Guest aironepony Posted August 25, 2005 Share Posted August 25, 2005 Just had a service done on the Rosso. After 250 miles the Left side plug looks OK (Toast brown insulator) the Right side has a much paler appearance rather chalky white with a very slight tinge of brown insulator. The bike runs fine and the Dealer says "No Problem". I wonder. Any views?.......... Link to comment Share on other sites More sharing options...
Guest ratchethack Posted August 25, 2005 Share Posted August 25, 2005 Here's another "no problem IMHO" to throw on the stack. Link to comment Share on other sites More sharing options...
gallo_se Posted August 25, 2005 Share Posted August 25, 2005 Is there any significant improvement using the iridium spark plugs? I mean, better combustion? engine running better? more "power"? Link to comment Share on other sites More sharing options...
gthyni Posted August 25, 2005 Share Posted August 25, 2005 longer life, and less oxidation = more secure ignition Link to comment Share on other sites More sharing options...
Guest Nogbad Posted August 25, 2005 Share Posted August 25, 2005 Maybe, but I don't think you would notice. Marginal I guess, but if you want to run them why not. Link to comment Share on other sites More sharing options...

I use Iridium on mine. Have not noticed any power increase, or it should be very slightly,Ignition is better and a small economy of 2-5% on fuel that is for sure at least on mine Link to comment Share on other sites More sharing options...

So, if I replace the plugs at 10000 miles for a cost of $25 dollars, my plugs will be free! I have probably spent 15 or 20 dollars on standard plugs in the last 10,000 miles, just because I like the fresh crush washer at every valve adjustment. So, I have to weigh this: fresh crush washer vs. save money...and the environment. Link to comment Share on other sites More sharing options...
gallo_se Posted August 29, 2005 Share Posted August 29, 2005 Is it necessary to change the settings of the ECU when changing to iridium spark plugs? Link to comment Share on other sites More sharing options...
Guest Nogbad Posted August 29, 2005 Share Posted August 29, 2005 Is it necessary to change the settings of the ECU when changing to iridium spark plugs? 58886[/snapback] No. Just check the gap is correct according to the manual. Link to comment Share on other sites More sharing options...
