Sprockets

[PeteJ]

Are these sprockets universal for chain size? Every site I check just says sprocket 20 bucks but no info on what size chain it uses. Right now its running 415 chain and try finding a centrifugal clutch that uses 415 chain its pretty hard and none in stock.
Another question can some one tell me in an easy to understand chain sizes that will work on 415 sprockets every were I look just leaves me confused or again anything that is supposed to work they dont have a clutch for it. Better yet maybe someone knows better places to buy stuff that I havent found yet. Thanks for any and all help. PeteJ

Here’s a thread I did years back that may help.

Chain size chart

I thought this chart would help some new to M/b building to select a better chain. Chain Strength & Dimensions Chain Number Pitch Roller Diameter Betwwen Inner Plates Pin Diameter Average Tensile Lbs. per foot __#40 (#425) 1/2 .312 5/16 .156 3,700 .41 __#41 1/2 .306 1/4 .141 2,000 .27...

I run either the 415 or 41, the 41 works well if you have enough clearance. Some people have reported that the 41 hit the gearbox as it turns, I’ve never had that problem.

All of the early sprockets were thinner for the 410 chain, most all kits came with the 410 when I started. I wouldn’t think you would find many 410 sprockets now.

Thanks for the info. Your sprocket info is by far the best and most easy to use plus it makes it a lot easier to know what I have to work with

I have plenty of room cause no gear boxes anywhere near the chain. Never really paid attention till now but there is a lot of side by side slop in the 415 chain on both sprockets. Is that common? looks close to a 1/4 inch

The rear sprocket looks like it was made for the #410 chain, if the front sprocket is the same you could run heavy duty 410. Don't go cheap on chain, you need to buy good quality.

Once had a person who had a 410 in the rear and a 415 in the front. So I switched out the front engine sprocket to a 410. Heavy duty chain is a must.

My problem now is finding centrifugal clutches that you can use with 410 or 415 chain. 99% of clutches on ebay or amazon are made for 420

Can you replace the sprocket on your clutch?

420H chain with no O-rings works fine on my bike,I don't see why it would not work here

Never even looked into that so super thanks for that info. I do know it comes apart cause I just bought snap ring pliers to check how worn the clutch is. Anybody ever use this brand of clutch?

I have searched and searched the internet and typed in a million different phrases searching for bike stuff and this one has never popped up. Really maybe only 1 or 2 bike places at best. This is a good one Thank you very much
