De-restricting an NC30

[kingnathski88]

My NC30 is currently restricted to 33bhp, of which I have no intention of removing untill I am 19. I know that you can do something with the clocks to make it go faster, I have had 110 out of the bike already, but if possible I would like a little more.

If anyone could offer me a little insight I would be very grateful

Japanese import NC30s have a restrictor to 180kph (118mph) in the actual speedo unit itself. There is a small opto-electronic sensor, the beam of which gets broken by the metal plate attached to the speedo dial weight.

To remove this, you need to remove the clocks, take off the back of the speedo and drop the unit right out. The plate is obvious, it is attached to the silver round bit on the back of the speedo needle. Remove the plate carefully (!) and reassemble, job done.

Now go and find a (private) big hill cos you'll need it to get a 33bhp NC30 over 118mph

Cheers

Grim

Surely that can't actually restrict how fast the bike can go, just restrict how high the clocks can read?

[the grim reaper]

Errr, TZR, read my post, there is a SPEED limiter built into the CLOCKS on Japanese import NC30s. I know, I had one, I removed said limiter and it then made it to about 135mph (on a private road, obviously).

Cheers

Ah bollocks, I didn't see grim's post before I submitted mine, once I'd read grim's I attempted to swiftly edit it into some kind of question, but was quoted beofre I could manage it

[DynaMight]

No point yet if it's going to stay restricted, I never got mine after 110MPH restricted. Funnily enough my jap restriction used to kick in at 125MPH, I assume someone tried to remove it but didnt do it properly, the M-Max box sorted that out though.

So, do you mean it wont make any difference to my speed?

Sorry if I sound dumb.

[edd]

What they mean is you are restricted to 33bhp, 33bhp bikes cannot reach 118 mph, thus having a restriction at 118mph is irrelevant to you. Since you cannot travel over 118 mph you wont be able to tell whether has been de-restricted or not, this is irrelevant because your 33bhp restricts you below this speed anyway, I hope this clears the situation up a little.

Also, due to the fact you are already looking for more performance I dont think you will serve your full restriction period, not many people do.

You would go faster if you weren't restricted. As stated above.

Although if you do want to remove the japanese speed restriction all you need is a motrax converter as then the speed restriction will kick in at 180mph not 180kmh and your NC30 is never going to do that.

Nah, don't bother, removing the plate that cuts the optoelectronic beam is free and takes all of an hour or two to do. There's a method on the net somewhere, I printed it out to do mine bu that was about 7 years ago

Cheers

a 2 stroke mito 125:

A). Has less than 33bhp
B). cannot do 118mph

the clocks might indicate that fast, but they are wrong. The manual might claim 33bhp but they really produce around 27-28 ish

Cheers for all your help and advice, yeah, you may call and think all sorts of me, but I was considering taking the restrictor kit out.

[Marci]

A STOCK 2t Mito125 can't... a tuned-to-33bhp Mito can...

Fastest I've ever seen a *full power* Mito do was a teeny bit more than 110 mph (indicated) which dropped to 90 when it hit a gentle incline, and it never reached the ton again on that test run The guy swore blind he was doing 120

I don't doubt it and I'm not disputing it... just my particular mito has had rather more work than others... being an ex-raced trackbike prior to conversion to roadbike. Mine won't hold it's speed on an incline either sadly, but it can get there quite happily, repeatedly when not on an incline...

Cheers, any chance you guys know how much they cost and where to purchase them from?

[Wafer_Thin_Ham]

30 quid from
https://www.motrax.co.uk/Index_pages/accessories/kilo_mech.htm

shop around on look on Fleabay. Note this will also change your odo to miles as well, so best get it converted to Miles with a mileage correction company, or look on the internet for ways to wind it back. Unless you don't care. (I don't know if my odo was converted when the mph converter was fitted)

You still wont be able to go any faster for the reasons we all explained earlier.

getting a converter is useful anyway IMO.

Just take the restrictors out Might not be legal (and may invalidate your insurance), but as long as you are a good boy and dont go speeding everywhere noone will know
