Restricting a K6 by valve adjustment, and that's cheaper than fitting a restricted ECU? Are they having a giggle?

As I'm sure you're fully aware, the valves on the SV aren't the easiest things to get at - quite a high cost in labour. I've been quoted £200 to even look at my valves for clearence checks as per the schedule!! That's without changing them!

Whereas the ECU, is a matter of undoing 2 bolts (riders seat), lifting the ECU out, unplug it, and plug the restricted one in! The only reason you need a shop to do that is so you get a certificate saying it's been done.

Restricted ECU's pop up from time to time in the For Sale section or eBay (I've looked & can't see any on eBay at the moment).

As for the restriction being jerky, I assume you're taking that to be the restricted ECU being jerky? Not at all. Power delivery is almost identical (or so I'm told) to a full power bike up until around 80-90mph. Then you're risking getting pulled over anyway.

If it is jerky (regardless of the restriction method), there's plenty of threads on here about how to sort it out. Basically a throttle body balance & TPS adjustment.

£300 for swapping the ECU seems a tad expensive to me - but then I'm not sure how much the part is direct from Suzuki.
