Anyone try Gnarly or Platinum II on RM250?

I know my 03 has a lot of compression stock, and these RMs were thirsty for race gas. I refuse for race gas to be an option for me. I HAVE a Gnarly that I removed because it ups the compression even more (MUST have race gas). The stock pipe is good, I used fine tuning, flywheel weight and Yamaha's reed spacer to make power delivery more predictable. 1 or 2 less teeth out back helps too.

i have a gnarly pipe for my bike and it works great, it smooths out the hit but it seems like it just has all around more power, i have the grnaly desert pipe, not the gnarly woods pipe.
