●Equipped with bearings●Cannot be installed on engines with cells. ●There is something that slightly interferes with the rib part of the crankcase, so it is necessary to reduce it to a minimum. ●Please use with a centered crankshaft. If used on a crankshaft with large vibration, it may fall off or be damaged. ●By strengthening the support of the 12V MONKEY's longer crankshaft, it suppresses the shaking and vibration of the crankshaft that is characteristic of single-cylinder, 4-stroke engines, and efficiently brings out the performance of the engine. It is especially effective for tuned engines with increased bores or high rotation speeds.
