Getting my suspension rebuilt on my 08 YZ 450 and trying to figure out what to expect. I weigh 180lbs. and every time I'm in soft sand or whooped out terrain, I'm constantly fighting my bike to stay on track..... If I land flat on a peaked out table top, my joints hurt for days....

My suspension guy is going to revalve and respring the front and revalve the rear. Investing $350 so wanted to make sure this is a good investment.

thanks for any feedback!

edit, stock springs should be fine for your weight imo.

you might want to post this in the suspension forum first. I bet you can get it ironed out yourself. maybee just with the clickers and oil level..

Not if you want a real improvement over stock.

you fall into the proper weight range of stock springs, I would not respring. I am 190 B MX, I run stock springs and SMART valving and oil. You dont really feel it when you are trying to, but when you go through breaking bumps all day and you buddies are talking about how bad they are and you didnt even notice them ... you suspension is working well. I dont know what valving your guy is going to do for you but I would look into the SMART kit, it is a proven winner for us YZ guys. "do it, do it" smart valving, do it

"If I land flat on a peaked out table top"

Also what did you mean by this ? Most all suspension is going to bottom of large flat landings. From the sound of it you may be a little low on fork oil, that is really the only thing I could think that would allow you to be blowing through the stroke at your weight.

350 for springs and a re-valve on the front and rear? Holy crap, does he do alot of work around that area? How does the smart kit compare in price?

The are working on the Site at SMART right now but I believe the kit is $180 ball park. It is a DIY kit, you can search in on the forum, there is a lot of info. Also there are quite a few SMART installers around, you can email them and they can direct you to one. I am about 3 hrs from Delaware and I have a SMART guy 10mins from me. Heres the site

My SPI kit included all the oil and parts for $240 plus shipping. This did not include fork or shock springs.

If you use the "Dell Taco" kit from SMART, be sure to get the kit for the rear shock as well. The fork will come out really well by itself, but can't live up to its full potential with the stock shock the way it is. The difference in stability in the whoops at speed is incredible.
