Right I did the R6 throttle tube mod on my road SVS, although a step in the right direction, I thought it was far from a revelation, one still has quite a ‘twist’ to get to full throttle.
When I got the R6 tube, I put that and the stock one face to face to assess the difference in diameter of the cam part i.e. the bit that determines twist to pull distance ratio … and to be fair it seemed very little.
For my track SV that I am currently building, I have decided to take matters into my own hands and have ‘modified’ the standard SV tube that came off my other bike when I put the R6 tube on.
I have to admit I have been less than scientific with the amount I have expanded the cam by (you are looking at the black plastic bits I have epoxy’d on to increase the diameter/circumference). I’ll get round to fitting it sometime, but my hope will be that it will make the throttle truly ‘quick action’. You may notice I have slightly ‘ramped’ the end of the twist more than the start? so that I maintain more low down 'feel' :)
I intend to fit, try, then file to my own specification, so I will have a custom built quick action throttle 8)

Anyone else tried this?
