I have done a lot of experiments and have found some things that consistently work and some things that actually hurt your mileage. I am going to describe here what I have found that works and what doesn't work. This is all based on experiments I have performed on my Geo Metro XFi.
I have been riding my DR650 for awhile now and I decided it was time to do something about making it more comfortable. There are very few options for highway pegs on the bike so I decided to try making my own.
For anyone interested in Mobile Blogging I have found one program that works pretty well from a Windows Mobile based phone. Diarist is a very nice app that lets you write a post on your device and it will automatically post to your WordPress site. This is useful for anyone wanting to be able to write a post on their Windows Mobile Phone or PDA then post it without having to use the web based forms to edit and add your posts.
The Innovate LC-1 sensor is pretty expensive for the intended usage so if you drive a lot or your vehicle gets really bad mileage it might be worth it but if you do not do either then this will be of limited use for anything other than bragging rights.
