154” of 93 octane killer! SP’s newest member of the family of build packages.

This one features JWR-610 Drag Cam and JWR heads.

Nearly cracked that 190 horsepower number, and ride it anywhere. 💪

PSA: If you’re bringing a bike in for a build or just for tuning, DO NOT have any kind of fuel treatment or octane booster in your fuel tank!

This can ruin our O2 sensors and cause tuning issues.

TIA.
