Hello, I am the proud owner of a 2014 CB650FA (the 35kw version), it has 36k kms or around 22k miles on the odo, and it started presenting quite a loud ticking noise that is most noticeable on the left side of the engine. The oil was changed 2000 kms ago and I was planning on changing the spark...

Sorry if I am beating a dead horse on this, but after reading through all the threads on the frame sliders, but it's not clear to me what the safer option is. Seems like a lot of people are saying there is a risk of them cracking the engine mounts on this bike. I understand to avoid the single...

a lot of bikes have that problem but in their case they think it because they changed the exahust.. its not the case. it a bug from honda itself. the way they deal with different with high changes. it will happend to everyone who ride 500 meters or more above sea level. the easy case you will...

My bike has recently developed a rattling sound coming from top/right of the engine (cam sprocket side). I’ve tried replacing the CCT with both another tensioner and a manual one. I’ve also replaced the cam chain and guides with used ones from a 15k mile bike. The sound is still there. The...

Hi everyone, I need some help diagnosing a strange rattling/knocking sound coming from my engine. I'm worried it might be something serious, so I wanted to get your opinions before tearing it down. Here are the bike details: - Model: Honda [CB650F / CBR650F] - Year: 2016 - Mileage: 49,000 The...

I have a 2016 CBR650F which has done 30000km. The bike is completely stock. Spark plugs were replaced at 20000km. The bike acts weird when the engine is cold. There is a bogging that is felt at 2000 RPM if I rapidly increase the throttle as if it's running out of fuel. If it slowly increase the...

Hi. I have a 2024 CBR650R and I looking to buy a good oil for my annual service. I was thinking about Motul 7100 10W30, but is there anything better on the market? Any recommendations? Thanks.

Hi everyone, I'm hoping you guys can help me figure out a weird issue with my 2016 CBR650F. It has about 48,500 km (around 30,000 miles). For the past few weeks, I had a strange issue. Sometimes when I'd start the bike, the check engine light would stay on. But all I had to do was shut the...

Hi, any take on this? Yamaha patents 'fake' engine for electric motorcycles

I recently bought a new 2025 CBR650R with the e-clutch. Everything was fine at first, but just a couple of days later—after riding about 520 km—I noticed the engine warning light came on. I checked the error code by counting the blinks in diagnostic mode, and it showed 13 long and 3 short...

So I’ve had my cbr650f for a few months now and have recently started getting a flashing engine light (flashes twice every 10 seconds in neutral and is constant when in gear and driving) and bad rev symptoms at around 2.5k rpms it sticks there until I brake or pull in the clutch a certain...

Hey all, I have recently engine swapped my 2016 CBR650F due to the engine blowing itself up. Refer to my previous posts about what I did. I have successfully put a 2015 CBR650F engine in, due to the 2021 CBR650R engine missing the hole for the VS sensor. After installed it, I followed the...

Recently, I had to swap my exhaust back to the stock one and then reinstall the custom setup. After doing that, I started hearing some engine noises. When cold and idling, there was a clicking sound, and while driving, it resembled a sewing machine. After some research, I found that the issue...

Hey guys, I just noticed this leak near the engine and I couldn't trace it. Any ideas where it might be coming from ? Thanks

I went on a roadtrip in the south of France last weekend with a friend, had a little (too much) fun on the bends, and lost grip on a right-hand bend. My front wheel exploded, the front brake lever, the spider and I fucked up the right side fairings, the brake pedal and the exhaust are bent...

Hi All, I've recently stripped my CB650F 2018 engine down and found scoring on a couple cylinders and gouges on their pistons. Looking like it will be too expensive for any shop to rebuild it respective to its worth. I've found a CBR650F engine of the same year and was wondering if the engine...

My CBR 650 is making a tapping sound and the engine light is blinking when idling. When I go riding, the engine light stays on but does not blink and the tapping sound speeds up. I did some quick research and saw that the code was related to a faulty O2 sensor. When I took a look at it, the...

Hi, I was being a bit of an idiot and ran the bike for way too long without checking or replacing the oil. At 6,700 miles I had a rod go through the engine case as you can see pictured below. Now I'm looking for a replacement engine to do a swap and coming up kind of empty. Does anyone know of...
