This is an epoch-making device that is activated only when the engine is started, and reduces the load on the cell start of an engine with a high compression ratio by releasing a part of the cylinder pressure to the exhaust port. When the engine is started, the valve of the release kit closes and returns to the original compression ratio, so there is no need to worry about power loss in normal riding. If you are using a heavy tuned engine for racing, and the compression ratio is too high and the starter does not turn, please try this product. The manual type is also available. For installation, recommending the special tool (No. 013151) of related products.
*Compatible with the heads equipped with 14mm Hex release plug bolts at the top of the head.
