Tinto senor? "Por favor… muchas gracias" I could sure use a cuppa. It is one o'clock in the afternoon and it's pouring rain. Shit weather, just when I have to do some work on the bike.
Half under a shed, on my slippers, I start working on one side of the motor anyway. At 3 o'clock that side is stripped and it is getting dry so I can finally work on the other side to dismantle the water pump, oil filter, lid and clutch. On the crankshaft there is a really big screw. I need spanner 36. I don't have it with me but when I try to get it loose I see that Japanese John didn't have one in his toolbox either. Just screwed it on with his tiny hand and give a big slap on the security plate, that's that and who ever needs to get it loose has a problem. This way it is not surprising that the Yamaha is shaking and makes strange noises. There is a double cogwheel, one with a shock absorber to drive the balance shaft and one to get the clutch plate holder going. The square pin is very widened. I turn the pin and borrow a terrible big tool, put the screw back on it's place, secure it and put everything back together.
At 8 o'clock in the evening big happy plops come out of the 100 mm bearing and the Yamaha sounds like never before. It whistles a little, but I just whistle back and it's as good as new, really!
I had already removed the clutch lid before because of the shaking but couldn't find anything, didn't see anything either. Put everything back in place. I thought. But didn't. A little sloppy. If I had driven a little further I would have had to replace the crankshaft anyway. Pinhole broken. Fortunately a pin is always quite soft with regard to the hardened crankshaft.
In short: Let's step on the gas again! Indestructible such a Yamaha!!
