Spark Plugs

[BobQ]

So tell me, do you really have to change them at 8000? I have 13,000 miles and have not done them yet, and would rather ride than wrench!

Thanks Bob

I've got 39,000km (about 25,000 miles) on mine. Still runs great.

That being said, its getting new plugs (and air filter) this weekend.

Holly crap! I have 27k. I think it is time to change the plugs.

Next thing you guys are gonna tell me is I gotta change the air filter too!

And flush the coolant, and bleed the clutch, and do the fork oil, and the driveshaft oil, and a throttle sync, and check the valves, and the steering bearings, etc.

That's a hell of a lot of work.

recall changing mine for the first time @ ~12,000. They looked good; with new plugs installed I couldn't tell the difference.

It depends on how important it is to you to keep the performance at the maximum. I change my plugs once a year. That is typically between 15 and 20 k miles.

Changed my plugs yesterday (first time I've been under the tank).

Understand, I'm a pretty fair mechanic, but sweet jeebuz is that a load of crap under the tank! Took about an hour start to finish. Thank god for the plug wrench in the toolkit. Even with that, my hands look like I went 5 rounds against a garden weasel.

Old plugs looked perfect, slight gray, no spec's no burning, no sooting.

Today, if the weather warms up quicker, I go for a scoot!
