little leaks can be annoying! Well, upon closer examination, my tw200 the shift shaft seal was leaking. that's just the lowest point of the case when the bike is on the side stand, so virtually any leak will drip off right there.To remove the worn out shift shaft oil seal I had to remove the gear shift lever & left side cover first .This can be done without draining the oil by laying the bike over on its right side. Be careful about leaking gas and/or battery acid if you do it this way..At that moment I didn't have any seal remover tool or seal pick, old oil seal isn't come easily SO I threaded two wood screw into the old shift shaft seal until seal was loose from the engine.I wrapped in elecrical tape on shift shaft ,prevent damaging the new seal when installed it.I always choose OEM oil seal bacause of the longevity .QUALITY IS WAY WAY HIGH NO NEED TO WORRY ABOUT IT. VERY WELL PACKED AND RECEIVED PACKAGE VERY QUICKLY.THANKS WEBIKE ! Webike Always give customers more than what they expect to get, shipping chargers and the products prices are very low. GREAT SHOP !
