Gearbox oil change
Don’t be mean, give your gag bike a fresh dose of light gearbox oil every 500 miles or six months, whichever comes first. After all it has to work hard with you on it, you big lump.
Spark plug change
Easiest done with fairing lowers off. Plug is NGK BR7HS (BR8HS for the 80)
Top-end overhauls really don’t get much simpler than on these air-cooled two-stroke singles. It’s wise to retorque everything once the bike has been properly warmed-up then allowed to cool. 50 exhaust clamp is screw-on, 80 bolt-on.
Equip yourself with a clutch holder and flywheel puller. If you need a crank rebuild then this is the only thing that will hold you up as it’s a specialist job.
Fork oil change
Take the legs out and give them a proper strip and clean when changing oil. Twin spring conversion from teamcalamari.com
Give the front caliper a good clean and a little smear of silicon grease on the sliding pins. Check the condition of the braking surface in the rear drum.
