Got a set of plugs this week at the bike shop and when I went to put them in today I noticed they were CR8E instead of CR9E. I went ahead and put them in anyway even though I know it's a slightly hotter plug. Well...my bike seems to start better and run a little smoother. Temperature guage didn't seem to change any from the 9's. Is there that much difference between plugs?
Sparkplug difference?
