xs650 valves in xs400 engine??

[deadrabbit]

Does anybody know if xs650 valves are compatible with an xs400 engine? What about the using the valve guides to a 650 on 400 valves?

go here

find your year, model, part, click on part and it will list all other models that used the same...
it helps if you mention what year/model you have or put it in your signature

I have a 1977 xs400d

The 650 valves are much larger than the 400's so no they won't work

Yeah, the XS650 is a completely different motor.
