250-500cc Wr 250 Power valve settings

Has anyone experimented with the power valve settings other than stock?

if so what changes in power delivery vs settings?

Are there different types of Governor springs you can get for the Wr250?

Any help suggested!

Thanx!

I might be wrong!

But dont think you can change this like the ktm's (spit) you have to buy a power valve control unit like iv got

were did you get this from?

I'm pretty sure Wallybean said he's working on a kit right now that will be similar to the one he developed for the 125. Brad.

they are fantastic, depending what you are riding. and they are rebuild-able

So you can have it really smooth power delivery or you can have the full whack, it has 3 settings

Well Wally, get moving on it!

Thanx Typpyt

I want one of those really bad.

ill find out some more info for people tomorrow if i can

I have a spring kit done for the WR 250/300 with two lighter springs and one stiffer spring. Give Hall's a call and request a kit and they can get it to you.

PS, The WR 250 governor is constructed so that you can't add an inner spring. The result is that you will only be able to move the opening point and not adjust the progressiveness. Now lowering the opening point will give you a more mellow hit but it will be abrupt just like it is stock.

i have found a lad that does the units ill get back to you all

Wallybean, have you thought of using progressively wound springs?

Bill,

Yes, I would love to be able to afford the expense of having a progressive spring made to specs. The prices I have been quoted for this type of spring that matches our needs is costly. Not in the price per unit but in the number of units you have to order to get it made. There isn't an off the shelf spring that matches our needs.(not even close) Minimum orders and still get a reasonably priced spring is in the hundreds and I am not willing to put that much money out there on something that won't sell even a hundred.
