Gearbox Updates?
 
Hi guys just wondering if anything happened from this thread. My 2009 xtz (26k)has just lost 3rd (unless you smash it in and out).I just nursed it home today so only had to ride about 8miles on it. My question is that as a mechanical novice on bikes, how expensive a fix are we talking? I have a 4000mile bike tour planned in 4 weeks and am wondering if this bike will not be taking me there? Typical!!!

I have just stumbled across this, mostly because I was never looking for issues, and checked my log book to see m311e0007925. Bike is 09 and 8000miles, guess I'll have to keep an ear out :hb:

gearbox update
 
so the bike is in intensive care... third gear failed and bounced around a bit taking a few bits with it....all in about �1000 fix. i leave for a Europe tour on the 2nd sept to visit my dads grave in Bulgaria, they are hoping to get it back to me before so i can get some mileage in to make sure its ok. going to be tight. fingers crossed itll be ok on the trip.........

I'm sorry I read this post now..... My bike is a 2009 and the engine number falls in that range!!! So what should I be looking out for?

Gotta say PanosP my engine was also in that batch and blew it's 3rd gear at 46,000 Km, (some go with less), in December 2017, on a motorway joining sliproad. There are no warning signs, it just goes. Some have said, in the past, that the 'stopper arm' or its spring may have contributed to the failures. I changed mine as a precaution for brand new Yamaha parts in the hope I'd be OK. It was a simple job and took a couple of hours. The parts were 40 euros. It didn't stop the inevitable. In fact the gearbox shattered a few thousand K's later.

It's easier to change the entire engine than strip out a busted one and cleanse it from the shrapnel which will just destruct a repaired engine. I bought a replacement motor that was in an Aprilia Pegaso. The same motor is also in MZ's.

Yamaha have disowned the problem and not every engine in that batch has failed but it is a game of Russian Roulette, especially if you're on a massive tour.

sorry buddy!

A replacement engine seems to be best choice

Sorry, as far as I know MZ only used the old 660 engine with 5 valves. Won't fit !

if these 5 valve motors won't fit, i guess you could always make it fit by welding new brackets? don't thing they will all differ, especially the one thrue the swingarm? that last one will line the engine nicely out.
when the needs comes to make one fit, it'll work.
