Hello. from the alpha catalogue (http://www.alpha-bearings.com/Big%20end%20Catalogue/Ariel50-350.htm) looks like you need 3 bearings for the engine....I think in reality you need 4 pcs. 3 for the drive side and 1 for the timing (http://redhunter.com/ariel/diagrams.htm)...can someone confirm that? Thanks to all, Devis V
