I didn't realise this thread existed until yesterday.
I picked up my K6 new in July 2007. Right from the start I noticed it was snatchy at low revs but I put it down to the fact that it needed running in, and I'd been off bikes for a few years and maybe lost a bit of throttle hand sensitivity.
But as time passed it got no better and I concluded that the SV is a budget bike with budget fueling that's basically crap.
However, this morning I followed these instructions and made the adjustment. Firstly I found that my little line didn't move until 4500 rpm (I did open the throttle very very slowly - it was definitley at 4500).
I had no problem with the Torx bolts - used a standard tool with a 1/4 open ended spanner. The tool doesn't go very deep into the head so make sure you keep pressure against it while turning it.
Now, bearing in mind that mine was set at 4.5k, the amount that I had to move the TPS was no more than 0.5mm (relative to the original white line painted on it) to drop it to 1500 rpm. I found that tightening the Torx bolts raised it slightly and now mine moves at 1700 rpm, so not ideal but a whole lot better.
So, the test run; As has already been said, it transforms the bike. Straight away it felt smoother, ticked over nicer, and smooth gearchanges are much easier. I don't get that sudden snatchy fuel shut off as I roll the throttle off aproaching junctions any more, and it's vastly smoother when opening the throttle from nothing. Small roundabouts are not a pain anymore!
Many thanks for the guidance.
