spark plug question
Posted: Wed Sep 17, 2014 11:30 am
I pulled the spark plug out last night and the previous owner was using the NGK BPR4HS(cold climate) instead of the NGK BPR6HS(standard) plug. I live in Chicago and will only ride the scooter in the summer. I need to buy a new spark plug but not sure if there's a huge difference in using the BPR4HS vs BPR6HS? Any info is appreciate.
Thanks
