Drive sprocket too large?

[pghewins]

order DID 415s

I seem to be having the same issue. A 415 bike chain, purchased from my local motorized bike dealer.

I have a dremel and can grind the teeth down.

Do I grind them flat so it's shorter. Or at an angle to make it pointy.

And do I grind all teeth. Or just the one I'm having problems with?

Also how can I get the sprocket out so I can work on it?

Cheers
Kevin

put the dremmel away and buy the correct chain

Thanks for the tip pghewins. Good to know. But I've already dremeled the sprocket lol. If/when this sprocket fails and needs to be replaced I'll be sure to follow your advice.

Anyways, had a lot of drama with chain breakers the last 2 days, but after being advised to buy the wrong chain breaker by the local bike shop was refused a refund for signs of being used. So I got 3 chainbreak tools now, lol, only 1 will suit my needs.
And after pushing my first rivet through, the pin got stuck in the bloody chain lol.
So after alot of fiddling around I got the pin back out, and ground it down with the dremel, before trying again. Success! I was able to add the 2 links I needed and close the chain with a masterlink.

Frostic, where did you get your tensioner? I love it.
The crappy one I have doesnt even go low enough for my chain. In the meantime I may need to add some more links.

often the drive sprocket is one that was stamped out flat rather than machined with pointy teeth - with a 415H chain, the rollers are a bit wider than regular 415 chain so one needs to file or grind the tips of the teeth a bit

I've seen folks get away with putting chain on REALLY tight and riding carefully until the chain stretches some, but I always grind the teeth when I get one of those sprockets.

Wow Crassius you will be hearing from me Ha!!!

Everything you have commented on the 2 stroke I am going through right now I was up all night with that damn thing now I got to pull off the gear and file down because like you said its stamped and I got a 415 chain and its more than likely gear for 410 I got it all ordered but how can I space it out a little for alighnment I know theres s**t you can order any ideas I need to bring gear out about a 16th

I just found this website today I build drift trikes well I hot rod them not bending frames or nothing when I learn how to get around a little better I will post some pics

put the dremmel away and buy the correct chain

You would think they would not send you a 415 H chain and a motor with a 410 gear In the same box everybody doesnt know that they must have got a deal on that chain
