All 650Fs Honda CB650F upgrade/maintenance log

[enshiu]

Hi, so after buying my second hand commuter with 81k mls on the clock.

I have some small issues.

To do:

- Rattle at 4k at the clutch housing
- Main engine cam chain needs replacement
- white smoke at cold start and dissapears
- exhaust leak due age
- air filter?
- spark plugs
- brake hoses


Things done:

- fan fuse broke 02-04-2023
- throttle cable adjustment 02-04-2023
- oil change and filter at 130726km 02-04-2023
- rad cap changed 02-04-2023
- Headlight and rear licence plate light modded 04-04-2023

Just put a better bulb in, don't mess with the headlight itself - it's not worth it.

Do the air filter and spark plugs together... It's easy enough.

Cam chain and that knocking noise is more work! Could be a faulty tensioner. That's an easy fix so might be worth doing first.

Exhaust is easy if you want oem. The smoke might be steam and normal? If it clears I wouldn't worry about it unless you are losing coolant.

Yes will put a projector headlight bulb in

So, I modded my headlight and rear licence plate light:

Ok, so since no one else asked, I’m going to:

What‘s up with the huge ass wrap around handlebars? That is the weirdest thing I’ve seen in a long time, and seems dangerous as hell to me. Be interested to know more about them.

I call it anti drop bars. They use it here to beginner learners. If you drop the bike there is almost no damage to the bike.

All driving schools have these on their bike to minimise damage.

Ok, kind of what figured. I see there is a middle mounting point otherwise they’d put a lot of strain on the handlebars and they’d bend fairly easily depending on the bar. So you chose to run them? Kind of a “slider” thing I bet.

What they looked like in my head are something you’d use if you wanted to do crowd control, like in a zombie or Max Max futuristic style of movie, lol!!!

He mentioned on the gallery topic that this bike was a former learning school bike.
I presume there´s why all those protections. I would remove them...

So I got my air filter box cleaned and changed my spark plugs to iridium:

Exhaust leaks badly condensation:

Coolant check;

 

[Brammers]

The exhaust condensation leak is normal, there's an oem drain hole there for this purpose.

So I have washed my bike and looks less dirty:

 

[enshiu]

Akrapovic exhaust installed:

What a pita to get the old exhaust manifold bolts off at this high mileage, All bolts/studs are now greased with ceramic grease.

 

[enshiu]

What a pita to align those headers:

So I am getting the 4 hole db killer this time. Hopefully little quieter than a single hole.









some leak found:



oem exhaust gaskets.

 

[enshiu]

So I installed a oxygen sensor delete on my CB650F now.



Fully deleted it. O2 sensor blank oil drain plug installed.

 

[enshiu]

So I installed new brake pads and made some pictures:

 

[Brammers]

Why the manual cam chain tensioner if I may ask?

J

 

[enshiu]

The last owner put already a new one on oem still rattles?

 

[Brammers]

Are you positive it's the cct / cam chain that's rattling?

J

 

[enshiu]

yes, chain has never been replaced, honda recommend to replace after 100000km
