what plugs should be used i find that the cylinder on the starter side likes to foul a bit every so often.....someone told me to run a hotter burning plug in that cylinder im new to bombadier products and want to here from you mach guys thanks for your tips ahead of time....Dave

I believe they should be the BR-8ES or the BR-9EVG, at least that's what my shop manual say's.

i run br9es.

i was told to run br9ecs.

but then i found a place that says to run br10es.(denis kirk)

you pick one and see how it runs.

They call for br9es.

All the 700 triples (all triples for that matter) should use NGK BR9ES spark plugs with a .018" gap. Ski-Doo released a service bulletin that covered this for the triples.

You can also use the BR9EYA, BR9EV, BR9EIX plugs as well (those three are anti-fouling designs). I have good luck in my 97 Mach 1 with the BR9EYA's with stock jetting. They don't foul as easily as the BR9ES.

Whatever you do, don't run the BR8ES plugs in your sled.

Quick question. We had a buddy with a 98 Mach Z that was running BR10ES. He ended up burning down.(Lean burn) Could that be a plug Problem??

I don't think so, the br10es is a colder plug, the br8es would be more likely to cause a melt down
