|Adjusting the valves from the 500cc Piaggio MASTER|
engine is quite easy and takes less than 10 minutes...
,,,if they were easy to reach....
But getting there takes some time.
First put her on the center stand and remove the 2 screws what hold the seat.
Remove the seat
Remove the footrests
Remove the silver transmission plastic cap (and her 4 screws)
Remove the 2 screws in the gas flap
|remove the gas cap - remove the gas spill guard - replace the gas cap|
|remove the battery and the screw what holds the battery holder then carefully pull the whole thing out|
|remove the 4 screws frrom the ECU|
|disconnect the ECU|
|look at the mess and move the cables etc. out of the way|
|remove the 3 screws - twist the connector to reach the left screw|
|remember to reconnect the grounding wire later (here with screw)|
|the valve lid is waiting for a 10mm socket and is just hand tight screwed|
|remove the service openings|
|you need to unscrew the hose holder and wonder about the placement of the support for it|
|loosen the 6 screws (some might held in place by the rubber seal) and carefully fiddle the lid out|
|you reached the valves|
|remove the screwed in plastic plug (don´t worry most thicker screwdrivers etc. will do)|
|rotate the engine slowly counter clock wise with the driving pulley nut until alignment|
|through the service opening you can also check the alignment for upper dead point|
|wiggle a bit on the metal cup between valve and screw to get it loose and here you want to put the feeler blade|
|you have 4 valves to service|
|use the 2 service openings for easy access to the lower valves|
|check how big the gap is (mine after 40000km was between 0,2 and 0,25 mm|
Now put it back together in reverse order and when you are tighten the valve lid do it a bit a time, hand tighten first and then in 2 steps final tighten the 6 screws.
Check if your bike is still running , if so - congratulations: you are now a junior mechanic first grade.
