1999 YZ400 shock vs 2000 426 shock

I just bought a 2000 426, unfortunately i went to adjust the high speed compression and it seems i have a 1999 shock. I guess since the YZ250 and the 1999 400 shock look the same i can't even be sure what shock it is, the spring has 1 yellow mark on it so i guess it's a stock spring. Is the 2000 shock with high speed comp that much better than the 1999 shock? Should i get the 1999 one revalved and just go with it? Is there a MX-Tech around Montgomery Al i can take it to? Thanks Bird

Please help, i rode the bike saturday and it handled like a pig, I really need to know if the shocks are the same as far as size, length etc., I also think the bike may have 1999 model forks, my main question is can i get the suspension working properly with these parts or should i just give up? I want to get them revalved and setup for me; but, i don't want to waste my money if it's not going to work. Please help because this is what i'm stuck with, what really hurts is i was told by people that i thought were my friends that this thing had procircuit susp and it doesnt even have 2000 suspension, i guess i get the 2002 dumb idiot award for this one, hehe

thanks Bird

Oh well I decided not to say anything else, I pretty much know what happened, I can't see how posting anything here would help. Oh well, thanks for the info and the help, Bird
