Hi,
This summer i was riding my '01 shee With denso plugs and it did great, till one
day i thaught, i should replace my plugs because they were in there for a while. So i did i changed them with brand new NGK BR8ES, those did fine for 2 days, then they just died all of a sudden, i put back the old ones and they also died after a day. ( i know sometimes i dont let it warm up so good, buts it was more than 90 degrees outside) ::
my question is, what could have caused this to happen?
