In dismembering my '96, I noticed the oil jet located between the right engine cover and the crankcase. A bit of head-scratching tells me this is restricting the oil flow to the ass end of the motor.
If memory serves, when I went to Suzuki Service school around 1980, Suzi-Q was doing this sort of thing as a way to restrict the oil flow to parts of their engines. They used a jet, with the logic that if failures in the field pointed to oil starvation in one part of the motor or another, the jet size could easily be changed.
Honda would probably have just done an additional million hours of testing, and decided on the perfect size

So, since the Savages are known to occasionally munch their top ends, I wonder if playing with the jet size is in order?
A smaller oil jet would divert more oil to the top end. Good news.
A smaller oil jet would allow less oil to the trans shafts. Maybe bad news.
Problem here is that shy of a million hours of destructive dyno testing, the only way to know is to try a smaller jet and ride the bike.
If it turns out the ass end of the motor needed all the oil it had been getting, and now isn't getting enough, the rider could be treated to an anchor seize, and a trip over the handlebars. Not good.
Anyone try screwing with the jet size yet?
