I'm in the process of rebuilding by clutches on a 89 Exciter I just picked up. The weights in the primary say "82m" and the service manual also lists 87m as a weight. What the difference? Also the previous owner said one of the clutches was replaced but didn't say which one. I'm assuming its the secondary because its too big of a diameter (foot rest to clutch clearance) to remove the belt without removing the secondary from the shaft. I don’t know the part number of the secondary but it’s a Yamaha because it has the little symbol on the helix. Is it normal to have a very tight clearance between the secondary and back side of the foot rest? Nothing looks bent to me.
