I did some new performance mods to my XR650R supermotard: HRC piston,kibblewhite valves (intake 1mm os),Hot Cams stage 2,ported head.
I also bought the HRC raceplug (NGK R7113 -9).Nice ...but it cost a steep 60 euros ( + - $ 72) :banghead:

Is there any other race plug for the XR650R..with a nicer price tag ? :banghead:

Btw: for extended high speed driving (street supermotard riding)and the stage 2 cam (higher revs) ,is it better to run the optional R7113-10 (or equivalent)?
