clack when shifting into 3rd gear
 

At 0:22 of the below video you can hear what I mean

Many people have reported the same, on T�n�r�s as well as on Rs (we don't have the X here). Is it something to worry about ? My bike is brand new, by the way.

I think mine is the same...if not I'll write back after I'm out on it again...

:)

Seing the video, that clack brought a sense of familiarity I must say!
Hopefully someone can tell us if it's anything to worry about. Damn you for bringing it up, now I'll be listening for it every time I'm out driving :D

Took mine for a ride today...32c sunny so I thought I'd profit from it...

I paid attention to my gear change to find that it was not as noisy as I had remembered...

This might have something to do with the fact I now run 10w50 fully synthetic oil in the engine??

Hey guys mine was EXACTLY the same from new and I notified the dealer as I thought that we would need a gearbox strip. Mine was a noisy 4th gear. Anyway after about 5000 km the noise went away and Martin told me that often they need to be run in and that so far they have NEVER had to strip a gear box on a 660, neither MT03 nor XTs.

So dont worry you should be ok!!!

I'm just back in from another ride out...I paid special attention this time...yip there's a slight clunk but not that noticeable...my moto has 5000kms on it so I think it'll lessen as you put more klicks on it...maybe an oil change will assist at the same time?

:)

Thanks guys, now I feel better about this. Let's wait a while then. It runs on Motul 5100 , if it doesn't improve I'll try fully synthetic.

Sorry to through a spanner in the works, but my XTZ doesn't do it changing up to third and never has!? The sound reminds me of selecting first on a cold day, with a cold motor. Having said that I wouldn't worry about yours particularly, I'd wait to make a judgement when its fully broken in and, not just the engine, the gearbox and particularly the clutch plates too. In fact, have you checked the clutch adjustment? Dealers don't always get it right when they assemble everything out the crate.

The clutch free play is ok, in fact i just recently oiled the cable, so it's nice and smooth. I'll hang on to the break-in idea, but if it doesn't get better soon i'll just take a look at the disks, maybe they aren't properly assembled. I remember my old XT 600 had a similar problem and it went away after i changed the disks. Anyway, here in our local '66 forum this noise is not a rare thing. Oh and I'm sorry, Tacomodo ;)!

Heard the noise but with-out riding it hard to diagnose...my xt660x has a third gear issue but mine is jumping out of gear under load,gearbox now apart and the 3rd gear pinion meshing with 4th gear pinion is worn but to replace the gears from yamaha australia is about

Good that you bring this up, i've come across quite a few reports of trouble with the third gear, even in some cases it breaking and causing massive damage. The french Motomagazine reported just such a problem during their 50000 km test of a XTX. It has been suggested this could be caused by shifting into 3rd at too low speed and then throttling up hard. I hope the clack noise isn't related to this, but could it be a warning sign ? Not likely in my case anyway, since I'm old and rather slow.

hi for this third gear issue take a look at my gearbox thread i had contacted KEV about..this is what happens when you change up gear with-out using the clutch,im lucky it never broke up inside or it could of been a nasty mess,but to repair this im looking at over $1000 AUS (parts are a lot cheaper in uk) and i will fix it myself and for that money ive found a second hand engine..so another engine is going in

It broke inside to two guys here in the forum, a total mess. One of their mechanics advised to beware of stressing the third gear. I don't have access priviledges, unfortunately.

I have the noise on mine changing down to 3rd for slower corners/junctions. It seems to be at around 20-26mph but at slower speeds it does not do it so much. Annoying!

I also find that a little pressure on the gear selector just before i pull the clutch quietens it down. One smooth motion clutch an selector together.

My XTR has kind of noise when I put from 4th gear down to 3th and let it enginebrake. Never happens with the other gears. No problem yet that gears fall out under gasrespons.

The same here with my XT660X when shifting 2e to 3e gear.
But when i preload the shifter and change gear at about 50km/h (and above) the clack is gone and shifting like a hot knife through butter...:-)
Seems to have a sweetspot i.m.o.
