Decades have passed since those legendary top-speed days, and you hardly see them anymore.
A Deco-mainte request came in.
First, as always, we check the chain area. I think it’s about time for a replacement.
We use the shop rags to their absolute limit—until they can’t absorb any more dirt.
Just wiping parts when you remove them makes a real difference in how long they last.
The rear axle is within spec—no issues.
We also adjusted the wheel bearings.
Radial tires—reliable and stable. *Bias tires will feel a bit squirrelly by comparison.
The rear caliper is about what you’d expect for the year. The piston action is a bit stiff. Keep an eye on it going forward.
The chain case bolt holes were stripped, so we helicoiled them.
*With box-shaped (bag-type) parts, a helicoil with a tang will leave the tang inside, so you can’t use that style.
Moving to the front. Speedometer cables rust and get gummy more often than you’d think. A good cleaning and lubrication helps them last longer.
Fork. Bottom gets cleaned and lubricated. Top gets rust protection.
Upside-down forks will run reliably for a huge distance and many years if you keep them well lubricated and rust-protected.
Clean any areas you can reach while parts are off.
Keep them clean and rust-protected, and they’ll stay in good shape for a long time.
The front axle was also within spec.
The wheel bearings look good.
We gave them a quick clean while they were off.
The front caliper is about right for the year too. Piston action is a bit stiff.
