Final drive oil 1st service

[Dudders]

Well the owners handbook states every 3 years but I don't subscribe to that. Very easy to change and I'm glad I did,very grey/metallic.
This cannot be a good thing.
I'll be changing this one each and every. If it gives you confidence it can't be wrong.
I intend to try a 10w40 semi(elf) in the engine. It claims to be able to vary it's viscosity. What I do know is that 1st to 3rd gear changes aren't the nicest,4th to 6th are fine but hopefully whole box will become sweeter.
Lovely bike though.

Gearchanges have improved as expected however downchanges 3-1 will always be 'agricultural' I suspect and need a blip of throttle.
On a light throttle I am getting 60 mpg+ up to legal limit👍🏻

Hi Dudders,
Is this ELF Moto4 10w40 you are using (10w30 is recommended by Honda!) ?. If your bike has very low mileage, shifting will improve as the miles rack up.
I think you should get a medal or star if you get 60mpg+ from a CT, possibly the first on this forum!
I agree with you about the rear Diff, It is so easy to change it can be done every time with the engine oil. A litre of 80w will do 5 changes.

Cheers
Tom

Hi Tom,
Yes it's a fairly new one and this was it's 1st service. I'm an old retired motorsport engineer and I'm prepared to forfeit warranty so that it's only me working on my bike. I can take as long as I like and get every task absolutely spot on.Honda wouldn't recommend the oil you're quite right but I'm not a 'do as I do' type,I've no time for them.
55-65 mph is where I usually am I should add with a little 70+ to pass traffic. I really am getting those mpg figures according to the dash and my arithmetic. I used to manage same on VFR1200 too but fully expect the numbers to plummet if you hurry this heavyweight along.
With a lot of redundant unopened MotoGuzzi gear oils on the shelf it's nice to be using it up finally albeit it @ 200 ml a pop

Ta,
Dudders.

Gear changing definitely will improve over the time - can see positive changes now, having about 6k miles on the clock. 
Regarding oils - changing shaft oil once a year, easy job, 1l bottle should last for 5 changes.
Loads of forum people is using 10W/40 engine oil, personally decided use genuine Honda 10W/30 one for the first oil change, this year will try Motul 5100 10W/30 semi-synthetic.
60+ MPG, bloody hell such a figure. I'm getting about 50 mpg riding quite slow.

Honda states both, 30 and 40 and it depends a bit on where you live.
In a warm climate i would advice the 10W40 and in a colder climate the 10W30.

@OP, maybe change the topictitle because it's more about the engine oil instead of the final drive.

[Dudders]

Agree with you Ray but that'd attract the oil 'experts' that all forums seem to be plagued with.

Ha ha Dudders, never a truer word spoken.
Best of luck with your CT.
