Hey eveyonr, You're all probably getting tired of my posts, but hey, they're sensible questions, I think. Ok, I was thinking of changing my sprockets from the stock 16/40 to something else. I was considering the 17/37. what else does everyone use? I need something that will help a bunch in top end speed, not loose a ton of acceleration, and still not kill me on bottom end. I know grer Rowe used 17/37 on his baja. Is there any gearing changes that can do all this, or will I just have to change ratios when I drag race?

Will my holeshot suck? what different ratios are for different things? I was thinking of dragging some cars at the local drag strip, on free drag nights.

Oh yeah, and does anyone know where I could get a set of worn out tires, for asphalt dragging? I don't want to spend to much, just something to use

Adam, the 17/37 is great for wide open desert racing. I used to run it, but if you want to drag/hill shoot, you need to go in the opposite direction.
I'm currently running either 15/41 or 16/41 depending on how steep the hill I'm racing is.

Where can you get a 14 tooth front sprocket? I was looking to get one for trails and hillclimbing.

If anyone wants to buy a 37 tooth sprocket I have one I'd be willing to part with. I only had it on for a week. It wouldn't work with my current skid plate and I really didn't need the top speed as much as I thought. It was nice not to hit the rev limiter in top gear though. It's just laying in my garage now.

Ok, what I want to know is what kind of sprocket combo do I need to used for my type of riding, which is: Jumps, drags, trails, just normal sport riding. I need some more speed, but no lost acceleration, or low end

MarkyNark after using your gearing calculator I think I will go to a 15/43 set of sprockets. I have 15/41 now and with the 22 inch tall tires I have now my top speed is 83 MPH. I due not go 83 MPH through the dunes. With the 15/43 set up my MPH just goes down to 79 but will I get better pull up the hills.
