Checking the valve clearance
To remove the head cover:
- Remove the rear shock absorber.
- Remove the helmet compartment.
- Lift the body.
- Remove the clamp of the H.V. wire
To check valve clearance, centre the reference
marks of the timing system.
Use a feeler gauge to check that the clearance
between the valve and the set screw corresponds
with the indicated values. When the valve clear-
ance values, intake and exhaust respectively, are
different from the ones indicated below, adjust
them by loosening the lock nut and operating on
the corresponding set screw, as shown in the fig-
ure.

Level check
Proceed as follows:
- Rest the vehicle on its centre stand with the han-
dlebars perfectly horizontal;
- Check the level of liquid with the related warning
light « A ».
A certain lowering of the level is caused by wear
on the brake pads.
