Spark Plugs

I had my local NAPA order me in some spark plugs for various motorcycles. The little Honda 50s use the C7HSA while the Bridgestone and Yamaha use the B7HS and B8HS.

The little Yamaha is actually rocking a B9HS, which is a colder plug guys use for all out racing the little YSR50 bikes. I've never noticed any issues with the colder plug, but figured I might as well replace it with the proper heat range plug, since I'm typically just putting around town.
