It sounds good.  Good luck with your PT on the wrist.  How did you break the wrist, a fall?

negative, I punched the wall out of anger one day. The lady got under my skin.

I recently purchased an exhaust system for my bike, its the first nice system i've bought for this since I've owned it. It's a used set up off eBay auction.

Just under 400 to my door from California, its a mac header, cycle x reverse cone, and a mid section (unknown) If this set up was new, the mac header is over 300 and the cone alone is 120....plus i didn't have to figure out the fitment and it was bolt on. Im really excited and not used to seeing any kind of shiny header on my bike, let alone a fancy looking reverse cone lol. The yellow bike pictured is the one it came off of. Im waiting for a new shoria battery so I haven't heard this set up yet.

How you guy like the top of my fork tubes? lol.

Assuming you haven't already done so, when you switch to the Shorai lithium-ion battery, you should upgrade to a solid state reg-rec that is specifically made to work with a lithium-ion battery. 

Standard solid-state reg rec units have had problems with some lithium-ion batteries leading to runaway charging and lithium-ion battery fires/meltdowns.

Thank you for the reminder, luckily I have one brand new in the box waiting for this battery to arrive. I bought it last year and never installed it.
