    2007 Crf230f

    I have a 2004 150F, and I just put a 120 main in it. I belive you'll need something bigger than that on a 230. I would start w/ the 135 main (p/n 9913-GHB-1350) considering you're basically @ sea level. The part number for the needle is 16012-KPS-921. Start the clip in the middle setting. If it bogs off the bottom, it's rich, so you should move the clip up (needle down). I'm getting this info off the Wrench article from Honda a few years ago. Your dealer should be able to get a copy of it. I also put a CHM exhaust on mine, and it revs very freely w/ the air box lid removed 120 main, and the power-up needle.
  3. Something is probably blocking the float from sealing. You may want to take the bowl off to see if something is not allowing the float to float. I once had a piece of grass on the bowl that made it so fuel continued to flow.
  4. Another thing about getting a title is that they're usually replaceable by the state. If you take your brand new bike from the dealer with just a MSO (certificate of origin), and you lose it, you're SOL. Nobody can get a replacement after 90 days.

    2008-- Honda Crf450r

    Everybody will know exactly what the 2008 CRF450/250R's will be on 9/5/08 - no sooner. As to when they will ship, it's hard to say. Don't expect one on your dealer's showroom floor before 9/5.

    2008 Crf450r Efi

    All this speculation is quite amusing. TWMX has been correct on a few things and wrong on a few things. Their "sources" seem to be correct sometimes and incorrect others. Everybody in the world will know Sept 6, and before that, there are only a handful of people in the USA that know. My money is that EFI will make it onto the 2009 models.

    Best place to live and ride

    Brian, you wanna' be Idahoan. Anybody who guessed Idaho is correct. You can ride off road year round and the snowmobiling is to die for. Ah, the beauty of elevation changes. There are a zillion places to ride all over ID, and you can drive to No. NV or UT very easily (depending on which side of ID you live on). In the winter, you can drive 90 miles north of just about anywhere on I-84 to find great snowmobiling. Highly recommended.
  8. One thing you have to consider is that a high compression piston weighs more, so it's a bit of a trade off. I'm not sure if you can get the head milled like on a two stroke, but if that's possible, it will bump your compression without having a heavier piston in there. Maybe someone can confirm whether this is possible.

    milliams motowerx dimpled vavles?

    I, too, know Jesse Williams personally, and while I haven't tried this product, I will attest that he is an upstanding and honest guy. I've used his two stroke products in the past, and they worked very well. I had some discussion with him while he was developing his four stroke products, and he was very excited as to how they were working. I can't imagine he'd make this stuff up. I would say that trying the product when you need to replace valves would be a great idea. I have an Alan Olson - built motor in my bike, which has been built to very specific specs, so I can't change anything. If I had a stock bike, I promise I'd give these a shot.

    how many #s in your VIN ?

    It starts with a JH2ME. After that it's unique. Hope that helps. If it's a US model, it WILL have 17 digits.

    Duals on 250 but no 450??

    The real reason is that the pipe that goes to the muffler on the left side of the bike would rob too much air box volume on the 450. It needs all the air it can get in the air box, and it wouldn't work to have the shock, wheel, airbox, and cross pipe all in there. Don't let anyone tell you differently.

    06 CRF250 vx 05 YZ250F

    The valves are actually from the exact same vendor, and they use the same material and coating. If the valves are heavier, they would come up to the seats slower, and thus not as hard. The fact that the exhaust valves are stainless is not an issue because they aren't the ones having problems. I'm not going to deny that the Yamaha valvetrain seems to last longer, but it's not for the reasons you stated. Check out the new issue of Dirt Rider, and you'll see that proper maintenence leads to long valve life.
  13. There are very few dealers in the US that have any clue about what the next model year's changes will be, and I assure you, as a former resident of Wisconsin and former employee of Yamaha, none of those dealers are in the state of WI. The only big change you'll see in the 2007 Yamaha lineup is a YZ150F.
