575 suspension help

[evo2]

i've just bought a new 575 which is my first ever full suss so please bear with me because i don't really know much about rear suspension.

i watched the video on mojo for setting sag,so i set it for 25% but after a few pedal strokes it seems to go to 50%,so i've upped the shock pressure today,but exactly the same after a few strokes i end up with 50% sag,if i lunge forward and cause the bike to extend then sit back down it feels right again but then after a few strokes it settles back into 50% sag,so what am i doing wrong?please go easy on me as i say never set suspension before in my life

by the way i'm about 14.5 stone and latest pressure in shock is 200psi

thankyou in advance and hello from a new member ;D

OK, if your in the UK, you could come to th UK Tribemeet and get Mojo to set your bike up for you.

Are you doing the sag with all your riding gear on? and Camelbak full?

I find my 575 is better on RP23 setting No2, and does not bob but works great off road.

My old 05 did you a little of what yours sounds like it does, but I made sure the RP3 was on the full on setting, and put it to the middle position for off road.

Does your shock loose air after you have sat on it? There could be an issue with the shock.

Yeti has a high level of factory tune on the shocks, and if your shock is an aftermarket replacement, then it might not have the right level of tune, on the RP23 there is a little sticker with some lines, and the coloured line is the level of tune, longer line = more propedal settings.

for the record I am about 11.5st, and use around 140psi.

spoke to mojo for some advice,its my understanding of the set up that was at fault,so now armed with a bit of knowledge i'll have another go at it
