2011 WR 150 best mods?

[fire1998]

Looking at buying a 2011 WR 150 and replacing my 2009 WR 300. What are some of the best and required modifications to get the bike to perform at its best? I have the 300 dialed in and wonder if its worth the money to switch to the 150.
Thanks

Fire,
Are you going to be anywhere near Montana this summer? Maybe we can meet up and you can ride mine.

RM needle and IMS fuel tank to get you started.

On my 300 I put a PWK carb, JD jetting kit, FMF Gnarly pipe and FMF silencer. This really made a huge difference. How's the carb on the 150.

Don't plan on being in Montana anytime soon but appreciate the offer

We are in adjoining states and only 800 miles apart.

I'm doing ok with the TMX. I had a 36 mm PWK on it and the bottom end was cleaner but I didnt like the way it fit. Others have used the KTM carb which fits better. The FMF pipe also seems to be easier to jet for. I have the 5 slide and RM needle and am happy with the Mikuni. If I was racing I would probably be looking at other mods.

I have a CR125 and a WR300 and I wouldn't sell either one to buy the other. One isn't really better than the other, but they are vastly different.

I rode the CR in some super steep areas last weekend and it was struggling to haul my 220lb ass up some of the hills that the 300 would climb with ease, but the 125 is the best handling bike I've ever ridden. And it flat rips on anything except steep and loose hillclimbs. They compliment each other well and its fun to jump back and forth on the two.

I added an FMF pipe and silencer and run the stock jetting except needle in #4 clip. It rips pretty good. I adjusted the PV adjustment too far and now my top end is lacking, but its easily fixed and I like that I can adjust the PV opening to my liking. I am going to have the stock top end punched, ported and massaged into a 144, but probably not til next year. I will have the suspension setup for me soon and I just scored a 36mm PWK 'shorty' from a 99' kx125, so we'll see how that works. I'm not a big fan of the mikuni and want all my bikes to have PWK's, so I dont have to buy multiple sets of jets and needles.

So.... get the 150, but dont trade the 300 to do so. And no, I dont have any money to give
The government took it all.

Here is what I have done so far to mine.

The motor is perfect now and I do not have any problems climbing that can be blamed on the bike. On my last ride I went up a long and super soft loose hill with not issues. I just kept the bike spinning and stayed right on top of it all. Then I took a loooong rest while waiting for three 450’s to take multiple runs at the hill.

Jetting is always the key on these small bikes. With the WR ignition it is more critical as any soft spots in the power make it unable to pull onto the pipe. I have had good luck with the stock carb with the RM needle. With the RBDesigns mods it is excellent. But if I was running the WR ignition I might consider the 36mm PWK from a KTM just to make sure it pulls hard off the bottom. So either stock carb or PWK but get the jetting clean.

My 09 needed a power valve adjustment but I am not sure the 11 has that issue.

I prefer the CR ignition as do many others but that is personal preference. You will find long threads discussing the merits of each ignition if you do a search.

I have always ran the FMF pipe so I do not know how the stock on compares.

In my case I would say good jetting and the CR ignition were the major mods. Having the head cut, Walts power valves, and the RB carb mods all added some benefit but were more fine tuning.

The IMS tank is the only option if you need more range.

Then of course get the suspension right for you. Depending on your weight you may need springs. I revalved my forks and am happy with the suspension but your 2011 has different forks and I do not know how they work stock.

I have rode 300 Huskys and 150's back to back (I have a wr150) and a (CR150) for me the biggest benifit of the smallbore is the new style frame. For myself the ergonomics seem alot better on the 150's then the old school 300. It is all up to the rider. I am a pretty fast A guy. One thing I also like about the smallbore are the light control efforts. (and 10 year old could kickstart a 150) The clutch pull, throttle control, etc. are all very light effort. (Why Husky puts a 50mm fork on the smallbore bothers me) Gass Gass uses a 45MM and that to me is better in the woods. You will have to ride it HARD to go fast. Oh yea, another advantage is people get out of your way on the 150 because they hear the thing coming. Stock suspension to me on both bikes is NOT good enough if you are a fast rider. Make sure you have the right gearing and I like the FMF pipe. I have always run the stock carb and had great luck. I vary from 165 pounds to 180<to much beer and food. And the 150 pulls me easily. When I swap to my friends 300 Husky it's not long and I want my 150 back. It is a little intense at times and if Husky put a 250 2-stroke engine in the new frame that is what I would ride!!! (I do love passing bigger KTM's though!) If you can find someone near you and ride bikes back to back (take into consideration EVERYONE sets their bike up different, and what works for them may not for you) that would be better before you ditch the 300.
