This is probably a stupid question but I am a newbie, so here goes. I bought new plugs the other day for my 97 670 and I was figuring that they didn't come pre-gapped. So I was wondering what the Gap should be for a set of Br9es? Thanks for your help
It took me a while to remember where I saw that statement myself and with a little digging I found it. If you have a copy of the December 2001 issue of SnowTech it's on page 12 under Ski-Doo Spark Plug Substitutions (2nd paragraph). I checked them as well to be sure, all 4 I bought were set at.018"
Since this post is regarding a 97 670, here`s my opinion...run the largest gap it`ll take without mis-firing or fouling. I run my 583 and 800 3x3 at about .025. The dfference? Drivability for lack of a better description. Motor seems to pull better in the mid range. The reason? If you think about it the bigger the spark, the easier it is to ignite the fuel/air mixture. I`m pretty hard on my motors and have had no adverse effects from doing this. Just my .02
