Ultimate Tire Pressure

I usually run about 13-14 for offroad and I was running only 10-11 for the MX track until last week. I got a front pinch flat from landing hard when I overjumped a jump last Thursday. I got a new tube (with 13psi)and ran again there on Sunday and the front feels much more precise or secure or something like that on hard cornering. I think with the 400 being heavier than most MX'rs and me being lardy too that 10-11psi wasn't enough and the tire was rolling to the side on the rim a little under hard cornering with good traction.
I run Bridgestone M77 & M78 which are great for both MX and offroad and wear a lot better than the stock 739's too. I think if you're not interested in MX, then there are probably a lot better choices for enduro type riding but I'm not the one to help you out with that as I haven't tried a lot of those.

You have to try it out..
I run 6-10 in my rear, and 8-14 in front (with HD tubes)
Yet to have a flat! (touch wood!)
People look at me like I'm stupid when i tell them what I run.. but it works for me.
You problem could be too much comp damping in the forks also..

Regardless of air pressure. If you want the bike to turn you must have the YZ seat and tank.

Do you have the stock tank and seat? If so, that's the first problem. They prevent you from getting your weight over the front wheel. I suggest going with the IMS tank and YZ seat.
Secondly, the Dunlop 739F tire is miserable. The 739 rear is decent. I suggest going with a Dunlop 756 both front and rear.
Life aboard your WR will be soooo much better then.

I agree w/ the gas tank/seat and the front suspension. I have raised my forks up 1/2" in the triple clamps. I had my forks re-valved and re-sprung by Pro Action. The fork springs seem to have less preload and the action/reaction is much more supple and responsive.
