Push it to the limit - Spacer Cylinder Head and base for long stroke shaft tuning.
Thicker base and head gaskets/spacers are required for higher-set cylinders and crankshafts with extended stroke.
Available as gasket cylinder head or cylinder base.
Available in thicknesses of 0.5 mm, 0.8 mm, 1.0 mm, and 1.5 mm.
Adapted for various cylinder sizes.
When using a long stroke crankshaft, half the length of the extra stroke must be compensated for by a head and/or base gasket.
Compensating with a base gasket increases outlet and overflow timing significantly.
If the outlet is also raised slightly by milling, the engine is optimized for higher speeds.
Compensation with a head gasket extends exhaust and overflow times only slightly, with a greater change in overflow time than exhaust time (less pre-discharge). This optimizes for more torque at medium engine speeds.
Example: If installing a cylinder with a 46 mm stroke crankshaft instead of the original 43 mm stroke, the 3 mm difference must be leveled by a 1.5 mm gasket.
1.5 mm compensation base: Wide rev range and high horsepower, but low torque and late, sudden power boost.
1.5 mm compensation head: Brute torque and risk of wheelie in lower revs, but lower peak power.
Head gaskets are available in 0.5 mm, 0.8 mm, 1.0 mm, and 1.5 mm thicknesses; base gaskets in 0.5 mm and 0.8 mm.
We offer various cylinder head spacers with 43 mm diameter for racing cylinders around 63 cc and spacers with 47.4 mm diameter for racing cylinders with 73-74.6 cc.
Cylinder base spacers are available with 46.0 mm diameter for 50-63 cc cylinders and 50.0 mm diameter for cylinders up to 73 cc.
Depending on the cylinder, the base gasket should be individually adjusted to prevent it from lying over the overflow channels.
Gaskets for the cylinder head and cylinder base can be combined depending on requirements.
Ensure spacers are lubricated with sealing paste before installation.
