With just 3 thousand capital, a damaged starter pinion can be reused 

So for those who experience the same case, you should try this method. ‼️ because it would be a shame if the starter pinion was just thrown away. Pinion starter or what you could call a starter grenade, if you buy the original one, the price is quite expensive. As long as the front and rear gears are still good, we can just use them again by tricking them like the tutorial I made. and as a result the motorbike starter returned to normal, only the front crankshaft seal was double pear.
