HONDA CB360 / CL360 / CJ360 Answers
Recommended oil viscosity for general riding and all temperatures is: SAE 10W-40.
We've also had success running diesel truck oil (Shell Rotella, Chevron Delo, Mobil Delvac) at 15W-40 viscosity. Diesel oil has the bonus of extra detergent additives as well as zinc which older engines need. Synthetic oils are are not recommended as they will cause your clutch to slip. We recommend adding 2-3oz. of Zinc additive with every oil change.
When changing oil: 1.5L (1.6qt.)
When separating the crankcase: 2.0L (2.1qt.)
Always confirm oil level with the dipstick.
Every 1,500 miles / 2,400 km.
We recommend premium (92+ octane) fuel; if it can be found non-ethanol fuel as well.
CB360: 2.7 U.S. gal., 11.0 lit., 2.2 Imp. gal.
CL360: 2.4 U.S. gal., 9.0 lit., 2.0 Imp. gal.

Front Tire: 18-100/90 (modern sizing) / 3.00-18 (old sizing)
Rear Tire: 18-110/90 (modern sizing) / 3.50-18 (old sizing)
Front Tire Pressure: 26 psi / 1.8 kg/sq. cm
Rear Tire Pressure: 28 psi / 2.0 kg/sq. cm
Front and Rear tire inner tube sizes: 18" x 3.25" - 4"
UPDATE: As of January 2020, NGK has discontinued the B8ES and
superseded with the BR8ES. The BR8ES is a resistor plug, which is
designed to reduce electromagnetic interference of ignition systems for
things like radios and phones while used in automotive applications. It
is the new replacement plug for our vintage Honda motorcycles and
performs just like the older B8ES spark plug. More info about resistor
plugs can be found on the NGK FAQ page.
Gap specification: 0.7 - 0.8 mm (0.028 - 0.032 in.)
The main fuse is a 15A fuse and the sub-fuses are 7A fuses.
Standard (non O-ring) clip type master link drive chain with a 530 pitch will work.
Watch our YouTube video on how to count the links in your chain for the appropriate length.
Lubrication and inspection of the drive chain should be happening every 500 miles / 800 km.
Maximum slackness when measured by moving the drive chain vertically is 10 to 20mm (0.4 to 0.8 inches).

Factory spec on the fork oil is 135 - 140cc (4.6 - 4.7 ozs.) of premium quality ATF (automatic transmission fluid), however we recommend a 10W (light rider) to 15W (heavy rider) motorcycle fork oil. ATF is approximately 5W and replacing it with a heavier weight oil will stiffen up your front end.
Every 5,000 miles / 8,000 km or once a year, whichever comes first.
