Title: 1977 RD400 Fuel cap seal replacement
Post by: X-Man on April 03, 2026, 10:41:32 AM
So I got a new tank cap seal and I dont see how to get the new one on? My cap does not have the screws on it to disassemble. Do I just heat it up and stretch it over? Can anyone advise me?

As I recall from one I did years ago, just stretch it on there and then seat it in place.

Yeah I tried that after getting it hot in water but felt it was gonna rip. I guess I could always just get another seal if so?
