Spindle — throttle arm
Throttle spindle from the manifold and throttle linkage assembly, the shaft the throttle arm pivots on to work the carb slides.
70-9251 is the throttle spindle out of the manifold and throttle linkage assembly on triples-era carb setups. It's the shaft that the throttle arm pivots on, connecting the cable pull to the linkage that opens the carburetor slides in unison. The old book number for this one is E9251, so if you're working from an earlier parts list that's the same physical piece.

This one shows up across catalog entries from 1969 through 1974 in the throttle linkage figures, which tells us it's a mainstay of that linkage assembly rather than a one-year oddball. Wear here usually shows up as sloppy throttle action or the linkage binding at one carb while the others open fine, so if your throttle feels inconsistent across the bank it's worth pulling this and checking it for wear.
We don't have a specific model or engine size tied to this part number in our records, so if you're ordering for a particular bike, give us a call and we'll confirm it's the right spindle for your linkage before you buy.
