I have 2 questions for people out there with experience, please: 1. I dis-located my knee 6 weeks ago and it's still not well enough for me to ride without pain. Has anyone tried DMSO for an injury such as mine, and does it speed-up the healing process? 2. The temperature where I'm at has gone down from 80's to 50's and it is affecting the performance of my bike. Do I just adjust the fuel screw or is this going to cause me to have to re-jet my carb. again. Thank you in advance for your help.
