My 07 SM purchased new in Feb 08 has +20k on the odometer. When I take 'er out,it is usuaaly for a 300 to 500 mile romp. My riding fantacies are to travel well beyond the California state line. What modifactions can this group of wizdom wrenchers suggest to increase fuel economy and range and still maintain some performance. I want the option of riding 200 miles between stops and traveling faster than 50 mph. I am currently running with the Triumph off road pipes and therefore, I know the mechanic changed the needles, but am not sure to what size. I am due for a chain and sproket change. I am considering a Tour Tank addition to the rig, but I waiver on the space it'll take up. It's cheaper than a custom tan by a local shop.
