Valve Clearance Measurement; Valve Clearance Adjustment - Triumph Speed Triple Service Manual

Valve Clearance Measurement
Note:
Valve clearance measurement must be
carried out with the engine cold.
1.
Remove the cam cover (see page 3-5).
2.
Remove the spark plugs to reduce compression
resistance when turning the engine.
3.
Select a high gear and, using the rear wheel, turn
the engine until a pair of camshaft lobes are
positioned pointing away from the valves.
4. Using feeler gauges, measure and record the
clearances for this pair of valves only.
5. Repeat the process until the valve clearances for
all valves have been checked.
NOTE:
0
If the measurement does not fall within the
specified range, adjustment must be
made.
Note:
The correct valve clearances are in the
range given.

corrected, wear could cause the valves to remain
partly open, which lowers performance, burns the
valves and valve seat and may cause serious
engine damage.
