OEM plugs need to be pulled/checked/re-gapped every 4,000 miles and replaced every 12,000 miles. I can run iridium plugs easily between valve checks without the need for inspection.FYI, you can get the standard oem plugs at advanced auto for less than $4 with the 20% off coupon on the site. And they have m1 4t on sale for bogo free.
If you pull the plugs every 4k miles, you are wasting a lot of time and effort for nothing.OEM plugs need to be pulled/checked/re-gapped every 4,000 miles and replaced every 12,000 miles. I can run iridium plugs easily between valve checks without the need for inspection.
Standard spark plugs requirements are much more needy than an iridium pug. Thus the service schedule requirement set forth by Yamaha engineers in the owners/service manual. Going past the required spark plug service can lead to other issues such has failed coil sticks. This is a very common failure on any vehicle of neglected spark plug service.If you pull the plugs every 4k miles, you are wasting a lot of time and effort for nothing.
