2 strokes are very finely tuned and any small change even as insignificant
as changing to a differnt plug can have catastrophic results. I have seen melted pistons, detonation damage, Ring landings broken off the piston.
Do what you want with the plugs but keep in mind Suzuki built the motor and tested it on a Dyno and settled on the R4118S-9. The Dyno runs are not only for horsepower they are for enduance runs also. So if Suzuki put that plug in then you should use that plug. That in itself is reason enough.to spend the 8 dollars on the right plug.
