AND FINALLY I CAN GET ON WITH rebuilding the top half of the ancient 125’s engine. Not too much of a challenge, you might think, for someone notionally familiar with smaller Yamaha. I’d normally agree with that sentiment but yet again I was flummoxed by both my own parts storage system and some supposed previous purchases. New base gaskets courtesy of Alasdair Cowan of YDS Parts got the show on the road. Everyone has their own particular MO for seating these card gaskets but I’m happy with giving them a light greasing on both surfaces. If there’s no oilways and the like going through them, I can see no legitimate reason to apply any sealing compounds. The system’s worked for me for decades so it must be viable, surely?
