So I went to LORDCO in burnaby while I was grabbing a new magneto and expansion chamber.
I did some research and figured I may as well get a better quality spark plug while I'm upgrading my parts and correct me if I am wrong but the NGK b6hs or bp6hs or bpr6hs would all work right? or 4/5/6/7hs etc.
I came to the conclusion 6hs would be the best for general activity.
So now when I compare my chinese stock plug that came with the engine and the new NGK bpr6hs they do not seem the same.
Here is the picture comparison side by side. Is the slight difference in length okay?
How come it is slighty different when these forums cearly say it is the best replacement plug?
