Thats all bogus info. The psi tatings on the forge site are estimates ONLY. If you tesr the spring rates you will find that the yellow is axtually much weaker than our OEM valve. Use that and you just downgraded. Blue comes oit out to be anout he same as stock and shims only make it better. You guys are missing the whole point of upgrading the bpv if you are keeping it set so soft. You gain nothing that way. The ideal BPV settin is a stiff as you can go without surging. You cant base it on just your psi either. It varys on your mods. Mostly stock with 20psi the red spring made me surge a lot. Now well modded i run the red spring AND a shim at 18psi all day long. No surge. My outlook is if you dont run atleast the blue spring you may as well stay stock.
For those who dont know i do all of forge's prototype work for the ms3. I helped develop and test all of the valves for us. I also have other projects going with them right now.
