Yep,the faulty ones were made by KTM,summat to do with the oil pipe unions being pressed in and not welded. KTM later rectified the fault. Other oil coolers were made by Toyo.
Dunno,...dont think so. I'm guessing that some dealers/owners never bothered to fill out the form the first time.I remember taking my bike up to Italia for the check.Took about 30secs as you could clearly read "TOYO" through the vent in the fairing vee peice."Anything to sign?" "Nope." That was that.
