    getiing a 2011 !!! what do i need to know ?

    Yep it is that good!! I got my 2010 for 6399 plus 400 for shipping. Great deal!! I took the linkage apart on mine and regreased it. I thought that the grease was kind of on the slim side. Also I would change the oil after the first hour of riding and run non-synthetic oil for at least the first four hours to allow the rings to seat good.

    A hair Rich?

    My bike seems to runs flawless. I run in temperatures from about 60 to 90 degree at elevations from about 2000 to 4500ft. My main is a 168 and pilot 48 fuel screw at 2. My problem is when I pull the plug it appears to be running a hair rich. Not rich enough to be fowling but rich still the same. For fear of messing with jetting because it seems to run so good from the saddle, what is everyones thoughts on running a hotter plug to remedy this? The bike calls for a CR8E/NGK. Do they make a CR7E (slightly hotter)? And what are everyones opinion on doing this, is this this just a bad idea?

    The new 2007 WR...I don't like it!

    What are you talking about?? The X being top of the off road heap?? Everything I've seen puts the WR ahead of the X! Performance, handling and reliability!! http://www.motorcycle-usa.com/Article_Page.aspx?ArticleID=3319 http://www.motorcycle-usa.com/Article_Page.aspx?ArticleID=2102

    I agree with the looks issue. I don't like the looks of it. However, it does look like it will protect the bike well from flying debris. Better then the previous WR protection anyway. As for being plastic, the new plastics today are amazingly strong. But still the same I would be investing in a new steel one as well. Crush one of the aluminum down tubes on a rock and you totally loose the structural strength of the aluminum! Bad deal!!

    Tuff sounding exhaust!?

    I was at the ORV park the other day and I heard a YFZ450 Quad with the coolest sounding exhaust. This Quad sounded incredibly mean. I never got over to where he was to see what exhaust he was running. I know this is kind of a stupid question but I was just wondering if anyone might have an idea as to what it was?? I want that sound for my WR450!!!

    How is low speed perf after uncorking?

    I agree with Matty05, Just try going one smaller on your leak jet it might completely cure your problem. If it gets better then go one more smaller and so on.

    Oil Brand? 10w-40 or 20w-40?

    Hi everyone, I was just curious as to what brand of oil and what weight oil people would recommend for my 2006 WR450F. I typically ride in weather between 60-95 F. My manual says either weight will work, but which would be ideal for a newer engine? As for brand, I am leaning toward switching to a full synthetic like Amsoil (MCF) motorcycle 10-40 or maybe Mobil 1 MX4T motorcycle 10-40. Neither of them come in 20-40. However, You can get both Amsoil and Mobil 1 in 20-50. Currently I am running Yamalube Simi Synthetic 20-40. The thing I'm concerned with is in my owners manual it says not to use oils with a friction grade of CD or higher and I believe both Amsoil and Mobil 1 have a grade of CD. Is this just something Yamaha puts in the manual to keep riders using Yamalube or is this a genuine concern? I was looking on the amsoil website and it says it is fine to run with all Yamaha Motorcycles and will not void the Yamaha warranty, not that my 30 day warranty is still in effect anyway.

    What is the best (for me) exhaust mod

    Thats what I would do. I am extremely happy with the pro moto tip and it really isnt much louder but I didn't remove any baffels. My bike rips with the free mods and the pro moto tip!!
  13. Yes you will loose power past the max horsepower RPM, the further past max horsepower you get the more power you loose. Every engine is different but all generally rev substantially higher then where there max horsepower is generated. This isn't a bad thing because it allows you to get in the meat of your power on your up shifts. I hate to do it, but I'm going to use a two-stoke term "Powerband". All motors have a powerband, your powerband is basically between max torque and max horsepower. It starts right about at max torque (always a lower rpm) and ends right about at max horsepower (always a higher rpm). The difference is in a two stroke the drop-off in power before and after your "powerband" is substantial, therefore the powerband is extremely noticeable. In a four stroke the torque and horsepower loss prior to and after the "powerband" is less. Thus causing you not to notice a distinct difference in power. This is the reason a four stoke will spend less time spinning and more time hooking up. I hope this helps. If anyone thinks I'm incorrect please feel free to debate with me.
