My kicker pedal was quite tight and hard to kick over, so I removed the gear case to have a look. The previous owner had replaced the bushings on the gear case side. The fit was so tight that none of the cams would turn individually by hand. I honed the bushings so each cam can be turned by hand. Two questions:
1. There were four thrust washers, one on the engine side of each cam. Should there also be a washer on the cover side of the two front cams?
2. Can the cam end play be checked with the gear case cover on, and the engine still in the bike?
