gy6 75cc spark plugs...
Ok so heres the thing.
First i had Denso spark plug in my scooter for about a year before it died. Than i bought NGK spark plug and it was working only for 2 months, than i bought another NGK spark plug and it was only working for 2 months again.
Every single spark plug was doing the same when it died: yesterday scooter started, today it wont, tommorow it will start again :S
And the problem is that spark is going from center lead to circle around it instead of going to upper lead.
Was i just unlucky and get old spark plugs at the shop or something or is my scooter wrecking the spark plugs?
Thanks!
