New to the forum, but not new to quads. Recently purchased a 2004 Sportsman 700 that has less than 700 miles on it. It’s my first Polaris machine and first 4-wheel drive. It’s in great shape as far as I can tell and does have a professionally installed 2 inch lift that was put on recently with a new set of Gator tires. Machine definitely has not been abused.

Question is that whether in 2-wheel or 4-wheel drive from a dead stop the machine is very jumpy. A little worse on hard surface than on dirt, but about the same. Feels like somebody is hitting you in the back with a ball bat it is so jumpy…catches than doesn’t. It honestly feels like something in the drive is slipping or jumping and it feels like it comes more from the front than the rear, even though the AWD is switched off. Also, it seems to require what I would consider excessive RPM to even get it to move, but maybe that is part of this system I am unaccustomed to. Once underway it appears to be fine, although I have not had it in the mud/extreme conditions yet.

Any ideas what this is or what may need replaced/adjusted? I’ve had it up on lift and all of the driveshafts appear fine.

Any help or advice is much appreciated!
