Just got back from the dealer where I took the bike for the recall a couple of weeks ago. While it was in I asked them to service it.
Last week I was messing with the bike and found that they had fitted NGK CR8E's instead of CR8EIA-9's! it did say on the invoice but I hadn't checked it properly.
I rang the dealer to arrange for them to be changed, we had a short conversation, him saying that they are correct and me telling him to check, with Suzuki if necessary. It took him a few minutes to come back to the phone, he agreed with me but said they would be fine and under the service schedule will be changed every 7,500 miles anyway. My view was different and an appointment was booked.
It seems some dealers are still not aware of the correct plugs for the 2012 > DL650
If I had not been on this forum I wouldn't have known either!! (Yes, I know it says in the handbook but......)
The bike now has the correct plugs!
