Jetting proceedures

Anyone have any detailed proceedures for removing the carb and installing a jet kit, e.g. JD Kit? I was looking at the bike and man o man is it shoehorned up in there.

You got that right, I installed the J.D. kit without pulling th carb, rotated it enough to get the main jet changed and a new air screw installed. But then I got the Boyesen pump cover and had to remove the carb, what a bitch :thumbsup: .

The best way I found to get the carb off, or at least up to where you can work on it, is to unbolt the botom of the subframe and tilt it up, then unbolt the top shock bolt and you should be able to wiggle the carb off. After I did it I found a warning to be careful how you pull the air boot off the carb inlet so you don't damage the seal between the airbox and the boot.

Did you have to take out the airbox? Not the gas tank right, what does the Boyesen pump cover do?

Jetting is extremely simple to do. Should take you 15-30 min if you are decent with your hands. The JD kits come with simple easy to follow instructions. You will have to pull your tank. Also there are two vent hoses above the carb that go through a flange on the frame( the only reason I mention them is at first glance the look like they came undone from something but they didn't). Loosen all three clamp bolts on the boots so you can twist the carb. If you have T-handle allen wrenches use them you need a 3mm for the top two bolts on the carb and a 4mm for the nut that holds the needle. A 17mm socket opens the plug on the float bowl. A 6mm socket will fit the main jet which is in the middle of the float bowl plug opening.

As for the Boyesen Accelerator pump it changes the spray pattern inside the carb increasing performance. It is three screws that hold the cover in place. A diaphragm and a spring will come off with the cover. I was able to switch mine without removing the carb. :thumbsup:

:thumbsup: Removing the carb is no joke and takes a long time. I have done it once and it was a pain. :bonk:

      Anyone having or had problems with the starter not turning over easily on the 450X???
      I have read about this problem on CRF's ONLY and not seen anyone come up with a fix.
      Problem being is that you think there is a problem with the battery, when infact the battery is OK. When you have a good fully charged battery in the bike and press the e-start, it turns over very slowly.
      I have checked the electrical circuit and it seems OK. I am wondering if it might be the starter itself - any suggestions?????

      I've studied the Jetting sticky's but still have a number of questions:
      I bought my '06 a couple of years ago and had a smog block-off kit installed and the pilot jet was upsized to a 48 and the air box opened up top only. The bike has appeared to run a little lean at times and got hot on a couple of occasions in elevation and on one other occasion. I'm looking at upping the main jet to either a 165 or 170 to help with the possible lean condition. The bike currently has a 142 main jet in it which I believe is the stock size. It looks like the most widely used Needle Jets are the JD Red, but it doesn't look like they are sold separately, is this correct?
      I was going to also get a 45 pilot to have options for further tuning. My assumption is that every bike is a little different and that where you ride is going to have a lot to do with jetting. We ride mostly, mojave desert, baja, and southern Utah with elevations from sea level to 9,000 feet but the higher elevations are generally for a short period as we generally continue through the peaks and head back down.
      I'm looking to convert from a stock exhaust to possibly an FMF Q4. I want something a little throatier but not overly loud and will provide a balanced flow of intake/exhaust.
      So can I get the JD Red Needle Jet by itself or can I get by using the stock and move the clip and be just as happy. I'm just looking to enhance overall performance of the engine and maintain reliability.
