Obvious question: What bike?

[anonymous-user]

Removing the ECU will mean the engine doesn't run, as it's controlling the fuel and ignition for the engine.

I did a very quick google search and found this: https://forums.sv650.org/showthread.php?t=220721

Probably an official way to do it from Suzuki (likely remap) or aftermarket way (Woolwich racing remap etc).

Following Euro 4 manufacturers had to include double redundancy in the A2 restriction, for example on triumphs they include a restricted TPS sensor and a restricted ECU, if only one is replaced or removed the bike will still be restricted. Best recommendation is to take it to Suzuki and have it removed properly.

I bought a new SV back in 08/09 at the time I was restricted, about a month or 2 after i no longer was so they swapped over the ecu and gave me the old restricted one back.
It's just a black box which plugs in, can't imagine it's hard to replace yourself

My mate’s son has got a Versys 650 which is restricted.

He’s under the assumption that it’s only the throttle stop that is restricting it and it takes 2 minutes to take that off.

It was restricted second hand. I wonder if the shop just did the easy way and just fitted the throttle stop and gave him a certificate anyway.

I must ask him next time I see him if he knows whether it’s been done properly or not.

I've got a 07 ER6-N which I've had from new, and yes that literally had a screw in stop on the throttle cable that stopped it going more than 1/2 way round.

When my restriction was off, I called the dealer to ask them to remove the restriction and they told me to just undo and remove the screw.

Electronics eh?

Back in '89 I bought an NSR 125 and the restriction was a penny washer welded into the down pipe and a lump of plastic stopping the carb slide from going all the way up

Things were a lot simpler then.

A throttle stop is as 'proprer' as any other way, assuming its a 'kit' from a company that's verified the throttle position is correctly limited to ensure correct power output - given he had a certificate this seems likely.

Much like the 33bhp days when everyone had sports bikes with a piece of paper stating they were 'restricted' ...

The double redundancy mentioned above is for manufacturers to follow, no need for that if being fitted on a pre euro 4 bike or a euro 4 bike that's not factory restricted!
