[QUOTE="kleake, post: 1189276, member: 19825"] Ran PR3's previously, installed a new PR4 a few months ago, had the forks rebuilt due to a leak. No issues through all of that, but I put on a new PR4 GT and now the rear feels loose and wiggly. I got my first ever real wiggle like you see on those super high speed races when a bike comes out of a corner hard. I was going about 50 on an entrance ramp with a slight right hander. Not pushing the tires at all, but it caught my attention. It feels like I'm running over tar snakes when I turn out of parking lots, but there isn't any tar snakes. It seems to do it worse turning right, but it does it both ways. At about 45-50mph, in 3rd, back off and get back on the throttle abruptly and it feels like the rear is pushing to the right, the back off and it settles back in. It does the consistently, but just started with the new PR4GT tire. I double checked my axle nut and other components and didn't find anything. I never felt this before and I've been through 3 sets of tires on it. It's squirmy enough that it really has me concerned, and it doesn't feel like it's just a new tire breaking in. Any ideas?
