    'nother question ...I have china doll standard 80cc. I want to get the correct chain break tool, but I do not know what type of chain I have. I think the consensus is my chain is most likely a #410. I don't even know what that means.

    Is there a way to tell, without question, what type of chain I have? Perhaps measuring ...but what to measure?

    You have #410 chain...

    The pitch of the chain should be 1/2" between teeth to confirm this

    #410 is in the same family as #415 and #41... all the same pitch, just differing widths

    No You probably have a #415 if it's a kit-
    although I think a vendor or two here still may ship a 410

    They are all the same length of link

    the dif is the width:

    a standard cruiser or one speed chain is a #410 and 1/8" wide- this is the most narrow point INSIDE the links

    a standard derailleur is 3/32 wide

    and the usual kit chain imported is the 415- 3/16 wide at the most narrow inside point
    see my thread about the new 415 chain I found- to me the perfect solution

    you get the 415 margins of error to keep from derailling- but in a chain that doesn't weigh much more than the 410 cruiser chain-

    Of course weights vary otherwise even in the same width depending on the quality of the chain

    back in the day- road racing through the seventies- I used to change a chain several times a season- they get gritty and they actually stretch with use-

    the basic rule has always been you cant run a new chain on a worn cog, and vice versa because it wants to skip- on a deraileur chain at least

    A road bike had a 5 cog in the back when I started and then went to six- but the chain still stayed the same size-
    after that they got even more exotic and went to seven, eight and nine speeds

    Fine- but too exotic and the chains then got too expensive- for something that has to be routinely changed

    if you have a skinny bicycle type chain like the new Grubee Skyhawks have, any chain breaker from a bike shop will work.

    if you have a fat chain that looks like it should be on a motorcycle, some bicycle chain breakers will fit, but you'd be better off getting one designed for a motorcycle. Harbor Frieght has one for around ten bucks.

    For my kit chain, I think its a 415 I got the chain breaker from motorcycle shop cycle gear. And I love the way it works.

    Chain Breaker

    Its a bit more expensive, but was worth it. I was able to push the pin out, adjust, and push pin back in. No master links.

    Here's one under $19 shipped- haven't tried it
    http://www.ebay.com/itm/motor-motor...992?pt=LH_DefaultDomain_0&hash=item4157c32cb0

    As I wrote in the thread linked above- you can also get a cheap Bell breaker to work- if you take out the middle supprt ridges with some pliers, and you have to start it partway through with some channel locks or a hammer, pushing it back in.
    about $7 at wal Marts everywhere
    Harbor Freight's is out of stock, backorder, $10 BEFORE shipping, and has no handle

    I got the same tool from BGF on ebay . Looks solid enough. BTW, my chain is #415. Thanks to all that posted with your help and input. As always this forum kicks a$$.
