One tooth on the front = 3 teeth on the back.

What's broken? Are you interested in a used stock one?

I don't know how to tell what is broken exactly but if yours works, then yes it's something that may interest me. I know the back of the speedometer is cracked, but it's always been like that and very jumpy. So I don't know if it's the actual unit that is not functioning properly or the sensor or cable on the tire.

I know the lights work and everything, just not the speedometer or odometer.

A guy named BMWHD who along with Deej were the founding members of the KLX250S board here confirmed that the one made for the Honda XL650 would fit our bike perfectly, so that is what many of us oredered. True to his words, the sprocket fit perfectly as if it was made for our bike. The front is a biotch to take off and I had to use a impact gun to take it off, unless you have a friend who is at least 200 lbs that can sit on the bike with his foot on the brake.

More teeth on the rear has the same effect as less teeth on the front. It will give you better acceleration at the expense of the engine rpms being higher at the same speed. If you go more teeth on the back, you will have to get a new chain; if you go one tooth down in the front, you can keep your current chain.
Just checked my current set up as I bought the bike used and I counted the teeth on the front sprocket and I'm pretty sure there were 13. On the back sprocket, there was a number 42 so I'm assuming that it means that i have a 42 tooth rear sprocket. I checked the current tire size as well and it has a 110 on it right now.

What's this mean for me? What changes should I make?

Sounds like that means someone switched out the stock front 14 tooth to a 13 tooth. That's probably good. If you're doing lots of street riding and want to "gear up" so that it runs at lower rpms at speed, you could switch to a 14 tooth front. Your setup now has more torque at the rear wheel than the stock setup.

On the speedo, try to narrow down the problem. It may just be the cable, or the gears in the front wheel, or the speedo display itself. See if you can narrow it down before getting another speedo display that may not be the problem.
