Rear shock spring

It is time to rebuild the rear shock so we can install the engine in the chassis. Just back from Christopher Markley today is our stock MeCur spring powder coated black to match the color the factory would have produced for this bike originally. It cost $12.50 for the paint and it looks great (there is some dust on it in this photo, but the paint is perfect)!

We will use the same motorcycle shock oil in the rear shock as we did in the front. It may help stiffen the ride a small amount and help cut down on drifting.

I was so dead-set on using a performance spring, like TaffSpeed, and I am glad I learned that drifting is not entirely due to the shock.

Lesson learned:One side on the shock was NOT powder coated and I asked Christopher why that was the case. Here is the answer I got:

"You beat me to the e-mail. Put those ends facing down. When powder coating,
you can suspend the part on wires or let it stand on its own if it has a
flat surface. Regardless, wherever it touches, no powder. Seems on the
springs that shortly after installation, the powder or paint if you use
paint will quickly wear away as the spring seat grinds around against the
shock spring support. So I opted to not suspend the parts on wires, since
the suspension points would have been on a visible surface of the spring.
This way, they look pretty and the part without powder would have lost its
coating anyway in use. If you're worried about it, a smear of thick axle
grease where the springs meet the shock could postpone corrosion, but it is
inevitable at those mating points eventually."
