    I was informed a torque stop would be a good thing for me to invest in. When i searhced the site there was 3 threads of which none had any helpful info on one. What is this, where can i get it? how does it look? Can i make one? Thanks XD

    in my opinion, this is not a thing you buy, but it's a thing you do.
    to "torque stop" anything with an engine, you kill the engines power but leave the clutch engauged (clutch lever released).
    this will used the friction of the non running engine, to slow the bike down.
    the piston will still be going up & down when you kill the ignition and will slow the bike down.
    all you do is hit the kill switch and hold it in with the clutch lever released so the engine doesn't start back up.
    the piston will keep moving because the rear wheel is still moving, but the friction from the piston going up & down will act as a brake.

    I have no idea if this is ok, or if it's bad for an engine tho.
    I personally never do it.

    OP so someone says you should invest in a Torque stop .... Um I presume you asked them what it was .... what did they say?

    They meant using some kind of metal bracket that goes between
    the right side of the seat post and the 2 stroke motor case so
    your motor can not twist towards the left motor chain side and
    cause chain alignment issues or derailment.

    If not firmly attached the 2 stroke motors have a tendency to
    lean to the left although I have never seen a 2 stroke that used
    a "torque stop" and I have seen and ridden a lot of bikes.

    So yes you can make one.
    I think it was Al Fishermans idea and he had a picture.

    I came up with the idea because I only torque my mounting stud nuts to 50 inch pounds (I use a inch pound torque wrench on ALL critical fasteners). On a few frames I have had issues with the engine twisting on the tubes (ever so small) and the chain wasn't aligned correctly. To combat the problem, and not to over torque the engine mounts, I came up with this. Easy to make. All that it is, is a 90 degree small bracket, sold in ALL hardware stores. Enlarge one hole for a 6 mm bolt and cut off any remaining excess leg. I used the extra nut next to the clutch housing because the scrap I had at hone wasn't long enough. Here I used a piece of angle iron. If you want one, and don't have the tools, contact me...they are inexpensive. Tools needed are a drill and bit (for a 6mm hole) and either a hacksaw or grinder.

    Ron, this is a fantastic idea. I've seen this in the past, but really didn't think mine was really producing enough torque to be an issue? Now, with mods & torque pipe...................YOU better believe it's needed!~

    looks interesting from the tiny thumbnail, but my browser can't seem to get to that full sized pic on that beta ver of photobucket

    I can't tell what part of the motor this is hooked to, or how : (

    can you post a couple pics here or on or some other hosting site that show more detail?

    Workd for me :) the pic does not show what the bracket is pushing against only that it is attached to a bolt on the motor.
