That sucks it was leaking from the clutch cover gasket. I've changed my clutch cover off I'd say at least 10 times for clutch changes/inspections (I'm a drag racer) and I've never replaced the gasket yet with no leaks.
At least you got your bike back and it sounds like it's running good!
Check this out. I bought the g4 2011, with no extended warranty, as never needed one for several past superbikes; just ride until about 100,000 miles on the loop, sell-give away and buy another.
Never had a serious problem with r1's, cbr's and one dorky FZ1; until the '11 10 which blew up at 50k miles. The clutch area was red hot and that foam pad was on fire, low flames, so I just pulled the burning foam off and bike cooled.
ok; I really don't care what the tech does as I don't do any serious stuff, but I suspect tech was asked by kawa to tool the clutch; kawa tooled other areas of the bike but I'm no expert so best not to publicly report as I don't tech don't want to go on record as not sure about Kawa policy and don't want to upset Corp admin.
Kawa corp knows that the g4's are 600's on steroids; I so want the 2019's to come out at the same weight as the g4's; I simply can't handle anymore weight as tire prices keep increasing.
anyway, I like Kawa corp. I didn't like the '11 failure as that surprised me but took a chance on the 13 but the extended and Kawa came through.
