RACETORX HONDA SP1, SP2 FLAPPER VALVE COVERS
Vendor: EDR Performance
Available: In stock
Flapper Block Off Plate.
Dip in power between 5000 & 7000 rpm & an annoying fuelling glitch (hiccup) at 6800 rpms especially with the Moriwaki exhausts and proper fuel mapping
Although all of the bikes are affected by the flapper valve, certain exhaust & map combos enhance this problem.
By removing the flapper valve in the air intake duct you can completely eliminate the hiccup at 6800 rpm & reduce the power dip we have all seen on dyno runs between 5000 & 7000 rpm.
