Thicker base and / or head gaskets are required when using longer stroked crankshafts, but getting the port timings and squish correct even with a standard crank is very important if you want your scooter to perform to it's optimum.
Thicker base and head gaskets / spacers are required to raised cylinders and crankshafts that have a longer stroke. With compensation by a base gasket, the outlet times are lengthened and the transfer times are also obviously longer, this effects where the power comes in.
If you install a 60mm instead of a 57mm crankshaft on a MALOSSI kit, the 3mm further stroke have to be compensated for a 1.5mm gasket. If you play around with the gaskets on the head and base you can alter where the power comes in, for a higher top speed or a more torquey scooter.
Available in 0.25mm, 0.5mm, 0.75mm and 1.0mm - 0.5mm is standard, please click on the drop-down menu for options.
The top quality gasket material is made from aramid and man-made mineral fibres bonded with nitrile rubber, we use this for all our gaskets. Suitable for sealing out oils and fuels, also water, steam, gases and many chemicals!
