Topic: CB400 rings: differetn for each year?

[magconpres]

I have 4 sets of rings for a CB400F, P/N 13011-377-003 (Nippon).

I want to use them in my CB400F1 engine (serial 2001292).

According to my Honda Parts manual, I should be using 13011-377-004 (Riken).

Does anyone know if there are any real differences in the rings other than the manufacturer?  Can I use the rings I have? 

Thanks,

MCP

No difference---use em

Thanks.
I sort of figured it out after posting.  The cylinders and pistons are the same for all the years, so the rings must be interchangeable.
