I decided to enjoy a 70-degree, late November day by taking a 100-mile ride. Planned to ride from Canyon out to Vega, then up to Boys Ranch, then back down thru Amarillo to Canyon. Left at 3 p.m. wearing my warm weather gear (Olympia mesh riding suit and Held Steve Gloves). About 25 miles from home, I could easily feel the wind switch from the West to the Northeast and over the next 10 miles I saw the temperature gauge on the dash drop from 75 to 58. Not terribly frigid, but when you are dressed for warm weather it felt awfully chilly. So I aborted my planned route and once I got to Vega I headed South instead of North and rode down towards Hereford. Within 15 minutes the temp had climbed back up to 68 and I was warm again. That lasted until I was bout 10 miles West of Canyon and heading for home, when I hit the front again. Regardless, it was a nice ride....also a good shakedown after having replaced the spark plugs and air filter. I'm always leery of a misfire from coil packs not being re-installed correctly.
