I have a 70 tooth #35 chain sprocket. What is the equivalent using a #40 chain? Is a #40 chain stronger? Thanks for your help.

Whatever maintains your current ratio.

Is a #40 chain stronger?

If it's quality chain, yes.

What sprocket do you have on the engine side? If you had a 72 tooth on the axle and a 12 on the engine side that's 6:1.

A 70 tooth #40 sprocket is identical ratio...am I missing something?

The difference Between the 2, is the 40/41 is bigger... so the sprockets will be a different OD..

If you meant the "equivalent diameter" to your 70-tooth /#35-pitch sprocket:---> A 52-tooth / #40-pitch sprocket would be very close to the same diameter.

If you wanted to stay with the same overall gear ratio when changing over to #40 pitch, your clutch (or engine drive) sprocket would also need a different number of teeth... We could help you figure this out if you tell us how many teeth your current #35-tooth clutch (or engine sprocket) has?


Here's a couple charts showing the diameters of various #35 and #40 sprockets:
