pep boys has champion platinum spark plugs for free(mail in rebate)

[Jeffrey]

Actually there is no Champion that I could find that is platinum and fits the KLR650. The Premium Champion I found isn't platinum. But for KLRistas sake I came up with a fairly exhaustive list of usable spark plugs: NGK DPR8EA-9 or ND (NipponDenso) X24EPR-U9. For Iridium, there is the NGK DPR8EIX-9. You can also use a Champion 809(RA6HC), which is available with a 5/8" hex so you can use commonly available spark plug sockets. The Autolite 4163 and MP4163 (premium) are also choices. Gap is 0.032-0.036" (0.8-0.9 mm), torque to 10 ft-lbs (14 N-m). NGK, Stock- DPR8EA-9, Platinum- DPR8EVX-9, NAPA Stock # 2872, recommended gap- .035 inches, Iridium- DPR8EIX-9, NAPA Stock # 2202, or, DPR9EIX-9, prices seem to range from about $6 to $9 dollars each. DENSO, Stock- X24EPR-U9, Iridium- IX24B. AUTOLITE, Stock- 4163, Platinum- MP4163. ACCEL, Stock-0882. CHAMPION, Stock- 809 RA6HC, Alternate Premium- 8809 or 9701 iridium MOTORCRAFT, Stock- HGS22C. AC/DELCO, R121XLS SPLITFIRE, Stock- SF-416C, Platinum- TP-416C. BOSCH XR5DC, This is a resistor plug (as it should be) with a hardened silver electrode. You may have to order this plug through a foreign car parts store Evidently the Kawasaki Voyager and some BMW cars take the same plug as a KLR650.
