Spark plug change to Iridiums

Post by EZdriver »

I installed new NGK standard plugs last April when I was reviving it from the 20 year sleep the bike had endured. I've put almost 8000 miles on her since. I decided to put in new NGK DPR7EIX-9 Iridiums last week. What a difference. Starts even easier, runs smoother with little or no low speed stutter, and the throttle response was improved.
I highly recommend these plugs to anyone....

I could not agree more, I put the same plugs in, as well as the NGK caps with new boots. Starts easier than ever, and throttle response did have a noticeable difference!
