Need insight in sparkplugs
So all I have as far as modifications go are the 2bros slip on, 1 shim on both needles.
The guy at the shop said my bike would run better with a hotter soarkplug. He was saying to get the Ngk cr7hsa. My stock ones are cr8hsa. Any thoughts on this? |

Do a search for Iridium Spark Plugs first.

A hotter plug is used when you are running lower RPMs and loads than "normal". Chances are that's not you. I don't know anyone that has gone to a hotter plug, but I have suggested it to the high MPG guys before. Generally an engine that is making significantly more power than stock runs a colder plug - turbo, nitrous, bored/stroked/higher compression, etc. Most of the time the standard heat range is the best compromise. |

Stick with the 2 dollar ones. Also wouldn't you need bigger main jets with a custom exhaust?
