seating

I find myself putting my feet on the rear pegs on the highway and I have even considered clip ons for the bars. I miss the fit of the CBR I used to have as I find it very hard to keep my back straight on the Vmax, it always wants to curl and I want my knees bent more and my feet further back...

I am re-installing my carbs and I guess I didn't pay close enough attention when I took them off. When I am seating the carbs, how far do they need to be inserted in the intake boots to be fully seated? When I look under the carbs there appears to be a gap between the main carb body and the top...

I am thinking of adding an Aprilia Tuano to the stable. Anyone out there who has one or ridden one lately that can tell me if the seating is as upright as the vmax? I am having a hard time finding one locally to sit on and check out. I have a bad back so seating position is important to me...
