    We’ve been using GPS exclusively for the last several years on all three of our karts. BTW, we find the MPH and track mapping extremely helpful. I really don’t see the need for both.

    From what is sounds like, you are blocking the air at the pipe. Pull the pipe and put a plug in the exhaust manifold. You can get one at the hardware store. I use the rubber plug with a wing nut on it. Put it in the manifold and tighten it up. A stethoscope is good or a length of tubing for checking. You can also spray simple green on critical areas and look for bubbles. Check around the powervalve plugs. Those o rings are easily damaged when sliding the plugs in. Crank it up a little higher and then log the drop per minute.  You are definitely on the right track.

    Those of us who knew Carol Smith or followed his “Prepare to…..” books wouldn’t hesitate to use the string method. It’s a bit slower, but if you have any questions about your chassis, it’s a great way to go. Not many people verify that they are starting with the front wheels aligned with the rear before setting toe and verifying ackerman.

    For future reference, use the flat end of a small drill bit.

    They will wiggle right in to place.

    Check the alignment from the engine driver to the sprocket.

    Check to see if the sprocket carrier is bent.

    Check to see if the gear is bent and whether the two halves are mating correctly.

    No. Fuel accumulates in it and part of regular maintenance is to wash\blow it out. I don’t know where your pump is located, but check the line for cleanliness. This is the one that goes from the nipple on the side of the reed cage to the port on the pump. This sends the pulse to the diaphram in the pump to pull\push fuel. Check for a nice short routing of the line and usually you want the pump higher so fuel can drain back. Keeping it clean will make fuel delivery more efficient. Also make sure there is no kinks in it and that you are using a fairly thick walled type of tubing.  Some people use the one with the braid in it, or Motion-Pro which has a super thick wall to prevent kinking.

    Be sure to clean out the pulse line. When you look at the other pump, check the pulse side for being full of fuel.

    You need fuel, spark, and compression. Check the compression and make sure you do not have a broken reed. Even if you have someone pull it in sixth gear and put your thumb over the spark plug hole. Be sure to ground the plug. Next check for spark. Pretty hard to see on a CR125. Ground the plug and cup your hands over it while someone spins the rear wheels. If you have that, then the box, stator, coil, and grounds are good. The last is fuel. Is the plug wet or dry? If its really wet, you also may have the bottom of the crankcase full of fuel. Ground the plug and spin the motor with a strap off of the wheels with the plug out. If you are flooded below, you should see a mist coming out of the plug hole. If so, put in a dry plug either new, or known good and let it go. You can also try turning it over on a start with the accelerator all the way down. If it catches, be sure to let up. CR125’s are really reliable and should not be hard to start. Check out some of these items and report back.

    Some indicators of Mod 125 are:

    Non-OEM ignition

    “O” ring head

    Spacer between the cylinder and the block

    V Force Reed Cage

    Not definitive, but upload some pictures

    Good plan. We run the Shark Shifter one above the carb and have no problems.

    What parts are you looking for? The Energy kart that I had was pretty “European Generic” as to parts. I believe it was made by Parolin. Russell Racing at one time had a kart with the same braking system. Beyond that, I can’t think of too many parts that cannot be substituted.

    Aaron, I’m so sorry. I transferred your post to Badger Kart Forum-Everyone will keep their eyes out. I would suggest you post some pictures if you have them.

    Funny you should ask. I’m testing a bypass Thursday and Friday.
    News to follow.
    Many years ago we used the inline one and didn’t like it.
