Premium v.s. Regular
I am sure this has been debated to death but I could not find it. Just did a top end re-build on my 2003 xlt1200 since middle cylinder was toast and figured hey I am in here do it all and of course fix the issue as to why.
So my good buddy who rebuilds them and did mine says put premium in it. What is everyone thoughts does it need it? Do you get longer life, performance?

You don't need premium on a stock 1200PV motor. Only reason to use it would be piece of mind, with the little bit of detonation resistance it offers, over regular. You won't gain ANY performance.

...only other possible 'argument' would be as summer heats up, going midgrade might give you that extra assurance/performance, and/or run a cooler plug, like a BR9es. And remember NGK is one of the few, if not the only, plug manuf. that when you go up in number's, it's actually a cooler plug. I run 9's in my gp and xlt cause I've got so many air holes drilled everywhere and I want to keep the gas mix as lean as possible for best high humidity/summer weather performance.

i run premium in ALL our stuff now, only because, here, at alot of stations, it is non-ethanol.
that would be my only reason on a stock ski, it to stay away from ethanol.

How does it help resist detonation?
