While changing the spark plugs on my 2008 Speedster 150 (155HP), with each step, new, unexpected questions arise. Thanks to forum, I got my answers. The last one (I am hoping) is whether to gap the original/sea-doo recommended NKG DCPR8E Spark Plugs. Some sources state that they come pre-gapped, while several of you on the forum mentioned gapping them to .07-.08mm. Which is the correct/better?
Thanks in advance!
