Glad to see another fellow Alaskan on the site. If you ever make it to the road system on the Kenai penninsula, look me up. I have some fantastic trails locally.
My WR was seriously lean for the weather conditions present when I purchased it in March. I have since backed off quite a bit on the jetting. I have learned alot about getting this beast more in the ballpark with the varying weather. The difference is very subtle but it is there. I would like to compare notes with another rider from this area.

Just because your bike is running, doesn't mean it is running as good as it can. As for tinkering w/ my bike, all I can say is I am more educated about my bike.
The only thing I have left to do is to disassemble/rebuild a shock. The rest of the bike is cake!
I would rather pocket $50.00/hr than to pay some "Official Local Yamaha Mechanic" to do something that I am better at than him.

Can you tell me when the times you change jettings are? By the time I get my jetting perfect, It will be time to change it again. With a 48 pilot installed I need to turn my fuel screw out 3 or more turns. Should I run a 50 pilot with fuel screw out only 1-1 1/2? I almost have it perfect but I don't like having to turn the fuel screw out so far for fear of it falling out while blasting down the trails.

I would not go up to a 50 pilot until winter riding. I am still with the 48 and am switching to a 42 when it gets hot around here. Yamaha four strokes seem to like richer pilot circuits. There is a lot of debate on how to set up your carb's pilot jetting. I adhere to the richer circuit while others like to go down as low as 35. Your off idle response is what you should be looking at to determine which way to go. You do not want a bog or hesitation off idle. Pilot jet is just one aspect to the pilot circuit. Obviously everyone agrees that the zip ty air screw should be between 1 to 3 turns out before a pilot jetting change is needed. If you are at three turns you will need to go smaller when it gets hotter in your region of the country.

Hey Blireef, Most of us members dont have an issue with you not touching your bike. I do have an issue with your thread. We are not attacking you and NHKevin, myself and others here are trying to voice our opinion as asked by you.
Be Happy ride and join in when you can on this awesome forum. I really appreciate the expert input from members like NHKevin and I would hate to see them leave this forum because of threads like this. Now go ride your bike!

I would hate to see them leave this forum...
>> I ain't going nowhere!
Just a bit of FYI history:
James Dean and Clarke Mason were our two original carb guru's. They were both working on carb needles, grinding needle tapers to make OUR bikes work better.
James sent one of his needles to Yamaha. The end result is James needle made it on the 2000WR!!
Both those guys went on to different bikes (KTM and Honda XR650R) but their niche has been carved forever on our WR forum!
That is what trying to improve upon a design is ALL about!!

I felt much like you about my yz400, only a little tinkering with the jetting. Then I got the wr450, I did all of the free mods one at a time to check the change each time. I felt much better with the mods. done, but still felt the bike didn't rev as quickly or pull as hard as it should. I started with the jetting specs. that seemed most common with my location & alt. that I had seen posted on this GREAT forum. WOW! It became a new bike, what a blast to ride! Your bike may be ruuning great, but you will never know if you don't try it.

You should try a leaner pilot jet. If all else is set up right with your carb. The air screw leans out the pilot circuit as it is backed out. At 3 turns you have adjusted it to full open. You need to start with a leaner pilot jet and look at changing your leak jet to a 40 while you are at it. Every bike flows a little different. My 48 pilot is still at 2 turns out on the air screw. I would try moving down to a 45 if you are at 48. Jetting still seems to be a black art to me and there is some conflicting concensus on pilot circuit set up. When you got it right its great and when it is not it can be hell. Dont give up let us know how the rejetting results turn out.

And these aren't XR400s that you can hardly change the oil if you want and ride forever. I'm trying to get the best out of a high performance bike. It has always run but I never have dialed the jetting in. Up here it is quite a bit tougher to figure out. I'm going on four years now and I never have figured it out.
The smart money was to leave it WR timed and jetted the from the shop at pick up. But then I wouldn't have learned anything about how to work on them or how they run. Where's the fun in that? Frustrating at times, more than worth it when I learn something and figure it out.
