The stock plugs on the GTS are DPR8-EA9, but can be replaced with NGK platinum plugs DPR8-EVX9. The bad news is that your dealer will want $10-$11 EACH! Good news is that you can order them from Advanced Auto for $5.99 each. I ordered on Sat. and they were there the next day. So was the Purolater F44661 fuel filter at $14.99. Just getting the bike ready for riding season. Kevin Hawkins // Greensboro, NC [EMAIL PROTECTED] http://cfm-resources.com/r/raddboy Y2K Kawasaki ZRX1100 //'93 Yamaha GTS1000 //'85 FZ750
