    You have to shorten the chain. Did you do that already? Look for the master link which allows you to undo the chain, then, using a chain breaker, adjust the length of the chain, and then use the master link again to close it up. It's easy. Just make sure you don't make it too short. Measure twice and cut once!

    I highly doubt that the master link by itself is causing your problems.
    Can you post pictures?
    If it is loose only in one spot, it could be that the chain links are too stiff in one area of the chain to let it flex properly, or it could be that the rear sprocket is not centered on the wheel.
    Also in some cases the sprocket teeth on the engine and/ or rear wheel have a bit of manufacturing burrs on them and this will cause the chain to ride up on the tips of the sprocket teeth instead of down in the valleys like it should.
    Carefully watch the chain as it travels around both sprockets to see if it is doing this.
    You will have to remove the engine sprocket cover to do this on that sprocket.
    If it is happening, use a file and file down the teeth on the sides only, not in the valleys to very slightly thin the teeth so the chain will slip onto the teeth easier. Usually you do not need to do the whole tooth length, just the outer ends.

    Is the sprocket on the rear wheel perfectly centered, if not this will cause the slack at one point and then it will get tight at another.

    Rear sprocket must be centered or you will have big time trouble....

    I purchased a #41 chain but it did not come with a master link, I have a chain breaker but the pin does not push thru all the way. Anyway to reconnect without a master link?

    A master link is the only safe and reliable way to go. Any shade tree methods can put you and the bikes health in jeopardy.
    FWIW, alot of chain breakers will not push the pin clear through the link. Sometimes you need to push out the 2 pins on the link you need removed and take off the side plate to slip the chain apart.

    Use a pin punch to tap the pin the rest of the way out.

    yes it will work...now what chain are you using on the motor...415 or #41...i use both and they work on the kit sprockets...the one you ordered for the tensioner is for#41 chain...the chain is wider than the 415...so make sure when you get your tension bearing the chain fits it...Dennis
