I have those, for 2 strokes also. Most of the 450's use them. I stopped using them for 2 strokes, too expensive to replace and didn't seam to last much longer than normal plugs, it matters how your jetting is with anything. I've fouled them on 4 strokes, mostly over-oiled air filter

Yes... They are the OEM plug for my rocket... You can special order them through you auto parts store. I got them through O'reily for 8 bucks a piece... Honda didnt reccomend changing them out on my bike till 25k miles....
