Simple question, can you ECU restrict a curvy? Know next to nothing about SVs.. do curvys even have an ECU?
Cheers!
No. It's got a carburetor rather than fuel injection so doesn't have an ecu. I think.....

No. The ECU just controls spark and can't be restricted.
On the curvy you use washers or restricted carb sliders

Cheers all, that's what I thought. As a novice, how easy would it be to install washers myself?
Done basic things before such as spark plugs/ignition coils/oil changes etc on a car, but that's about the extent of my 'mechanical' knowledge :D

1: Side infill black vent things
2: bolts to seat out
3: seat off
4:2 bolts at front holding tank down undo them
5: undo tank near battery . Unplug connections to tank
6: remove airbox
7: undo bolt to loosen carbs . 1 is hard to find . Lift carbs .
8: place washers in slots. And carbs back on :)
And go back to putting it together . Make sure you put airbox on right . And put the hose in the bottom of tank . I missed mine and got about 40 miles to a tenner lmao . Plugged it in and all was well .
Any one would like to update this then feel free . Just a quick guide

If you get the certificate you'll have to get a garage to fit . Unless you fill it out and stamp it

That first ebay link is to a pair of Suzuki's own restrictor carb slides, which are fitted into the carbs themselves rather than the washers which are fitted between the carbs and the inlet rubber.
They both do essentially the same thing - restrict the intake to about a third or thereabouts of it's full opening - but they do it in quite different ways. Neither are difficult to fit, but If you're not fully aware of how it should be done, then the 'washers' approach is the easier and less involves slightly dismantling of the two, also bear in mind that if you use the slides, while the diaphragms couldn't be described as fragile but can be damaged by improper fitting, as those ones are second hand there are some difficulty in fitting them as the diaphragms can dry out and shrink when not in use. There is an easy fix for this - but I know of two sets that have been damaged by trying to fit them whilst shrunken.

True, but they can ask for it.
