When I rode my '05 950 back to back with a '10 990 Adventure (R mapped) the difference in power felt huge. My '05 is well sorted and taken care of but the FI 990 was so instant and crisp if felt like more power all the way through the rpm range. This was before the days of the CPR filter as well. I'm sure that will boost the power of a 990.
This will be one sweet build. For a bike that will see most of its miles in Baja I cant think of a better machine out there!! Can't wait for you to share the write up.
