If it's only a spacer/protection for the aluminium against the frame then I can use it as is, the groove won't affect it. I'll happily buy a new washer but I doubt it'll be in stock anywhere?
There is no seal in there either top or bottom, yet I got 2 seals with the bearings. I don't suppose much water gets in past the top washer anyway plus I try not to ride in the rain and I'll pack it all with plenty of grease, so Just wondering whether to fit the seals or not?
Whatever I do I need to decide before I fit the bearings.
Otherwise next job is the engine, since I've overbored, gasflowed, high-comp'd and FCR'd I reckon it might be wise to refresh the bearings etc on a 17 yr old engine! (although I can't 'feel' any wear in the crank).
Also looking to get the crank balanced as my understanding is that the factory balancing is not great in the first place so with new (lighter) pistons it's unlikely to be right.
Here's how the engine looks at the moment;
