spark plugs
 

I am wanting to try iridium in my bike but was concerned if it would be to hot and scorch my piston top , is that a valid concern or am i just over thinking this thing

Don't know the pros & cons of iridium, But I bet they cost more. Just my opinion, but it's a gz you're riding not a top of the range, high compression crotch rocket. Why pay extra for something that's going to be of no benefit whatsoever, when the standard spark plug does its job efficiently, lasts forever, & is what was designed for this cheapo bike. :)

i installed iridium plugs on my car and it increased acceleration and the idle was nicer. I was just gonna try it on the bike and if it was better keep it if not im out 9 bux

You figure at worst it is going to perform exactly the same as a standard plug, and you figure one of them will cost you at least three bucks if memory serves me correctly. so you are only out an extra six bucks and that iridium plug will probably outlast the GZ.

The Vstrom has Iridium plugs in it now. They don't make that big a difference in the way it runs(this bike anyway) but the advantage is the fact that they last so long. Probably never need plugs again for the bike. That is why modern cages have Iridium plugs, no tune ups for years and they just run great. The Iridium tips of the electrodes do not burn off or get munged up like a standard plug.
Had a 96 Ranger with a four banger and 8 plug head. Over 100,000 miles and never missed a beat.

You must check not only the length but the heat range of the plugs. You just don't buy one and pop it in, it has to match what's required for the bike.
