Spark plugs for 1997 XX


Recommended Posts

I just pulled one of the spark plugs to check its condition, there was a lot of carbon on it. The plugs I have in there are NGK CR9EHVX-9, I probably installed them at least 15 years ago.

They have been discontinued and replaced by NGK 6216 CR9EHIX-9 Iridium IX spark plug. 

Is there any major difference? 

I'm guessing it would be a good time to change them seeing as I have access to them.

Don’t waste the planet’s incredibly small supply of this vital metal on a spark plug for a recreational toy. Use platinum if you can. We should hoard it and use it only where it supports our nation’s vital interests.

Presumably, this is the same bike that you are rebuilding the carbs on in a sister thread. This has never happened to me personally, but I understand that if you foul an iridium plug, it is very difficult to bring it back to life. In case your carb rebuild fails, I would get her running properly with the old plugs, then switch to iridium.
