I have a '76 90/6 here I'm helping someone out with with 18K on the odometer that was last serviced at the same dealer a couple thousand miles ago...
valve specs according to the book are .006" &.008"
right side was .004" & .005"
left side was .008" & .0085"
heads are tight...so it's not my imagination.
this dealer guy inherited the business from his father and they've had the franchise for decades in the Pgh area...that pretty much narrows it down for ya.
and the owner of this 900 bike should be walking into Bob's in Jessup sometime this week (or last) looking for carb kits and a couple other parts...he looks like Santa Claus and talks alot...if that's where you're at Paul...the parts are aimed at me.
