Hello Im new to this forum and am looking for some help. I have a 2007 Eiger auto that has developed a bad vibration when moving at about 25-30 mph. I have narrowed it down to the primary pulley in the transmission as it shakes terrible when reving the engine. I know there are two bearings on that side one being the one way bearing and the other looks to be just a plain old bearing and am wondering which may be bad. This all started after a epi clutch spring kit install and I did have the one way bearing in backwards for about two mins while the bike was running before i realized what was wrong. Any advice is appreciated.
