Found the plug for the 900------nothing cross references

Yeah, if the change is overdue, big BIG difference. Matter of fact, I just did mine this morning on my 800B.

I tend not to change them until the engine starts giving signs that it's past time to do it. I never wrote down the mileage, but if memory serves, I never got more than 20,000 miles from a set of plugs in any of my motorcycles.

I wonder what your experience is on this?

My experience with what? My engine had a fairy serious hesitation when cold, and it wasnt accelerating like it used to. I tried fuel injection cleaner, tried high test fuel, nothing did any good. Spark plugs fixed it...
