Sixth Gear Failure on 62 Reg CBF1000 with only 9k on clock
« on: 14 January, 2019, 04:51:29 PM »
Has anyone else suffered from a broken tooth on sixth gear?

My bike has had less than 9k on the clock and been regularly serviced. I had to take my bike off the road for over two years as I was told that it would cost over £1700.00 to investigate and extra to fix dependent upon what was found as the whole gearbox had to be stripped.

Is the broken tooth your theory or the mechanics?

Is there strange noise involved in the operation of the gearbox of engine?

If all other gears work what happens if you put it in double stand and go though the gears with the engine running at idle. could we get a video ?

is your bike first hand or second third etc.
Has it had any work done in your knowledge?

by  regularly serviced  at 9000 you propably all you have done so far is oil changes . When was the last one done?

Nice looking engine that is - make someone's A look like a nice mkII too.
Isn't 6th the least likely to get chipped? and if it is C6 (peg) then surely 5th would be noisy too.
I'm not convinced a serviced (yes, prob just oil ...) Honda anything at 9k will have a broken broken box unless you know what happend (and you'd know).
Best see what is what; you should be able to remove the gearbox cassette with everything in situ (well, removing certain parts for access).
Only do it right - no bodging please.   Keeper of the failed stator list.   John.
