Speed restrictor

I've read a few post about jap bikes being restricted.

As I only got the bike on Monday and ever since then there has been 6" of snow on the road, I haven't been able to see how the VFR performs. Are all the imports restricted and how else apart from riding it would I be able to tell if it is restricted?

Banoffee,

Its an 89 G plate VFR 400 NC30.
Also it has wavey Galfer discs ( Galfer speed kit) with F/R braided hoses, do these offer a great advantage over stock?

Cheers

discs are cosmetic, so not really.

hoses offer a little better performance, quality ones dont expand under pressure, so you get the full effect on the calipers.

restrictions are only on the speedo, if you whack a kph - mph converter in then chances are youll never get going fast enough for the CDI to be limited or you can add a resistor to the orange and blue cable that goes from the clocks to the CDI in the rear of the subframe to ignition live, i think its a 2.4 or 2.2 ohm resistor, i cant remember. ill check tomorrow when im in the garage.

also you can buy an additional deristriction unit from Rick oliver a plug and play for under £50 or a honda HRC one for around £200.

Thanks for the reply,

It already has a MPH clock fitted.

What should it be resticted to - 110mph? if its still there.

Go flat out (on a private road of course) and see how fast it goes. I rarely go over 112 on mine anyway as not many private roads round here that are long enough :grin:

Resistor from RO cheap and very easy to fit. However if you're feeling flush you could always get an Ignitech CDI :whistle:

112mph (180k)

You say it has a mph clock.. is this a UK clock or a mph face from one of the after market suppliers like redial?

Either way.. if the clocks been messed with i'd say the speedo restriction was probably taken out.
