    Yes, that's the one I used. Significantly stronger than the one that was in there.

    Update: The reseated ball and new spring did nothing to help the wet sumping. I still got half a quart in the bottom of the sump in less than two days. I thought I might be able to get away with just the gearbox but it looks like I need the whole pump. I ordered a new, tested one from Kiwi yesterday and that should solve the problem.

    New pump installed 4 days ago, and this is the amount of oil in the sump. The bike hasn't been run yet (waiting on a new rotor). The wet sumping obviously is far less than it was, but is this a reasonable amount? I don't know where else it could be coming from if not through the pump.

    Never checked mine but certainly that could be mostly residual oil draining into the sump and that small amount is not an issue. You could check after 2 weeks to see if rate of accumulation is same or it slows way down. After you shut engine off just measure down from the oil tank opening to oil level then re-measure every few days to see if level is dropping.
