Test ride today 20 miles. I haven't added my K&N filter yet as it hasn't arrived so I was expecting perhaps a rough tickover. It didn't happen! Tickover is lovely and smooth, pulling through the gears is noticeably better with a lovely boost around 4000rpm which seems to go on forever ! At one point I must have reached the rev limiter in 3rd as it briefly cut out , I think I was well into the red range but at that point is was still pulling well. In short this upgrade is just brilliant, the bike (R1100GS) has been transformed and given it a new lease of life. This coupled with my new Remus system is going to make the summer more enjoyable .
The chip was relatively easy to fit, I made one mistake by seperating the bottom plate and not the top as instructed! No big deal just wasted some time. Start to finish was about 90 minutes I think. Well done John, another happy customer ��
