Not to sound too lazy but, how far into the PV assembly do I have to dig? I will definitely try it, and the NEJ needle! Just wondering if I need to buy a sixer or a 24 rack.

Haha a sixer, and maybe you'll drink 2 or 3. Took me about 30 mins.

Remove pipe, drain coolant, lay bike on left side, remove side cover, remove PV assembly, remove the washer pointed out above. reassemble with PV assembly placed in the side cover.

Only hang up you MIGHT have is having to move the wheel a tiny bit (while in gear) to get the PV assembly gearing to align and it'll drop back in. The side cover gasket can be re-used several times before you need to replace it.

Great info, thanks!

I like the power delivery of the X a lot, but I could see it being improved ever so slightly. Kinda cool that you can experiment with different PV settings. Just the shorty alone opened it up quite a bit.

There's been a lot of experimentation with different washers (different thicknesses and all that) and the general consensus (from what I've gathered over the past couple years) is that simply removing the 1 washer just before the spring has yielded the best results.

However, of course your mileage may vary and there are some guys who enjoy the stock setup more, typically woods only riders. Definitely give it a shot and see what you think!

I'm absolutely not woods only so I will try it

I just had 2 weekends in a Row of Epic riding!

No. I am not a 25 year pulling off big jumps, but riding Honda Elsinore's in 1974 and riding an After Market Product that everyone can buy just goes to show Entraprenures can beat Yamaha at their own game!

Eddie Sanders Racing (ESR) (Pismo Beach, Ca.) makes a $900 YZ 325 with a Cylinder, Power Valve, Weisco Piston, Machined Head & Gaskets to fit.

Rejetting your Keihin Carb (170 to162 Main & 48 to 42 Pilot makes your YZ 250 (now YZ 325) the Best Value Bike on the Market!! Torque down low and a nice after burner hit in the last 2K RPM!

You are so right. technology changes...thats why I'll never buy another 2 stroke without a counter-balancer.

...that big bore will rattle your teeth out, and literally suck every bit of top end power and over-rev out of the powerband.

...a ported, properly chambered, and properly jetted YZ250 (with a cast piston) may not make as much midrange power, but I'd take one over a 325 every single day of the week. The vibration, harshness, and lack of over-rev just aren't worth it.

The Big Bore YZ ESR 325 DOES NOT VIBRATE ANYMORE THAN WHEN IT WAS A YZ 250. If anything, it gives you speed down low with more torque, so you do not rev it as much as a 250. I have had both a 250 & 325, so take it from experience what I said is true.

But the most awesome part of the YZ ESR 325 Engine, is a nice hit forward in the last 2K RPM! Staying with a 450, is now about equal!

I will grant you that your TX300 is a better, less vibration type of engine, the magazine articles loved it, so GOOD for Husky & KTM.

But the YZ ESR 325 Kit (Cylinder, Weisco Piston, Machined Head & Gaskets) at $900, is the best value upgrade for a YZ/YZX 250 for the money. A new Husky TX 300 might be nice, but to get one at list price is $9,199, maybe a used one can be found in the future.

Which ever OEM, KTM, Husky, Yamaha, Beta, Gas Gas, Sherco or TM, decides to introduce a 2-Stroke Injected 350, 400 or 450, you can expect the 4 Stroke 250 & 450 sales to drop big time!

Nice ! How long have you had the ESR 325 & can you speak on the longevity / durability ? I'm assuming your using the oem CDI & 250 expansion chamber ? I've been waiting a couple of yrs. for an 02-07 CR325 kit to be developed from them. I talked to Eddie last Nov. & he let me know that it was close to being done possibly Feb. of this year. I'm seriously considering a kit to try out. Thnxz..

I have had it for 1.5 yrs., but with a daughter going off to college, some major work activity and developing a girlfriend I only have about 30 hours on the engine. Not quite ready to change piston yet, but maybe at 45 hours.

I can tell you that once you ride it on the MX Track & some Off-Road areas, you really appreciate the Linear (almost Electric like Powerband) power of a 325.

It's the best value (least expensive) MX/Off-Road Motorcycle you could have. With a 2-Stroke 325, its Less hassle and more FUN!! .

Just wanted to post an update after some more seat time. I've ridden my 250x at a few tracks, technical PNW woods and the dunes. This is the best motorcycle I've ever ridden and if recommend it to anyone!! My roommate actually just bought one yesterday.

Aside from little setting changes, all I've done so far is add a r304 shorty. I am going to do a few more goodies in the near future, but it's amazing in stock trim. I love this bike and it sounds like a rice crispy.

How is the upper mid and top end compared to a ported 250? I ran the Eric Gorr 295, was a excellent swiss army knife set up but felt like the top end wasnt that great compared to my buddies Derrick Harris ported motor. The low to mid and linear feeling was real good on the Gorr setup though.

I am currently running a Derrick Harris ported cylinder and head. Thing rips hangs with 450's for sure. But I was interested in the 325 kit for a woods bike/ dunes fun bike. Sounds like you like it alot.
