My R6 has a prematurely worn 2nd gear dog and had only done 20,000k's.
The symptoms are that the transmission briefly disengages whilst under power in second gear. This feels as though the bike is briefly loosing traction or a hiccup in power delivery.
The bike has had a good life and is overserviced - never raced etc.
Yamaha won't fix it under warranty claiming 'normal wear' and I am probably abusing the bike or don't know how to change gears!!!.
I say bull**** .
Yamaha mentioned that this problem is starting to appear a bit now on the R6 model only (interesting that it is only us R6 riders who don't know how to change gears eh...). They have stopped fixing this problem now under warranty because it is happening too often!!!. The have examined the worn gear and say it is manufactured to the design spec, so it is not their fault. !
I say: Then the design spec is wrong...
It is unreasonable to expect this much wear so early on.
I suspect Yamaha don't want to admit that they have a design flaw with their baby and it is hard to prove otherwise - me not being a mechanical engineer.
Anyone else have or heard of this problem?
Given that the bike has only been out a few years, the problem may not have had much of chance to show up yet, but i predict it will soon appear in great numbers...
Yamaha have indicated it seems to happen mostly after 15000kms.
Since first noticing the symptom at 20,000k's, it took me a further 12 months and 10000k's to work out what the problem was. I have spent a small fortune replacing chains and sprockets and getting the carbies cleaned etc only to realise one day that it only happened in 2nd gear. Then I was straight on the blower to Yamaha who have secretly known about it all along.
So if anyone else is having this issue, let me know. The more people who have it, the less likely it is that I just can't change gears properly, and maybe we can force Yamaha to do something about it.
p.s. I really do know how to change gears properly
