Not another spark plug question...

I will spare us the typical spark plug debate of iridium vs. typical.

But, I was wondering how often everyone pulls or changes their plugs. The plugs I have will last a long time, but I am afraid of seizing the threads if I don't pull them. However, on the other hand, pulling them yearly may crush the spark plug gasket and not let them seal like they should.

What are some experiences here?

I haven't used the Iridium plugs yet, but any time I've removed the plugs, I've changed them.
If I did go with the Iridiums, I might consider using some hi-temp anti sieze.

Definitely use anti-seize and you won't have any problems getting them out.

I've had mine out a few times when messing with the carb screws, always put a dab of anti-sieze on them just to be sure.

Anti sieze is the way to go though I've never had a plug sieze in either the bike or in any car I've ever owned when I haven't used the anti sieze. I use it now because it was recommended and I have a lifetime supply at this point. One bottle of the stuff goes a long long long long long way.

Just be careful not to get Anti Sieze on the electrode, will cause a plug to fail early.

Good point, Chad. Thanks.

I have the iridium plugs I installed last year and was wondering if I needed to take them out yearly to keep the threads clear. I did put anti-seeze on the threads, but did not know if the stuff "disappeared" after some time. As I understand it, the plugs themselves should last a while, I just didn't want them to take out the cylinder threads on the bike when it become time to change them.

OK- I will put a "plug" in for the iridiums.....They are great.

You do not have to take them out, but sure can tell a lot about how the engine is running by having a look. Need to re-apply the anti-seize when you put them back.
