I just found out that that there is a such thing as a hot or cold plug. I run what the book says B8ES. I recently got a new 10 pack that have an R (I think) on it. I haven't tried them yet. My cousin has a B9ES and said its a hot plug.... Can you guys explain the difference and what works better in different conditions. My bike runs great and starts first kick 95% of the time unless its super cold then like 5 kicks with choke out.... Any info will help...
