need new chain????

Can some one tell me what size chain I need for these china girl motors??? I thought I saw some where 415 was the size Then when I looked some where else on the forum it said #41. Which is it??

The 415 chain comes with the kit .

I use 420 chain because it was the only chain available at the time.

Number 41 works very well.
A bmx chain will work if you grind down the sides of the sprockets.
I have used all of the above chains to destruction.
And bought some more to use.
Quartz dust destroys chains fast.

Number 41 roller chain is cheap and easy to find locally. Works great and stretches less than the 415 supplied chain.

You can easily find master links at lowes/tractor supply co. for cheap. I got my chain at TSC but have found them at my local Lowes as well.

Get a #41.
