Hello All,
Can I ask for some advice?
I am currently rebuilding my 400f engine.
I have just replaced the cylinder block.
The Honda parts list shows two parts (12901-333-000 valve pile control) which I do not seem to have.
Certainly I did not take them out when I stripped the engine.
Can anyone offer me some advice?
These parts are described as obsolete by the usual suppliers.
Are they essential?
Thanks,
John
