I have a 2000 f4 with 13,000 miles and I am looking to change the plugs. Has anyone used or heard anything about denso or ngk iridium plugs in a bike. I know they are great in cars but never heard anything about motrcycles. thanks

 

yes as as matter of fact, I use them in my xr285r, and thier awesome. Now on my CBR thats a different story, Iv found tht the iridium actually was a hottish type plug and would use the NGK equivelent on 4 cylinder bikes.
