Manual gearbox problems

I'm at 550 miles now and have the following issues with the manual gearbox
When the engine is cold on startup the gear selection is acceptable as the oil warms 1st to 2 nd is a pig and usually clunks loudly the gear selection is notchy beyond acceptable and sometimes but not very often it is silky smooth.

The dealer said the bike is filled with mineral oil for running in and is changed to fully synthetic at the first service hope this cures the faults

Any one else had this problem

I can't speak to the AT, but my VFR when new would be a bit clunky between downshifts in first and second and I'd occasionally 'miss'. After it was broken in a bit it was never an issue again.

Initially I thought it was my technique or lack of
I'm hoping all will be good after the first service

Nope, that sounds wrong. Mine has 1150km on it, so about 720 miles. I have the first service booked for tomorrow, and the shifts are still smooth. Yes, it takes a bit of pressure to shift and always has, but the shifts are smooth with no false neutrals.

Sounds to me like you have a problem.

Oh, I'm making sure the first oil change will be to mineral oil (Honda GN4) too, changing to synthetic at the first service is too soon - it needs a bit more time to bed in properly before switching to synth. I'll be changing the oil and filters at about 5000km with another gutful of mineral, then switching to synthetic at the 12000km service.

Check chain tension. Sometimes when a chain is too loose the gear change can suffer. Check also that there is not too much oil in the crankcase. Otherwise as suggested above, check things out again after the first oil change. Just for info I mentioned to Honda that I was considering fully synthetic. They advised against it.

Hi Fast Eddie,

I have not at any time experienced the probs you describe, I'm on ~2k miles now, the bike's gear changes have remained smooth throughout, you may have something to investigate there.
Griff's suggestion about chain tension is worth checking. As to deviating away from the Manu's oil recommendations, I would be very careful.
Hope you get it sorted.

Hi all

The chain was adjusted a couple of days ago by the dealers mechanic I did not notice any difference.

the oil choice is down to Honda uk and or the dealer ?

One other aspect I forgot to mention which was also mentioned on the other forum where a member has an occasional false neutral between 4th and 5th is to adjust the slack in the clutch lever. If there is too much play in the lever the clutch sometimes does not disengage properly.


Otherwise like others I have found the gearbox on this bike to be very good with slick changes throughout.

I had mine jump out of 6th on the freeway. Hit neutral which I have never experienced on any other bike.Only happened once so maybe I didn't engage it properly. Haven't ridden since hopefully not an issue. Other than that gearbox very smooth.

Sometimes the relationship between the boot and the gear change pedal is not good. As such some adjustment of the pedal might be required. On the other side of the bike I was locking up the rear brake too frequently and that is something I do not normally do. I adjusted the lever down a little and problem solved.


Get a trusted rider to ride the bike and see if they have the same problem with it. If not, then you need to do some adjustment of technique or pedals.
