Ok now silly question how do you know that your in 4wd all the time,other than the light.The only time I could tell when it went into 4wd was in the sand going fast,I could feel it kick in once in awhile and straighten out.Any other time as when climbing rocks I never have felt it kick in.I just know it's there when I need it.I would think just haveing the light on wouldn't mean anything other than you have bypassed the switch,you still must spin rear wheels to engage.Maybe I'm wrong and I'll stand corrected.CM

You could not have copied the post on how to do the AWD mod any better. You wrote it almost word for word. It looks like my original post.

The purpose for doing this modification on an Xpedition is so that when you are in reverse you do not have to hold down the overide button to get AWD. By doing this mod the switch works just like normal. The only difference is that the bike does not have to be in gear to get power down to the hubs.

 

Put more air in either the back or front tires. I forgot. which one worked. So that way when the back tire has 3 psi and the front have 9 psi. The back tires are spinning faster than the front. ANd the more you run in the front the easier to steer. I have never popped a tire or has it came unseated. Why on a sp500 does the left front tire wear faster than the right?

 

Hey everyone, thought it was time to bring this subject back up. I have been wondering if this modification is possible. If so, it would make the sportsman the perfect quad for me. I would then have the option of 4 wheel engine brake and the option of having my front wheels "pull" me places instead of always having the rear ones "push" me everywhere. I ran a search and found this thread and thought that I would comment. First of all, I am no electrician and have a hard time reading schematics so much of what has been said is greek to me. It appears that the consensus is that it is not possible, but I ride with a fellow who owns a yamaha wolverine. I call it a polverine because he yanked out all the front 4/3wd stuff that came from yamaha and installed a polaris differential, axles, and hubs. He now has selectable "true" 4wd on a yamaha wolverine. Another fellow we ride with installed a 2001 or 02 kodiak differential so that he can select 2wd, but when in 4wd he still has limited slip. But the guy with the polaris setup has 2wd and true 4wd when he activates a switch. According to him it stays locked or activated until he turns the switch off. His bike is not even equipped with a speedometer so any type of wheel speed sensing has nothing to do with it. He told me that the hardest part of getting it to work was getting the spring in the hub adjusted so that centrifugal force would not cause the hubs to sporatically engage at higher speeds while in 2wd mode. I would settle for the option of being able to keep the front end locked (after spinning rears) until I turned it off b/c the main reason I want the option is 4w engine braking w/o the whole back up hold button down and then hope that both hubs stay locked while going down the hill. I have read the debates and the opinions but just wondered if this polverine set up might turn on some light bulbs for you polaris gurus. Like I said, I'm no pro in this area, but saw the polverine setup and would even settle for that as a third option. Then I would have 2wd, 4wd on demand, and 4 wd locked (even if I had to spin the wheels once to get locked up).
