tyre pressures is one way, try going down to about 12psi from 15.
I bet your rear end has too much compression set on the shock, this transfers
all the weight forward. Set your sag too, it does make a difference.

The standard tyres that come on the wr are not agressive enough. Get a good set
of tyres to match where you ride. I personally like the Dunlop 952's. Great all round tyre.

It is to do with the rear shock, and how to set the stroke position of the shaft.

There is heaps of info on how to do this, but basically you first take all the weight off the rear wheel (put it on a stand so the wheel hangs freely) then take a measurement of the distance between the rear axle center and the rear fender holding bolt. (measurement A)

remove the stand and sit on the bike in attack position or normal riding position. get someone to take the same measurement. (measurement :D

subtract measurement B from measurement A and ideally you would end up with 90 - 100mm (3.5 - 3.9in)

Make changes to your spring preload to get the ideal measurement.

Has your suspension bedded in yet? It takes a while, get a really fat and heavy mate to ride it around for a while. The next time you ride it, the suspension will feel different or softer. if it doesn't, it has bedded in.

I would only set the sag if your suspension has bedded in or you will have to do it again!

Did a quick search and found this. http://www.thumperta...5&highlight=sag

(when you do a search on something you can scroll down and hit the WR section to narrow down the reading) :D

Sag is how much the bike sinks or lowers when you sit on it.

Its adjusted by using the collars at the top of the spring on your rear shock and basically adjusts the spring for your weight.

I set the sag and fooled with the settings and ended up sending it to the suspension shop and had them set it up like the yz. No more front end wash. :D

FWIW, my suspension guru insists that one must stand, not sit, to get true sag.

Once you set sag, and raise up forks 5-9mm so front end sits lower, and back off the compression adjusters under the rubber caps at the bottom of the fork, it should not push/wash in turns.

If it still does, then you may not be sitting far enough forward in turns. Sitting back on the seat tells the bike to go straight per Semics :D )

How much do you weigh?

Very good advice, assuming he rides in soft/wet conditions. I used to use an M12 in those conditions. Now I run Pirelli MT44 with even better results. :D


ps- on compression damping I backed off about 3 cLicks. It helps.

1) the right tires for the right terrain. (stock tires are intermediate/hard terrain)
2) the correct amount of air pressure
3) Proper suspension set up. Start with the sag, then make small adjustments to the adjusters. Take notes when you do, or you go around in circles.

All prior info is good, but of no use if your corning techinque sucks.......

Are you weighting your front in corners, not dipping your shoulder, looking ahead of your turn with your chin out over the bars??? Proper technique will turn a bike, even with the horrid D739 that comes on the bike......BTW, get rid of that tire :D
