ThereÊis a good chance that somethingÊisÊgoing on internally with the engine. It is best to have a mechanic perform a diagnostic to determine if the rocker does in fact need to be replaced.

there is no adjustment
The Honda VT1100 has hydraulic adjusters, not hydraulic lifters. No adjustment is necessary. There is an adjuster for each rocker arm, but it is hydraulic - there is no adjustment possible except by varying the oil pressure. The rocker arm in the engine is fixed, so the lash is not taken out like it is on a push rod engine with hydraulic lifters. The valves cannot be adjusted but the valve lash can be set by adding or removing shims. However, the engine has to be dissasembled for this.
With the engine at operating temperature back off the rocker arm until it slightly clatters. Tighten it down slowly until the valve is quiet and then tighten it 3/4 of a turn more.jd
