Is it worth getting fully synthetic oil for my cb400sf nc31 1995

on eBay there is alot of combo deals that include oil filters but so I'm thinking that generally semi is used on this bike but I want to know if its worth it or not to go fully

Thanks

I am more than happy with a semi these days.

I've raced for many years and then done track days on my FZR with only semi synthetic oils with no problems.
I think they were designed for semi synthetic oil in the first place. Remember these bikes were designed over 20 years ago in the late 80's when fully synthetic oils weren't around.
