Question about chain #

[toxicmammoth]

I just got my 80cc kit today. I'm working on a funky jackshaft idea so I won't be using the out of box configuration. I have a question about chain #.

I should know this but I'm asking the forum. all my go karts & minibikes were #35 chain. I need to order a sprocket or two so I need to double check the following..

1. Bicycle chain - what # is it - <maybe #41???>

2. The chain that come with the 80cc kit - what # is it. <me thinks #40>

Any help here would be great!

Thanks!

Most (all?) the kits come with a #415 chain. (from the dax site)

I went to buy an extra master link, and all I could find was a 35, 40, 41 ect....luckily, the bike shop near here sells these engines pre-mounted on new bikes and he had a spare #415.

I did a google search and found 415 chain mostly from moped shops online.

My old Honda 90 used a #428 and another I had a #420

Confusion sets in......

Can someone offer some clarity here?

Here is a small amount of info...

If you go to your local bike shop that has decent BMX stuff you can find chain the will be more than beefy enough. They should have several different style too...some even have an ALL half link chain.

This site even sells 415 size chain

I hope this helps.

Thanks!

I didn't even know there was such a thing as 415 chain!

Thanks for the links as well! I came across this one once I kinda knew what I was looking for.




Chain - Pitch - roll width - roller dia
bike- 1/2 - 1/8 - 5/16
415 - 1/2 - 3/16 - 5/16
420 - 1/2 - 1/4 - 5/16
#40 - 1/2 - 5/16 - 5/16

So the roll pin diameter is all the same, its just the width - the distance between the inside of the plates that differ.

Well on my Schwinn chopper, the chain was too short and we replaced it with #41-1R works like a dream!

Still awaiting my "test chain"....I ordered it from an eBay seller and it was to be shipped Priority mail....I got a sad sack story about how they have "too many customers" and not enough staff! Still waiting after 12 days.
