Shock mod update;
Put 65 miles on the bike last weekend, over very rough Texas panhandle canyons and open range. Bottom line, could not be happier with the ride. Everything from rock crawling, to open country running at 15-20 mph, never had to leave the seat (or get bounced off of it). Smooth, comfortable ride sucking up every hole and rock it hit, without feeling it in the lower back or kidneys.
Learned that the Foreman is basically a Billy Goat in 1st gear crawling up steep, loose rocky terrain. The Polaris bikes needed rpms and tires spinning to make the same grades that the Foreman just walked up.
The bike never jarred me, or felt anything but soft without feeling loose. The extra couple of inches of travel are really nice. Had no issues with the swing arm, drive line etc. Only thing left to do concerning the ride quality is get rid of the 17 year old front shocks and swap in a urethane bushing in the lower, rear shock mount. The auto shop rubber bushing wasn't the best fit, had no inner steel sleeve and is settling a bit. Think I will swap out the ball joints and tie rods ends while I'm at it, front end needs a little help.
