What octane are you running in your 450?
I run 110 usually mixed with 92 in my Honda CRF250R and it loves the high octane. I have run that mix in my Honda 400ex as well and it seems to run better. The 450X shows minimum of 91. Is the general concensus to just run premium; 92 or better?

I have just run 91 or 93 pump gas in mine so far with no ethanol. That was all I ever did with my canondale and it ran like a top all the time I had it.
So did you get the DS yet?

I run 91 pump gas with no ethanol also. Really isn't a need to go any higher on a stock engine.

I run aviation fuel, its leaded 100 octane, but that's is because compression. I ran premium pump gas when my motor was stock.
