Whizzing up some spacers for the plate to get it the right distance from the crankcase. Each of the 3 bolts/studs used needs a different length to get it to line up properly. Paring off the 90 mm diameter retainer. Note the 'lip' that will protrude into the case and make contact with the seal, which sits <> 1 mm below/inside the case. The nylon bit now bolted with countersunk 5 mm screws and nylocks to the plate. Nice and snug. Should be enough clearance, <> 1 mm from the pins on the RK EXW which is 1 mm overall wider than the DID VMs used previously. Might not fit with a stock 525 though, I'm using a 520. All back together, started up, and the seal is retained. What's next, 3rd gear?
