Hi Golfgeezer.
After you and the 'S' have settled in and you've done the Zero=Zero procedure to balance and synchronise the throttle bodies, and before you do any other performance mods, fit the 1100/1150GS intake tubes and then see how much more performance you want.
I got:
- serious extra go beyond 4000rpm.
- always looking for 7th while cruising at 70-75 mph.
- better fuel consumption: from 140 miles per 16 litres to 180 miles now. (2 litres left in the tank at refill).
- if I thrash up the twisty roads on a 2000ft range near here I'll drop back to abt 140 miles/tank.
- rid of all fueling and surging complaints.
Have a look at my how-to post in Boxer Performance.
Seating position:
-I'm 6'4'' tall. I have the sports bars above the upper triple clamp.
- my major problem was preventing myself sliding forward onto the tank under hard braking, especially on steep down hills. (BMW seem to have a thing about geting you on the tank on all their bikes. R1200GS - arrrggghhh!).
- so: I've remove a lot of the foam in the rear half of the seat and raised the front by putting an 18mm rubber block under the front edge to reduce the forward slope in the seat.
This is reasonably effective but will have to suffice until I get around to making my own carbon fibre seat base.
It's quite comfortable for 200 mi start/stop rides, but my new base will have a that bit more finesse to allow 600 mi+ touring days.
