98 zr600 EFI fouling plugs and seems to be getting worse. Last season rode 2K miles with same plugs. now its fouling a plug every 100 miles. Is the oil injection cable out of adjustment or gradually getting more and more out? If so what ius the adjudtment for it? Does it need to move precisely with the throttle injection. Because right now the oil injection is moving before the fuel injection by a little.
It seems like it has always ran pretty rich, even last year.
