The part shows up in catalog and cross-reference listings tied to the A65 across the 1966-1972 production years, so if your bike falls in that range this is the number to be looking at. As with any valve job, check it against your specific head before ordering and plan on doing the intake valves as a set rather than one at a time.
We don't have a lot of extra detail on file beyond the basic listing, so if you're unsure whether this matches your engine, call the shop and we'll help confirm before you order.
