Suzuki raider 150 racing spark plug?

Answer 1

The best spark plug for racing in a Suzuki Raider 150 (FU-SC or FU-SCD 150) is the BOSCH Iridium spark plug. This plug does not miss a spark at low (3,000 RPM) or high (11,000 to 12,500 RPM) engine revolutions. It is best used at full throttle races.

The BOSCH Iridium is best used in high-intensity drag races (quarter-mile or more), giving a consistent high power fuel-burning capacity that will not scar the Suzuki Raider 150's piston. Extreme modifications to the Raider 150 engine, coupled with high-intensity spark plugs, may scar or even tear holes onto the piston's top end.

For Circuit Racing, where there is the tendency to use low gears on slowing down, as well as rapid up-shifting to gain speed, the best spark plug to use in the Suzuki Raider 150 or R150 is the NGK G-Power plug. It provides consistent fuel-burning spark on rapid slowdowns (using the engine as a brake, or engine-braking).
