I replaced plug because it has been 3 years since i have. I figured it was time.
Had no problems. plug looked toasty and worn so "what the heck. a spark plug is a spark plug, right?" WRONG
I went to auto
parts store and did not have my usual NGK brand I use. I have had good performance out of denso plugs but did not have those either.
So I have to choose the dreaded champion brand.
My trike used to start first pull. Now, I have to use choke every time.
Seems like a weaker spark also and gap is spec. Seems there is some power loss too. Champion plugs are POS and learned this 25 years ago, but here I am, glutton for punishment. American plug in a jap bike. Not the best choice.
DO NOT USE CHAMPION PLUGS IN ANYTHING!
VERY TRUE
NGK is best
