scorpa4banger Posted May 22, 2008 Report Share Posted May 22, 2008 Hi , Im using BKR6EIX in my 07 sy250 and they are great . same plug for 7 trials so far and it still is in good condition there like 13 dollars AU instead of 3.50 for a cheap one but they are worth it at least they are on my bike Quote Link to comment Share on other sites More sharing options...
andat Posted May 22, 2008 Report Share Posted May 22, 2008 Same theme, but for SY250R (2007). Birkett recommends NGK BKR5EVX, but when I went to my local trials dealer this week for a new plug, he said that the NGK book stated BKR6EVX. Having fitted the new plug there is no discernible difference in performance. Can someone enlighten me as to the difference between 5 and 6 in the plug code?
