Posted: **Thu Nov 23, 2006 10:38 pm**

is the uk speedo the same? i need more than 112 mph i'm in rathfriland mcc and they all 600cc and over, the 250 was hard work keepin up, if i had more speed i'd be able to keep up easier an enjoy my sunday away from the other half better. if its the same i'll "modify" it and try it then let you know what it does. thank f**k 95%of the traffic branch over here have bikes, pity about the state of the roads

as far as i'm aware this is an import speedo and needs to be tested to see if our theory works?

can you tell me if a denso cdi will fit my import i assume thats the make on the rest of yours and theres numbers on it ...
21119-1332 and 131800-5610 can anyone help???

jap clocks u can fit rev booster onto, goes into back of tacho, uk clocks u need to change the cdi unit. U can swap clocks from one bike to another but if u want full power u wud need either rev booster (kmph) or sp cdi box (mph).
dunno about the carb restriction kits etc never had a bike with them in.
Hope this helps a bit.

Hi All

New to this forum - I am a Mechanical Engineer working as a Project Manager for Bentley Motors in Crewe - hello to all in the North West!

I bought a L3 "Itoham" Limited Edition ZXR400 (presumably an import) for my son recently, and we are busy restoring it. It has km/h speedos, no sign of a "black box", a Denso (Japan) CDI (P/N 131800-5920) and carb restrictors fitted. I have read all the posts that seem relevant, but still have some queries...............

Regarding the speedo / black box / CDI restrictors

1. How do you know which is a UK (unrestricted) CDI ? (part no / model ??) What denotes a Japan CDI?
2. Are there 2 "electronic" restrictions or one ? i.e there is the speed limit one, disabled by the speedo mod (as per the FAQ's) or the "black box" (which I assume is a workaround sending the CDI a constant signal and is equivalent to breaking off the tab inside the speedo). However, there seems to be some posts indicating a rpm limiter in the Japanese CDI limiting revs to 10k - is this true?
3. Where does one get a "black box" from ?
4. Where can one get a known UK CDI (E-Bay sales seem to be from bike breakers who do not seem to know which CDI is which....)

Cheers
