Quicky question on restriction - advice needed.

Right he said in the shop the restriction they do is a manual one on the valves, I went with that one coz it's cheaper!

He did mention the suzuki one which is £300.
Its a new ECU! So my thoughts are, but i've gotta be quick incase he starts it monday!

Can you buy them second hand? And i presume it can be sold on when finished? If so i need one ASAP

The reason i would prefer this is he said its a lot smoother on delivery which could mean the other restriction deliver being jerky which is the last thing i need when being unstable anyway!!!

thanks peeps

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.

Right ok, I must be wrong on the valve thing, Buts it like a manual restriction rather than the ecu one!

i've looked and i can't find a second ecu anyway, the £300 was just off the top of me head, but the manual restriction was deafinatly cheaper!

If this will be ok then fine, but just head it can be a bit uneven with power delivery!

TBH, I'd pay a little more for the ECU restriction.

I ride a K6, and I can't think of ever hearing any other method to restrict it than to change the ECU (same for all pointies).

If you go the route of a manual restriction (which could just be a throttle stop in effect), then you might end up paying someone (the same shop?) to remove it later on.

If you get the ECU changed, tell them you want to keep the full power one (it's yours after all, not theirs). Then when your probation is up, swap the thing yourself & inform insurance company.

EDIT: Restricted ECU part number is 32920-17G10, if that helps your search. You can get a restricted ECU from anything K3 onwards & it should work perfectly well.

EDIT2: I've had a quick look on the net, and new they're coming back at roughly £220 (plus labour puts you around £300 - but that's expensive labour). I've seen them in the past in the For Sale section for £80 or so.

the other restriction is washer's in the airbox and a throttle stop work's ok but not as good a option as the ecu.

oooo don't know what to do now!

whatever's cheaper check ebay the ecu's occasionally pop up and go for around the£50 mark.

if you purchased the bike from a suzuki dealer the ecu restriction is free of charge according to there website. speak to dangerous dave as he will know about all this

the one i'm having is cheaper! check the net no ecus seem to be avliable at the min!
