Please bear with me here, but wanted to bounce this off the board.
Got a call last night from a young guy who just finished his 1st top-end rebuild. He hasn't done the wiring yet, but said that when he kicks it thru, he's hearing a metallic "chink" near the left-side exhaust. Told him that it sounds like an unseated pushrod & asked him how he had installed 'em.
Here's where it gets interesting: He & his friend (an experienced wrench) were doing the pushrods/rocker boxes together. A dab of grease on the bottom pushrod cups, located onto the tappets. Valve adjusters were backed off, then adjusters held back in the "up" position while installing the rocker boxes. The kid's on the right side of the bike, the friend is on the left side. They carefully lined up the rockers w/tops of pushrods, seated the rocker boxes. While the friend is holding the exhaust rocker box in place, the kid is holding his adjuster "up" while quickly installing the rocker box bolts & nuts. While he's doing this, he notices that his friend quickly flicked the left-side adjuster down & up twice in rapid succession ??????????
After installing the bolts & nuts, the kid turns the adjusters in to put slight pressure on the valve stems. He torqued the bolts & nuts to spec, his friend went home.
Next day, the kid adjusts the valves, buttons it up & has this "chinking" noise on the left side when kicking it thru.
I told him to tear it back down as far as the head, check the left exhaust pushrod for seating & to ask his "friend" (an experienced wrench, remember) where he learned the "adjuster flick method".
Your thoughts please, 'cause this is a new one on me.
