Spark plugs

[Dfurgi]

Hey is there a way to tell my listeneing to the bike if all the spark plugs are firing?

Spray water on the down pipes from the headers.

steves, do you do that one pipe at a time? And what exactly should you hear if they are firing correctly or incorrectly? And do the headers need to be cold?

[steves]

One pipe at a time. If the liquid sizzles off, it's hot. If it doesn't, it's cold.

Check out Carbs101 in the wiki.

I prefer the "spit test" , so you can actually kinda FEEL the pipes . Almost . Kinda . Um , pipes SHOULD get pretty hot , so don't grab them while the bike's running . Or something . When you do it right ,. you can feel the spit sizzle instantly under your finger . It's kinda neat .
