Aches, pains and remedies
 

So I picked myself up a set of Moriwaki rearsets, which I think are about heavenly, really, not to mention gorgeous, but for the first time ever, nothing else was sore except my hip flexors. I could barely sit still they were just -aching-. Finally hit a few stop lights that allowed me to stand up fully, but could this be because the rearset is to low, perhaps? Thoughts/solutions would be welcome.

So you picked up the set that came up here recently? Dog! Nothing more, congrats.

I think it's your hips getting used to the raised rider position. Mori's are +1" right? at all settings. Enjoy, they would have been mine. But that's like girlfriends.

Because you are +1 you need to scoot your ass across the seat a bit farther than you have been in turns. This is what's working your hips. I hope your suspension is up to the game cause these are some good race pegs. If your suspension set is off this will also contribute to you having to muscle the bike around what should usually be a smooth maneuver. Stock shock at this rider attack is lethal.
