After setting my sag I get a slight kick (right/left) in the rear end over some jumps. What should I look at first, compression, rebound, or something else.

BTW, it's a 2009 YZ 450F.

Thanks,


P

are you letting off the gas right as you go off the jump?

Rebound. Slow it down.
For you to be sure run through the full sag routine if you haven't.
Bike on stand, bike static bike with you on it.

Yamaha has excellent manuals with their bikes - or used to. Consult the manual start fresh.

very doubtful you want to slow rebound down.That is what most riders do and it is the wrong direction.

On most shocks the rebound screw bleeds both ways,compression and rebound.So.as you screw it in you stiffen compression.

What you should do is go in 5 or 6 clicks and ride it,you should notice the change,then go back and then 5 or 6 clicks out and ride it.One way is the right way.

If the track id dry and choppy the more open you run it the better you are.

On sand you want a firmer ride so go in till you like it.

The best thing to do P is get a screwdriver and learn what it does by clickin' and ridin'

Thanks everyone. I'll work on the rebound and see if that takes care of it.

Hey Hillbilly, how have you been?

BDOG - I really like the bike. It seems to be just right for me. I'll be at Birch Creek on Saturday, you should come out.

And while you're doing it, write everything down, including where you started.

If its happening in the air or as you leave the jump, unless its G- out jump faces, has nothing to do with suspension and everything to do with you.

If it happening when you land, its caused by to stiff of compression or to much rebound which holds suspension down into the harsh part of the stroke, kicking it side to side. Try going softer 2 clicks at a time on compression or 1 click softer rebound, speeding it up.

Is this on landing? Sorry P I was wrong. Yes speed up the rebound. TWO clicks at a time. Dont go crazy or you will be on your head. I was thinking of it hitting you in the ass. Try to stay on the throttle and not land dead stick.

Thanks dude!

Tiki, it's happening right after leaving the face on high-speed big jump faces. It's only happened a couple of times and then once entering a corner. I'll see what happens tomorrow and I'll check out MikeyMeanie's info.

Thanks for posting that. I usually do what Hillbilly said, but that chart will be nice to have as all I do now is off road and I have CRF really bad now.
P is that suspension already broke in? Seems like you just got that bike.

When you take back the rebound on the shock go a click or 2 softer on the forks compression. If the shock is rolling through the full stroke, it's possible the front is too stiff and the shock is doing all the work

Cool, thanks.

oldx, yes, it's pretty new. I've only had 4 or 5 ride days on it.

Weird, I just clicked the link and it opened fine... it's a PDF file on a webpage, however that works. Maybe your browser can't read it.

If you want, I can try to save it and email it to you... PM me your email if you want.

There was some kind of issue with my Adobe.
Downloaded the latest, works fine now.

Cool chart, thanks.
