There are a number of ways to over come the 10K limit.

In you case the quick and easy way is to refit your speedo.................but leave the drive cable in the spares box.


You should have full 14K rev

The blue CDI you bought was prob a L model one I'd guess it wont work unless you also fit a L model rotor................but there may be other reason as to why it wont work

The M CDI doesnt work for H models. You could try a speed converter and use kph clocks.

Other option as you rightly said is the resistor mod.

Dont think you have much else choice other than replacing the entire loom for an L model one so the CDI works.

what you will find though, is that it wont rev out over 10k when you hit 180kph (110mph). Hence, you use the kph-mph speed converter and use the speedo in mph, since the clock wont get to 180mph youll never hit the limiter. This does of course, mess your mileage up

Being a race bike I am guessing he doesn't care about milage, as long as he has removed the circuit board from the clocks and has the speed restrictor plugged in the bike will be full power - it will never trip the 180KPH sensor so its good to go all the way to the rev limiter well within the Red line just like mine :smt003

On a road bike and as long as you don't care about knowing what speed your doing then Cargos tip about removing the speedo worm drive will work too :smt004

MM!

once again guys a big thankyou,
i have took out the cicuit board and fitted it into a small plastic box for protection and yes your right its my track bike so no speedo or milage clocks fitted luckily had the original kph clock in garage
cant wait to get it on track to see what difference it makes.
cheers guys
