I feel your pain! At times it is one step back to get two forward. And the worst part is if you cause that your self. But it is easy to be clever afterwards... I once bought an Audi 100 (the old original ones that won Rally Champs as a Quattro). I spent hours reading up re repairs (had a 3 gear auto that did not shift in to 3'rd, but still easily did the speed limits...) and took out the gearbox to replace it with a recond one. After many hours I had the job done. That auto only lasted 10 hours before the reverse died... so out it came again. With both now in pieces I made one out of the good bits. And it worked!!Broke the outter clutch hub trying to torque the crank nut to the correct spec. Doesn’t quite add up right? Another genius move. That’s another 330 down the drain. Gotta wait til my next paycheck too.
Tried to replace the water pump bearing cuz it felt gritty and now the new one is almost all the way in. Just another mm to go but it won’t budge. Guess I didn’t heat the recess enough. Can’t pull it out without ruining the bearing and I can’t heat the case without melting the crank seal right next to it.
After this clutch hub it’ll be nearly 1500 on this reabuild and almost a year of not being able to ride. I’m so fed up with this. Every time I work on it something else goes wrong and I’m out even more money and the time it takes to ship the parts here.
My point is: I was now an expert having info on a redundant gearbox for a car that there is probably less than 100 in my country (New Zealand) and I have seen none other on the road! It would have costed me US$ 500 to have the original one sorted by an auto gearbox specialist (I found out later...). So that redundant info is now filling up my head together with electronic engineering from the 70's, PCB drilling machines servicing (that used punch tape "data storage")... hmmm where was I going with this... not sure. :grin2:
I have a complete clutch hub from a 2012 125sx that is the same as yours that you could have for US$150 including postage. We dismantled the bike and sold most of the bits. The clutch hub was to be a spare, but now when I have fitted a Hinson to our 2016 bike it is surplus. Has had approx 30 hours of use and has minor marks from the plates but noting that will cause issues.
Let me know if you are interested. (I don't have the hub for sale anywhere as I was happy having it on my shelf for a rainy day).
