so i got my new NGK spark plug caps this morning and ive just fitted them. good thing is i didnt get a shock when i touched the leads but it still makes the funny popping noise when i get water or WD40 on spark plug no 3. the sound is like blowing bubbles in water. when i tilt the bike to the right to drain the wd40 ive sprayed there it still makes the noise slightly. could this be a problem with the spark plug not in the right place? one way i did manage to stop the noise a bit was to pull the rubber boot at the bottom of the spark plug cap down a bit then fit the cap on the spak plug.
