How often do you guys change them, are they are to get out (compared to a car or something) how do i get to them? and what brand do you recommend.

 

Replacement whenever they break. Yes they are harder than a car. With small hands. NGK Iridums.

 

I would change em about 20,000 miles or so. Some people change sooner.. If you foul one... I would change em.. they never seem to run right after one has fouled.

Depending on bike, it can range from hard to harder.... Some bikes, a simple gas tank removal and the airbox removal and your there.. others like mine, have to be got at from the front of the frame... major pain in the butt.

+1 on NGK iridiums.. Stay far far away from champion plugs.

 

+2

 

thanks guys. I only have 6,500 miles but its an 03 and i am pretty sure they have never been changed or anything. I am just looking for ways to keep the bike running well and keep gas mileage up.
