What front sproket should I use?

[AZMarine]

I picked up a local guys complete rear end and he gave me his chain with it. I'm new to ATVs but I noticed the rear sprocket he gave me is considerably bigger than the stock one that was on there. I count 40 teeth on the sprocket that was on the bike and 45 on this new one. Which front sprocket should I use with it? When you + the rear, what does that add? The chain fits perfect but I just don't want to end up with some combination that kills my power.

45 is tall torquey sprocket

a 15tooth front would put it back closer to stock gearing, changing the front sprocket 1 tooth is comparable to changing the rear 3 teeth, whichever way you go

when you go up teeth on rear, its the same as going down teeth on the front, and vise versa

if you ran a stock (14) front with that 45 rear, you will be shifting a lot more, gears will be shorter, but torquier,faster revving you could say

the one problem i see with such a large rear, will you be able to run a skidplate with a 45t rear? a stock 41t comes pretty close

i would run the stock rear, and buy a 13t front, cut the plastic on the stator cover so you can access the front sprocket easiler, then you can change between the 14 or 13t front depending on what you are doing or where you are riding or what you prefer at the time, cut the plastic off then you can change the front sprocket in minutes without removing anything but the chain

I don't even have a skid plate for it yet. It's a +6 Metal Tech, can you even run a skid plate with an aftermarket chrome moly swinger?

 

Thanks for the answers guys, that's the info I was looking for.

Front sprocket- more teeth=less torque=longer gears

Front sprocket- less teeth=more torque=shorter gears

 

Rear sprocket- more teeth=more torque=shorter gears

Rear sprocket- less teeth=less torque=longer gears

 

Stock gearing- 14/41

Depending on where you are riding depends on what set up you have. I ride strictly dunes but because I have a built motor I run 14/40 and have no problems. Before I built my motor I ran 13/41 for more torque in the sand. Correct me if I'm wrong but 3 teeth in the back= 1 tooth in the front. Hope I helped!
