Chain links

[Succubus]

Quick question, y'all. I am going from a stock 40-tooth rear sprocket to a 52-link rear sprocket. Stock chain length is 104 links, according to the book (the stock chain is long gone, so I can't count the links. The bike came with no chain). My new chain is 120 links. How many links do I need to cut from the new chain to make it fit? Should I cut it to 116 links (104 stock links plus 12 extra teeth? When I check the chain to the bike now, with everything loose, it seems like I could easily cut six links off the new chain and it would fit, but I don't know how that math would work. Thanks for your help.

hang the chain, see how much overlap you have and cut off the excess, and remember you can always cut off more, but it's much more difficult to add links......

yea, i do it like this, cut one off at a time and keep chacking. its a long procdure, but i never come up short.

plus once you use the chain and it may stretch alittle, you could sill cut links out.
