Title: Iridium
Post by klx650sm2002 on 10/17/10 at 10:08:45

I've just read on the SR500 forum that a guy fitted a pair of iridium plugs to a XS650 and gained 2 hp on the dyno, this is the first time I've seen anyone put numbers on it.

New std plugs on the dyno then put the guy's old iridiums in and gained 2hp.

It's a known fact that it takes less voltage to fire the iridum's.
could be that his compression was high enough to cause the standard plugs to miss.

I had one in my Savage, and I put 4 in my Miata,I could actualy feel the diference with the bike,not so much with the car,maybe I didn't have the car long enough to notice any difference. I just knew I liked them so I put them in as soon as I got it.

I also think I feel a difference in performance on my savage with a iridium plug. Not much but it feels like it runs a bit stronger.

Mick -

Did you get rid of the Miata? I saw one in a parking lot yesterday, and looked it over very carefully - kinda interesting.

Before you gaze upon it be sure to wear your sunglasses.

Mick -

As I think I've said before, I've always been in love with the Brit sports cars of the 1050s and 60s. I've owned an AH Sprite, Jag 150, TR-3, Sunbeam Alpine, and an MGA.

Recently I was thinking about getting either another TR-3, maybe an MGB, or maybe an Alfa Spider.

Then I came to my senses and realized that I don't have all week to work on a 50 year old car just to drive it on Sat. or Sun.

While I'm basically not a fan of many Japanese cars, since most of them are so commonly boring, the Miata looks interesting because it appears to have a lot of the flair of the old Brit cars, coupled with modern reliability and some creature comforts like a top that doesn't leak in droves, roll up windows that actually do roll up, and air conditioning.

Do they have cruise control?

What do you know about the various years, the differences, any things to avoid - those sorts of questions?

In a way Jerry they are very much like the old brit sports car except much more reliable, mine is a 93 I think in 98 they put a slightly bigger engine mine is 1.6 later ones have 1.8,they do have timing belts that must me taken care of at 50.000 miles, but unlike other cars if the timing belt snaps it's not the end of the world,Every time I go out for a drive I love that car more and more, and how many times do people just go out for a drive ?, I have to invent places I need to go.
And it handles like a dream,like sh1t to a blanket,I can honestly say it's the best car I have ever owned,I would get a new one if I had the money,meanwhile the one I have is perfect.If you can swing a new one that would be great, might be better off getting a late model used
even so if I had the money ,a new one it would be.
BTW there are all kinds of Miata clubs if you are into that kind of thing ,rally's and so forth,not my cup of tea but they are out there.
Hope that helps, Mick

Do Miatas have cruise control as standard? I'm addicted to it - I can't imagine driving any distance nowadays with my foot on the throttle pedal.

A pal of mine replaced the standard plugs in his H.D. Road King with iridium plugs and was favorably impressed with the increase in fuel milage.

Yes, in fact, I won't drive an automatic; I hate them. I prefer to control the engine rpm where I want it to be.

I have iridium plugs in my Suzuki S 50, put them in cause it was a pain to start originally, now I'm no sure it was worth it, I think being hard to start is just a part of this bike, especially when it's cold (below 70 degrees :P )
