All 650Rs Oil leak

[Jp8]

Yeah goblin I think I had been riding for a while with the leak as I never saw any drips on the garage floor. I will contact the dealer. It’s an awesome bike I just hope I don’t end up in an infinite loop of getting new pumps that leak…

Don’t worry about it to much, your problem is solved with a new pump. Just don’t agree with only an o-ring replacement, let them know that you know about this issue! The Honda bikes are solid 👊

I’ll make sure they replace the pump, thank you for the advice!

Hey guys, I believe I have this same water pump issue with my brand new 2023 cbr650r 😪. The day after a 2 hour long and very “spirited” ride in the mountains I checked my oil level and the dipstick was dry (coolant level seems to be steady). These pictures show what I found, does this seem to be the same issue and has anyone else had it happen with the 2023 models? Of course I’m well within the warranty but I’m not optimistic about replacing seals or the whole pump after reading this entire thread… This is very frustrating and I’m worried if I’ve done any damage by riding with low oil level.

Hello.

Sorry to know you have the infamous oil leak.
What you show on the images is a very small leak and won’t be enough to cause your oil level to drop, 2 or 3 drops of oil are enough to cause this but not drop the level fast.
Probably you are measuring the level the wrong way. Don´t worry about riding the bike. Just go to your dealer and show them the leak and ask for a pump replacement. In the meantime, you can ride it with no issues. That is a minor leak.

Yeah looks like your pump is leaking oil, but I also see some oil coming out of the oil sump sealant. Let the dealer sort it out. If your dipstick is dry then the bike is leaking for some time or the oil level was low to begin with. Glad the bike is still under warranty!

No, the oil leak tends to migrate through the sump sealing line, because oil finds it as a progression barrier ans travels throug it.
Mine was the same.

Agree with the fact that replacing the fitting O-ring doesn’t fix it.

Disagree on the affirmation that the pump replacement will (absolutly) solve it. Many, including me, didn´t had it fixed with the pump replacement!
Seems that the pumps in stock, have a similar failure rate than the ones fitted on the bikes.

I don´t know what to say about this and other coolant pumps quality. I tested the new Honda Transalp, the engine cover was covered in blue gunk (dry coolant), recently saw in a show room a new CB1000R with a dry blue puddle beneath it! A close friend 2022 CB500X is also leaking oil as ours!
What is wrong with this Honda?!

Make sure you’re checking the oil with the bike level - I doubt it would leak so bad to be bone dry unless you were riding hard like this for 5k miles or more without topping off, but yeah looks to be the same issue. I also had it on my 2022 CBR650R. I ended up trading the bike for a Ninja 1000SX because I thought it was absurd Honda hasn’t fixed this issue for years and probably never will. I was able to trade the bike in, with the oil leak, at the same dealership I bought it at with no issues, they were aware of the problem and still gave me the fair value price. The N1k obviously makes more power than the CBR650R but I do miss the bike a lot because I’d done a lot of work to it to make it mine. I’ll probably never buy another Honda again after dealing with this whole situation.

Sup y’all!
Interesting reading this tread. I have a 2015 CB650F with 70k km and with the infamous droplet of oil. Living with it, but this will be my last Honda.

Do you expect others will do better?! Hmm, not sure they do.

It’s your choice to swear off Honda but just to be clear the “infamous” droplet of oil due to a poor water pump connection is a ‘19+ phenomenon and normally doesn’t affect the 14-18 models.

With 70k km, or like 45,000 miles, on an almost 10 year old bike I’d say an easy to change water pump is a minor repair, and hardly indicative of a massive issue. My ‘16 Silverado with 105,000 miles on it just needed an alternator that i installed last week, I wouldn’t not buy a Chevy because of that. Waterpumps, alternators (or stators), tires, shocks, bearings, bushings and brakes are all pretty much wear parts.

But that’s your call to make.

What I experience, for the 2nd time, is not a fitting leak. It's a pump shaft seal leak. I was able to confirm that the oil is comming from the weep hole. But in the replacement pump, the leak is really minor. I can only see the bottom pump screw is oily. Nothing major. Apart from that, the bike has been totally fine after 29kkm.

Maybe it is just an excuse to try the mt09 😅

You don’t need an excuse to ride a CP3 Yamaha. Just know, though, you’ll buy one after, just be prepared for that. I don’t think there is a much better engine in motorcycling. Probably ever.

I noticed just the other day mine was leaking in that same general area. Maybe not exactly where yours was leaking but close enough. I think it may be the water pump inner seal as well. I'll have a shop near me check it out.

Same cause discussed here. We don't need to say more than what you can read above 😏
Just ignore and keep riding. Mine is now 31kkm and there is always that oil drop. But nothing more than a few drops.
Besides this, great bike. Just gas, oil and tyres.

Turns out that when the water pump was originally installed, the O-ring was pinched, causing it to fail prematurely and creating the leak. I don't think any oil leak should be ignored. Especially one that could worsen over time and cause the oil to splash onto the rear tire. Could be really bad.
I got the water pump replaced and voila! No more leak.

From my experience and others shared here, I can say I'm pretty confident the oil is not coming from assembly o-ring. Many here tried that fix, with no result. Seems the oil is coming from the pump internal shaft seal. Mine is leaking from weep hole, can assure you. If you understand how this pump assembly works, you will find that there are 2 seals internally, one seal coolant and a 2nd seals engine oil, from the opposite side. Apparently this 2nd seal is not completely capable of keeping engine oil in and then it leaks from pump weep hole. That´s why it was left there, to leak residual leaks from both coolant and oil, avoiding that they leak to the wrong side.
The level of leaking I'm talking about does not leak to the tire. It doesn’t even drip, it´s just moisture around the area.

Hello all,

wondering if anyone else has had this issue. I noticed an oil leak a few week ago Honda replaced the water pump o-ring where it goes into the crankcase. Been on it again and noticed it leaking again today after id had a ride out.

I thought I had this issue (water pump leak) on my bike when I first got it. There was oil in this location when I took it in for its first service and a bead of oil on that bolt head as shown in the picture but after cleaning up all the oil, it has not come back. I suspect that it was just oil that flung off the chain. It was a brand new bike and chains are often lubricated with gear oil which can fling off onto the back of the engine casing and leak down. Have you put a new chain on recently or had the bike in at the shop? They may have lubed the chain with oil and this is what you are seeing.

Don't give the man false holes
That is clearly an engine oil drop.

I just got my CB650R 2021 with 8k km (I'm from Philippines and we use KM 😅) mileage and when I got the bike I didn't notice any leak whatsoever. Got it around 500km from home and I just drove it to check if there would be problems on long trips and the trip was great. Never had any issues but upon further inspection when I got home, I immediately noticed the moist crank case. Checked it and it was oil and degreased it and it's still leaking. I thought the oil filter was loose that's why it's weeping but even after tightening the oil filter, it's still the same. Changed the oil and the oil filter with no luck. I've read on Facebook groups that the O Ring was the common issue so I ordered one hopefully it fixes it, if not I'll be ordering a new water pump for it.
