Absolute ditto!
Those particular 70-71 throttle parts are difficult to find.
In fact, just about everything on your bike is difficult to find.
Except for the sparkplugs and the air in the tires....
Hi 2Many,
I'd suppose that authentic Japanese sparkplugs are still available at a premium, but the air?
I see a niche market for the purists amongst us:-
Genuine Japanese air! Pressurized and tanked on the downwind side of Mount Fuji!
