Aprilia RS 125 How to test spark plug with multimeter to see if is it is good or bad
Its a very easy but useful test to make sure your spark plug is ok , you may need to clean the electrode to ensure you get a good reading but all you then have to do is set meter to read ohms and measure from the spark plug cap end to the electrode tip , and then from end to body to make sure no leakage to earth.
Buy RS125 NGK spark plugs here i always use them

i have an Aprilia rs 125 2001 plate and starts and stops , i checked for a spark and i am only getting multiple sparks . what would be the problem
A)
hi , its hard to help when i d not know full story , is it a new bike that is never started properly or is just started happening ?
if your sure its spark then try a new plug first obviously then test coil , cdi etc .
test coil on input side see if its getting 12v to it .
starting then stopping could be fuel , have you cleaned carb out and cleaned jets out
Spark/Compression/Fuel/Air/Timing
You need all the above to get the engine to run.
Remove the plug, reconnect it to the HT lead, hold it on the cylinder whilst turning the engine over and you should see a spark.
Whilst plug is out do a compression test.
Check fuel is fresh and getting to the carb.
Check air filter is clean.
Unlikely to be timing but rs125s have been known to snap there own woodruff keys
Prob spark problem - duff plug , cap, ht lead, coil - prob not CDI but never know , timing slipped with woodruff key .
Try the obvious first and reply with findings!
