All 650's Bike won't turn over.

[shikiouji]

im sorry about the vague title..ill try to be as detailed as possible.
Bike is a 2019 CBR650R with 16k on the ODO. Has been dyno'd with an Akra full system and PCFC. stock intake filter. hi-flo oil filter. Motul 5100 Technosynthetic Oil (did this the day before). Oxford heated grips. thats about all the mods i did to this bike that isnt cosmetic

Day 1:
-Bike won't turn over
-after holding down the started for some time, the bike finally turns over but struggling real hard
-if i give the bike a quick blip of the throttle, the engine would die, but the longer i leave it to idle, the more life it breathes back, until the bike becomes fully rideable. thought i might've been a battery issue so i rode for the day before retiring it for the night
Day 2:
-did quick start up to make sure shes still not dead. didn't do a whole lot after...
Day 3: back to not being able to turn over.

im getting a whole lot of cranking, every once in awhile hear some chugging/puffs from the exhaust and it almost sounds like it might turn over eventually but i dont want to have to do this every time i want to ride my bike of course.

everyone tells me different things, so i thought what you guys might think of this as well? i only have 3-4 years of riding experience and ive only had my bikes long enough that i would need to give it new chains or rubber before selling to get a new bike. and this issue has been the most difficult i have faced so far. VERY new to this.

What I'm in the process of doing: right now my bike is stripped to the point that i can access the spark plugs. although i have to wait for the next day to get a deep socket to pull out the old spark plugs to be replaced. am i on the right track here?

Check the basics:

1. Battery voltage
2. Fuel (quality, pressure, volume)
3. Spark (do you have any, what do the plugs look like)
4. Compression (is it low)

99% of your issues get resolved in that tree above.

Try some fuel cleaner like Redline SL1 or Techron (high levels of PEA). You may have some poor fuel that clogged the injectors. Mix the concentrated ratio suggested for quick cleaning into the tank, then prime and reprime your fuel pump several times with some short bursts of cranking now and then to get the mix to the injectors. Let it sit overnight, then try in the morning.

I had this issue after winter storage last year, even though I used stabilizer and ensured it ran through the system before storage. In spring, it was a no-start; just cranked and puffed now and then. It was some crud that partially clogged injectors. Can occur with some bad gas at the last fill up.

will have a look at these, thanks folks. but as of right know my bike is stripped down to the point where i can access the sparkplugs. might as well swap them out to see whats up. it is NOT a fun thing to do..luckily everything else i've taken off the bike to access those sparkplugs, im extremely comfortable doing. will let you guys know what the results are.

I’m going assume when you say “turn over” you mean “start up”, correct? Because in my (limited) world a bike that doesn't turn over when you hit the starter button doesn’t “spin” at all to start.

So assuming that I am correct, based on your other discussion I think I’m safe, let me ask you 3 things:

1. I am curious when was the last time you started the bike before the symptoms started? Did you run it a very short time, like under 30 seconds? Did you start it up to move it, rev it, show some friends how it sounds, etc.?

2. You said you took it for a ride after it started, describe that ride. How long, rpms, sitting in traffic at all, etc.?

3. Any aftermarket accessories replaced to lighting, USB chargers, power plugs, etc. on it?

At that age and mileage, and based on your description I’m leaning towards fouled spark plugs. That’s a hunch, but that’s my guess so I think you may be on the right track.

@miweber929 excellent point above we should have clarified earlier.

The title suggests the motor does not turn over. That is battery, starter, relay related. I would label that “NO CRANK”.

If it’s cranking over, but not lighting off, that is “CRANK, NO START“ which will definitely eliminate battery/starter/relay and move one to the big three (spark, fuel, compression).

 

[shikiouji]

sorry yea its cranking while im holding down the starter but engine wont start.

am i allowed to link a youtube video recording of whats happening?

i swapped out spark plugs, no dice.

2. i took it for maybe a 2 hours ride, rode the whole tach a couple times.
3. usb charger and heated grips

1. Do you have spark?
2. Do you have injector pulse?
3. What is the fuel pressure?

 

[shikiouji]

couldnt find that forum rules on links that lead outside. so if im not allowed to post links to a youtube, please delete this post.
this is a video recorded of what my bike is doing when the starter is pressed and held. this video was made right after i put new sparkplugs in.

yea these...im going to need to figure out how to do. gonna take some time

Check side stand safety switch is work.
Tilt sensor
clutch safety switch
abs module (Pull fuse to bypass I think)

These items, I sure there is a way to bypass them in the service manual or how to check.

CB650F - Bike won't start after doing maintenance!

The bike's alive!! And it was the simple solution all along. The mechanic gave it varying amounts of throttle when holding the starter button for what felt like an absolute age (easily 10-15 seconds, definitely not the 5 seconds recommended in the owners manual). After that he revved the...

Suggest a look at post #21 in this no start thread.

That exhaust popping doesn't sound real good at cranking, plus you have blue smoke coming out. We're the plugs fouled when you pulled them?

So there’s a lot of cooks in this kitchen so I’m going to step away to avoid confusion as a lot of people are asking a lot of questions and giving you places look, another one isn’t going to help. You are good with a YouTube video link, as you found.

My thoughts and then I’m out:

1. You didn’t answer my question #1, have you done a quick start and shut off? If so, and even if you haven’t, follow the link that @ducatiman quoted that talked about a “flooded start”. Even though you swapped plugs that may still be happening.

2. It sounds to me like it’s not getting spark. @bishop gave you some places to look.

3. So that we are clear, the pipe, dyno, air filter and oil change were all the DAY BEFORE this started happening or was it only the oil change? If so, I’d go back and see what’s missing or unplugged, possibly the map sensor vacuum line on the air box.

4. I should ask, do you get a check engine light?

As I said, I’m stepping away to let others help, but answering these questions will help them.

The video sounds exactly as mine did after doing No. 1 above. Cranked, and crankned, and cranked a bit more using varying throttle. Finally fired and have never again had the problem. Hopefully yours is as simple.

 

[bishop]

If engine is flooded. Zip tie throttle open all the way and leave over night.

Try again the next day to start.

Unplug power from the Power commander, and see if it starts. Bike doesn't have to use the Power commander to run.

That won't work as the pc5 controls the injectors. Pc5 has to have power. I made that mistake once and panicked.

Your right. I got confused. Once I unplugged the Auto-tune by mistake and didn't notice for a while.

My plugs never made it to the 24000 km service I was running on 3 cyl. at about 21000 km. Your problem sounds like you might need a new battery with all those cold starts in Canada.
