Man this bike is quick and easy to service!
After sukkelling with the magneto cover - the biggest job was taking the seat and tank off, and checking the valve clearances. They were in spec (20000km).
The plugs (x2

) was easy and changing the oil even easier!
Total cost:
2 x plugs R235
4L Shell Advance R308
Oil filter R45
R588now it just needs a chain and sprockets.
Had a nervous moment when I realized theres 2 plug wires and couldn't remember which one came where then decided it's the same piston so can't be that important!
