once and you want to sell the bike and the Indian bosch plug sucks?
Mate it’s all Indian you might just want to sell it now 🤔
Will save you and us all the heartache as you go into meltdown if any other problems hit.
Buy a 2022 KLR 650 and be done with it ???

Only joking. Only joking.😄

I have iridium plugs on my bike as well.
My wife’s Nissan SUV needed plugs and we went with NGK iridium two weeks ago. My wife who is not technically inclined didn’t know of the change and said the car is so much smoother and asked me what was done?

Hang in there the Himmi gets better as you put more miles on it👍

[P.S. mine is a 2021 built (but not Euro5 - same as yours) and no stalling issues so far. I do however plan to remove the extra plumbing on the skid plate at my 5000km service]

Always put a new or good plug in when running issues occur , normally sorts it out. Try to use a quality genuine plugs like NGK , it's worth a tenner

Only 75 miles on the clock, yup, be patient and get through the 300 and the first service. The valve check/adjustment at 300 also will likely help. Glad the Iridium plug showed a marked improvement. This is a good platform, needs a break-in period and service at the proper intervals. Now over 10k miles on mine - just love this bike.
 
Looking at that plug, it's running well rich. Shouldn't be black as that, surely?
when I pulled my original plug at 3000 miles it was a tan/grey color, Replaced with iridium. (I have installed the booster plug for reference, and the plug looked in good condition, correct gap etc)

Here’s some quick references to reading a motorcycle spark plug:
  • Light tan spark plug: Good mixture.
  • Dark brown or Black Spark Plug: Too rich
  • Black, oily Spark Plug: Oil fouled (see valves or piston rings.)
  • White, no color on spark plug: Too lean.
  • Good running conditions: If everything is good, the spark plug should have a tan/light brown color.
  • Rich running conditions: If your engine is running too rich, the spark plug will be black and sooty.
  • Lean running conditions: If your engine is running too lean, the spark plug will be white.
  • If the spark plug is black and oily, they are oil fouled.

Not oil - not wet and shiney.
Army_eod, can you post a pic looking more at the electrode end of the plug?
So that we can better see it's condition.

My plug was light grey before fitting my booster plug, now its tan and runs a lot better. Is that a Briggs and Stratton plug you have there?

KTM AL - Thats only a library pic to illustrate my request for the above. Wouldn't know what brand it is.

I’d agree - with so few miles that’s light brown enough to not cause any issue. I wonder if it was poor quality of spark that caused the stalling. Does seem odd.
