84 airheads valve recession
I was happy, if a bit dubious, to read Matt Parkhouse's article in the latest ON, in which he says that the infamous unleaded gas valve seat recession issues are mostly a pre-1984 issue. I thought the 84s were equally affected? As the owner of an 84 (no issues so far, but I keep a watch on it) I'd love to think this is true but it's not what I've always understood. Thanks - B
Valve Seat/Valve Problems '81-'86??
Note...I really meant to say '81-'85 on the post title...
Where is the information that indicates the problems extended all the way through the 1985 models? Everything I've ever seen, by many experienced mechanics/owners/gurus, has indicated that the problem was really through 1984. This whole thread started with a comment on Matt's latest ON article where he states that it was through 1983. How could that have gotten through review if the new "end date" is now 1985? Matt's comments for '83 was the first I'd ever heard that early...now it's 1985? There seems to be too much disagreement in this...over such a wide period... :dunno
