Unhappy Bike slowed down while riding with chugging motion (Not low gas)

Hello, my name is Nicholas, I am extremely new here. This is my first post so please be patient. I am a new rider as well, bought my 09 Ninja 500 a week 1/2 ago.

I've been riding around my area for awhile just fine getting the hang of things. Yesterday I decided to drive 24 miles to my sisters house, no issues. Then my brother-in-law decided to go fishing. I took the bike with me down some back roads and at a point my bike started to slow down. I would try to initiate throttle to it, and during this process it felt like it was "Chugging". I would still try to throttle it as it was slowing down on it's own and it would still chug. I'm not sure if it was chugging due to me throttling it. (I was trying to throttle it because I thought I was doing something wrong so I would try shifting)

As I was downshifting I noticed my oil light came on briefly. I would let it rest, start her up again and it was fine, and I would get a mile down the road and then the same problem happened. I called for a tow service to pick her up. And unfortunately it got dumped over on a flat bed because the driver didn't tie her down properly. When I went to store it at my local dealer, from what I saw my oil light came on permanently this time, and didn't want to stay running.

Long story short, bike started to slow down, I would throttle it, it felt like it was chugging, oil light briefly came on, started it after resting and it idled fine.

Please help, thank you,

Nicholas.

Oil level is about 1/4 of the way before I drove it. And after I drove it. I had just bought it from some guy an hour away from me and it sat all winter. I live in Upstate NY where we experience -10f temperatures and then 60 degrees immedietly after winter is over. He last rode it last year I believe.

It also had 12k miles.

The lack of any of the 4 things below will make your bike go chugga-chugga when it should be going vroom-vroom.

1) Fuel
2) Spark
3) Air
4) Oil

1,2 and 3 are all needed for an engine to run. Lack of number 4 (oil) will cause a good running engine to overheat and partially or even completely seize.

Double-check you have enough oil in the crankcase. I wouldn't start the bike again until you are certain oil starvation is not a culprit....

It was idling fine afterwards and would only go a mile down the road. Would start fine and such. After it got dumped on the flatbed, more issues were caused, but almost similar to my original issue. (oil light flashed once before, hence getting it towed, but now it's on perm.) So you think it may def be the oil? Do you think oil got to places it shouldn't have after it got dumped? It's currently at a dealer awaiting my insurance company to file against the tow company.

Also, where should the oil level be for a properly run engine in a motorcycle?

I quote you......"Oil level 1/4 of the way" This was checked on center or side stand? Can you post a phone pic of the oil level glass gauge for us ?

@NicNak remember, oil is checked engine off for (about 10 minutes after running) , on level ground bike on centerstand

Did you change the oil and filter upon purchase?

At 12,000 its first valve clearance check was due at 7500, an air filter visual check Was that stuff ever done?

Oil was checked on center stand. Unfortunately at this time I cannot post a pic of it as it is at the dealer currently. And I'm sure I checked it when engine was off, however it was not on level ground it was on gravel. I did check the level however when I purchased it on level ground, engine off, and it was at 1/4. I have not changed the oil and filter upon purchase as I was waiting for my inspection appointment and get it done there. I have no information as to when the checks were done, I did not receive any history of the bike.

I'll bug off knowing the dealer is addressing it.

You need to learn Scheduled Maintenance chart, I'd suggest a Haynes manual or Kaw owners manual.

In a service sense, better to be proactive and ON schedule, than reacting to stuff as it fails.

Right, I appreciate the help. Like I said I'm only a week and a half into understanding the bike. And as with my cars I've ever only had new cars and just took them in when told to.

Was just wondering what kind of fix would I be looking into, price wise and such.

The "oil light" is an indicator of oil pressure - or lack of it.

If the light comes on it means you don't have oil pressure, for whatever reason, and the engine will usually lock-up. Losing power would indicate increasing friction, and at times cooling will allow things to free-up temporarily.

If the light comes on you need to shut the engine down immediately. It may be too late if that is the cause of your problems.

Explain the issues to the dealer, and see what they say. Draining the oil and looking for bronze colored chips would confirm the engine bearings are gone.

I would also pursue the towing company for damages. They should have insurance for such things. It's not that difficult to tie a cycle securely if you know what you are doing, and they are responsible for the damage they caused.

On a side note - have you ridden before? How much experience do you have? I would suggest some type of new rider course if you are a brand new rider. There's no time on the road to learn the basics. That, and get all the gear and wear it all the time.

Welcome to the forum and I hope you didn't seize the engine. With that said, if you didn't and the issue is rectified I will suggest...any used bike, ALWAYS change the oil as soon as you get it home!
Just because people "say" they've done all the maintenance doesn't mean they did!

When I bought my used, 2007 EX I rode it 50 miles home. Immediately changed the oil and, I swear, that was the original oil from 2007!!! (And I bought the bike last summer!)

Also, look at the basic things...chain, tires, brake fluid, air filter...etc. These bikes are dated. I'd replace all of the fluids and air filter first thing.

Keep us posted!

From your original post I think that the problems are a bit easier.
Initial "chugging" may be caused by the tank vent in your gas cap. There are a lot of threads on this one. Basic symptoms are that after a period of time running, the bike just kind of stops. Let it rest, and it starts right back up.
Your initial oil light may just be that the engine cut out.

Now constant oil light may be caused by the bike going down. If you get a bubble in the oil at the pump, you will get a constant oil light. Burp the system or change the oil entirely. I would recommend the latter as a good thing to do after any time the bike is on its side for any reason.

^ Hopefully john is right.

His diagnosis is a good possibility, and is much better than mine.

I had a similar problem. I'll report back if I determine the cause.

Event:
I was on a spirited drive with several bursts of WOT. Started with a full tank and rode for about 2 hours. She started chugging up a hill and died when i pulled in the clutch.
She started back up in a couple minutes. Didn't need to use the reserve tank for another 50km or so.

Thoughts:
1. So it wasn't low on fuel, unless prolonged accel/decel caused the fuel to tip away from the fuel pickup temporarily.
2. I recently added the in-line fuel filter, put some MMO in the fuel tank for a good rinsing, and so the filter could be clogged up (fresh filters on the way).
3. I might simply have been running rich, and need to play with the pilots. This could exacerbate the first two potential causes.

Plan:
I'll examine the filter and go from there. I'd really like to adjust the pilots, possibly in conjunction with the FOGbox intake modification.
I have zero experience with carbs, so I'll be lurking the forums until I am confident I wont break a carburetor.

Opening the gas filler would tell you if you had a vent issue, as you will hear air rushing in if it's blocked. There is a mod to the filler cap that prevents the issue if I'm not mistaken. More info is probably in the Wiki.

If you were running WOT or close, Pilot Jets are not controlling the mixture. They control the mixture at idle and very small throttle openings only. Main Jets control the mixture at full throttle. The Needle Jet/Jet Needle mostly control the mixture at partial throttle.

When doing carb adjustments, think in terms of the throttle position (1/8, 1/4, 1/2, etc) and not the RPMs. It makes it easier to isolate the circuit that needs adjustment.

I found that when the bike tips over, it cavitates the oil pump, and in order to get the pressure back, I have to start the bike and unscrew the oil filter just enough to let some oil out, and release the air bubble, then quickly tighten it back up.
Recheck your oil level after shutting it off for a minute or two.
Just changing the oil doesn't solve the problem when the light is on constantly.

What happened was there was bad gas in the tank from the previous owner. When I had a tow my bike got dumped over on the flatbed. They took care of her extra due to the issue I faced with the tow driver not strapping it down properly.

The issue I had before the tow was bad gas. They ran her dry even the carb and fuel lines and gave her premium. The other small issue was after it got dumped, gas went to places it shouldn't have, but they cleaned that all out when they let her run dry.

Long story short, it was bad gas. Especially after sitting all winter.

Sorry for the late reply, I got her back yesterday, and it got inspected today with flying colors.

Thank you all for the help!

I know exactly what's happening. There is a vent tube the leaves the tank and runs under the seat. From time to time your weight on the seat can pinch this rubber hose and it chokes the carburetor vacuum/breathing system. A quick fix is to remove the seat, adjust the hose and reinstall the seat. There are two hoses, one is the overfill drain hose and the other is part of that vacuum release system.
Finding that sweet spot for the hose was the only way I got mine to go away. It still came back from time to time.

Not sure about the oil light though. Still sounds like a lean out.

Burp the oil.
Rokitrick has a good answer above.

Worse case scenario, you have a defective oil pump ( although unlikely), but none the less need to confirm why the oil light is on, IMO.
Oil light issue being top priority.
