How do you remove the front 22 tooth sprocket on a 96 Polaris 425 4x4

Technically yes you can, HOWEVER!! The 23x8's are taller, thinner tyres so they might affect your speedo reading and handling if they are not a standard Polaris size. The front end will also ride a tiny bit higher than the rear end. If you haven't got the original handbook try contacting Polaris directly or a dealer with your vehicles details and ask them what sizes are recommended for your ATV.
ATV tyre sizes translate as follows... a 23x8-10 tyre will be-
= 23 inches in diameter measured all the way across the widest part of the whole tyre.
= 8 inches across the width of the tread of the tyre.
= 10 inch diameter of the actual wheel rim.
22x11-10 is 22 inches tall, 11 inches wide on a 10 inch rim.
23x8-10 is 23 inches tall, 8 inches wide on a 10 inch rim.

On 2002-2004 models, the fuse panel is located on the front frame member underneath the front fender cover.
The center cover under the front rack is removed to gain access to the fuse panel as well as the radiator.
I find it easier to unplug the headlights and remove the front rack for this.

check the hub fluid?

I'm in the UK and not familiar with your particular vehicle..
However, the front gearbox as you call it is probably a transfer unit/case. This transfer case takes power from your auto transmission and transfers it to the front wheels.

You can remove the front propshaft (drive shaft) from the transfer case/front differential and make your vehicle 2 wheel drive. This, supposedly, gives you better mpg.

Could be a carb issue, did you set your timing correctly?

pull the sensor out on flywheel side turn the engine till the v lines up with that hole set all 4 lines on cam sprockets straight across with i and e up and the lobes facing away from each other


Ignition timing is done by the ECU and can't be adjusted; camshaft and balance shaft timing done during engine build-up

14 - 41 = 2.93 ratio
15 - 46 = 3.06 ratio..
6-7 links.. you need to move the axle all the way forward when installing a new chain... (it will stretch!) moving the axle all the way forward gives you plenty of adjustment later!!

Usually a slide HAMMER is required to remove an axle.
Check Princess Auto for a SLIDE HAMMER

Pull cover & remove nut after bending down locktab.Replace sprocket with new. Retighten with blue loctite on nut & refold locktab so it can't come loose.Readjust chain slack to 3/4 " in the middle of chain. Retighten rear housing bolts.
