I've got a Lectron carb, Scalvini pipe and silencer, Warp9 wheel sets, Warp9 pegs and a "Black Edition" head on the way from HTM Racing in Italy. I'm putting Racetech Gold Valves in tomorrow but it seems you are a step ahead swapping out to the Showas! I only use mine for Motocross.

With regard to forks, I don't think that Gold Valves are a good idea for motocross (in general), and I don't see why you converted to Showas (unless you went to a new twin chamber Showa, but even then...).

The KYB forks on the newer WRs are decent quality units, and there is no reason they won't work with proper springs and a MX-oriented revalve. They ran the same forks on KX250s in the mid-2000s, and those seemed to do just fine...

Why switch to gold valves, instead of just doing a revalve of the stock stuff?

My 08 WR250 .. Stock bike as far as I know except for the pipe ... I believe in the Husqvarna badged bikes ...








Holeshot ...



And I ride this bike everywhere on this island :0) ....
DISCLAIMER: My bike but not me riding .. Ayen, my rider, on board ...

I've had the forks revalved several times, put correct rate springs in, adjusted oil height several times and never found a good setting. (Could be i don't know what the heck I'm looking for too)That being said I figured I would try some tuners theory that gold valves allow for more oil flow (stock valve ports are fairly small) which in turn allows the dampening to be controlled more with the shim stack.

What is your problem with the stock/revalved forks?

I'm doubtful that I will have anything useful to suggest, but I am curious.

There is nothing better for a Wr 300 then a set of Ohlins front and rear $3500 but worth every penny Even if I got a new bike Husaberg/Husky next year I would but Ohlins on it I have already checked with David at Fast Bike Industries and YES he can install the Ohlins on the 2014 husaberg TE 300
You want the best well there it is

Not supple enough in the breaking/acceleration bumps and then it would bottom hard on big G outs. I raised the oil height and that helped the bottoming but still trying to get the breaking/acceleration figured out. I race a lot at Glen Helen(REM) and the only smooth part on the track is the start, it is brutal!

just a few photos at Racetown 395, bad day since their water truck broke!

Start getting use to the dust and come race in the desert No gate feee ride all you want before and after for free 80 to 100 miles cost about 60 bucks no water truck needed

You desert guys are too crazy for me I like to know what's coming all the time.

Really Have you ever done a desert race I hate motorcross yet i still race it from time to time I hate comming off a big jump and not knowing what might be on the down side I have seen many a rider hit from the blind side on the track.But you are correct desert guys are crazy as we will race moto cross,Grand Prix,Enduros, Extream events like Last Man standing and King of the moto We also like to dual sport Yes desert guys are crazy about riding and will ride just about anywhere I guest it take all kinds
but the thought of just going around in circles allway having the pits and my truck in sight is just one form of racing.If you ever want to try a desert race let me know and my club the 100s will help you john

thank you :-) changing pipe and silencer with Scalvini what changes? with the original pipe and silencer, couple on the bike has very low, which I appreciate very much in enduro, but in the field of cross I can not take full advantage of the engine. Changing pipe and silencer what the difference? thanks :-) ale

I find my 300 to be very lazy on an MX track and have tried all sorts of things to correct it, jetting, gearing. I just can't seem to get it to rev fast enough. I'm thinking the CR ignition might be what I'm after with the lighter flywheel and all but have not tried that yet. Don't get me wrong my bike runs good it's not a lack of power thing, it just doesent happen fast enough any input would be great. Not trying to hyjack this tread but thought his question was maybe similar to mine.

^^^ I suppose the 300 is meant to run that way. My 250 is opposite of what you describe. Only mods are higher compression and FMF exhaust.

Thats funny you say that because I was thinking that the 250 might have been the better choice for me. Not because of power just the way it's delivered. Anybody have a 250 cyl,head, and power valves they want to part with. I've been considering trying this.

I have both a Wr 250 and a 300 the 300 has the Cr electronics it is all stock except with a FMF pipe and a stock carb off a 2006 Wr 250

The 250 seems to rew quick but does not get the power to the ground like the 300 The now CR 300 revs fine to me and gets the power to the ground
I see no reason to change anything It will still lug down low and not stall I ride a lot of KOM stuff the tighter the better a long with the Desert racing
I run 13/48 every where I go Even tho both bikes are stock I do run straight race gas 110 octane mixed 40 to one

The Scalvini pipe and silencer feels better on top.
