I'm sorry to hear about the failure of your YSS shock.
I have had a YSS on my 170i for about 10K miles. It can be adjusted to provide 10mm of static sag that really helps the ride and performance overall. I've had YSS shocks on other bikes and find them to be a quality piece at a bargain price.

Babblefish. Agreed, I think combustion gasses leaking passed the rings was the issue with oil darkening. The new rings/piston/cylinder are breaking in well and I look forward to being able to ride the scoot' a bit faster soon. I can feel the extra power even with partial throttle during break in.

And check that the rotor is straight. When we don't change our brake fluid enough, and when our bikes are old, the caliper pistons tend to not go back into the cylinders and create more than usual drag.

I'm in the thermal business. The temperatures I measured were while running and with no motion.
I think a real heat exchanger designed like a radiator would be great.
Nice lateral thinking regarding using light weights that make the engine spin to a higher RPM and provide better cooling!

I've measured the temperature of the heat exchanger and oil in/out and it's not producing much cooling. The surface area of the exchanger is pretty small and the mass is high, therefore responds slowly to changing oil temperatures.

Removing bodywork on scoot's is generally not fun. It's quite easy to damage the little clips and straps. I find the Yamaha TMAX bodywork to be of good quality and removal is above average in ease. Vespa/Piaggio bodywork is the most difficult and easily broken, from my experience.
