De-restriction trouble

[Will]

Hi,

My dad and I are currently trying to de-restrict my NSR. But we can't get the bolt out that holds the fuel tank in place out. It seems to be stuck in by the fairing. Can anyone tell me how to remove it?

Thanks

Will

Get an adjustable spanner and secure it in place (so the bolt won't move) on one side, then use an 8mm (maybe 10mm) socket to loosen the bolt. You can do it without removing the rear fairings, the rear fairings pop off slightly because they're held in place partly by a plastic stub with a rubber washer thing.

Right, new problem. We now can't get the left screw, that holds the air box in place, out. We've been trying for about half an hour and we can't shift it. We're going for the big one like it said in the instructions. Can anyone help us on this?

Thanks

Will

That was me. Forgot to log in.

Bloody hell, it ain't that difficult, you ain't turning it with enough force. Try getting a spanner on it then using a screwdriver or something for extra leverage.

Ok a quick update:

We've successfully removed the intake restrictor. But when I turn the ignition key to 'on' usually their is a whirring. But now when I turn it, it starts to whir then just stops. Have I not replaced something or put something in the wrong place? Also I was told by 'TrueBlue' that it took him about 2 hours to drill the holes. Well we've been going on and off for most of the day and we've only managed 2 nearly 3 holes. We're using a 500 W drill. Can anyone tell me if this is enough or are my blobs of weld stubborn.

Cheers

Will

That was 2 hours for the whole thing mate

Make sure you have decent i.e sharp drill bit. And drill small pilot holes first. I used a 2mm drill bit then 5mm then 8mm then 10mm.
A 500w drill should deal with it no probs, I used a battery drill

Is it anything to do with the powerbands? My mates DT125 does that when you switch the ignition to "ON". Same with the Cagiva Supercity125. I wondered what it was to begin with. I could be wrong but that's what I've been told.

On my RGV the whirring noise when you turn the ignition on was the powervalves opening and closing.

Bloody hell

And I'm pretty sure the whirring is nothing to do with the powerband or powervalves. Anyone who has a fairly recent NSR, look underneath the tank and you should see a shiny silver circular thing. With, what looks like, two pieces of wire wrapped around it. This is what I am referring to.

This is the servo for the powervalve*, check to see there's nothing blocking it.

For the exhaust, ideally you want a faster drill, but more important is decent drills in small sizes. You will need a few 2 or 3mm ones, because tehy will blunten and brake.
Crappy drills often become blunt before you've finished the first hole. You need small ones to make accurate holes, then a bigger one to drill it out.





at the powerbands... talk to bend that does a good line in replacement ones

And what about my Go faster Square Can.
Or my loose chain.

Or my lack of starter motor (less weight you know)
Not to mention the go faster scratch's and squidgy grips...

I have finally de-restricted my NSR. One problem: It only goes 60mph. Can anyone tell me why it's going so slowly?

Cheers

Maybe you forgot to change out of 3rd gear!

Or you've put on about 300lbs in the past two days and your bike just can't take it anymore.

Hi

Given that you say it no longer whirs at you when you turn the ignition on I suspect you have disconnected the power valve

All the best

No it does whir when I turn the ignition on now but the bike only goes up to 60mph. Any ideas?

[Scooby]

You've probably put the powervalve in the wrong way.

Sorry Scoob this is going to piss you off but could you elaborate on what you said as I'm not mechanically minded.

And sorry for having a go at you the other day. I don't know why I did that I'm not usually like that.

[cc]

have you drilled out the restricter in the exhaust or have you pit a new exhaust on

[Will]

We have drilled out the restrictor.

[Scooby]

Ok, apology accepted

When you took the airbox and stuff off to get to the carb did you interfere with the powervalve in any way? I did this but I only took the powervalve off when I dropped the engine out, and when I put everything back together I didn't assemble the powervalve correctly. I put something in the wrong way and the powervalve wasn't opening properly.

I am suggesting this because when people say my bike's restricted, and it's a 2 stroke, a lot of people may think it's a powervalve restriction, so if anyone at all has fiddled with it (even before you had it) it might be that.

Well, unbelievably, I've come across yet another problem with de-restricting my NSR. I've just been told by Bernards in Peterborough that the 2003 model can't be de-restricted. Is this true? Has anyone on this forum de-restricted their 2003 NSR?

Any help would be very welcome.

Cheers

Will
