Sprocket set up

[GGcastro]

I’m running a 421 on 110 with a +6 swingarm and 9 paddle hauler 74 rollout what sprocket set up should I run to be able to take off in 2nd and still have top end?

Probably not much more than stock. How much do you weigh? What's on there now?

I weigh about 130 pounds and right now it has a 15/41

Have you ridden it yet? It's likely going to be a test and tune situation.

Hello all, 

I think this would be the best place to post this but let me know if it should go into another forum. I was cleaning my rear sprocket (Sunstar 3679) and I noticed a crack between the teeth that runs through to both sides. I don't really think it's the best idea to chance using it anymore, probably best just to get a new one. 

What is the best sprocket on the market these days?

Go with new sprockets and chain from Driveline.

Awesome, and thanks for the quick response. I'll take a look at them links now.

What do you think of JT sprockets? Also what do you think about steel vs aluminum? I imagine the carbon steel would hold up better in the long run, but you get the benefit of less weight with aluminum.

Steel will last way longer. What’s wrong with the Driveline?

Oh nothing, I just like to see all of my options and understand the difference in materials, heat treatments, coatings etc. I'm a metalography/materials technician so I guess it's first nature to look at those kinds of things. 

Why would someone choose aluminum, looks?

I used the aluminum rears when I was grudge racing. Just less rotating weight.

Go with the Driveline. You won't regret it.
