NSR125 power valve delete

[2tenjoyer]

Hello.

I’m looking to remove the computerized power valve system in my NSR 125 and thought of an idea to replace it with a manual gas cable. Do you think it would be possible to do this kind of thing and would it work just as well as the computers brain?

The power valve on 2ts opens based on revs. That's why its controlled by electronics. Why would you want to control it manually?

keep the bike in restricted form. the engine will last a hell of a lot longer.
although they are a lot more fun on full power.

The whole point of a full power NSR125 is it's reasonably tractable at low revs and then goes mental at the top end.

Let it do what it does.

When the power valve controller ripped up its plastic cogs on my exup (admittedly not the same setup) it when from a 180mph missile that could pull in top gear from 30 to an 80 mph chugger at max throttle.

That'll be down to you not jetting it accordingly because the UK version had different jets to the full power version.

Do you have the powervalve and controller?[/quote]

I’ve only got the power valve computer, need to replace the power valve and the servomotor

[Nobby the Bastard]

How do you propose actuating the powervalve if you don't even have the powervalve?

If you have the CDI and a working power valve, why are you trying to control it manually?
