derestrictor ???
hello peeps
right a think av got a problem, well a know a have a problem but bare with me as am not the most techinically minded
in the quest for more speed, ive been thinking my bike is restricted, as it wont get over 110, av tried another cdi box that a bought and that caused it too over rev and cut out when coming to a stop
so i put the old cdi back in and it was back too plain sailing, just not at the top speed!!!
thing is that ot me confused is that it revs right up too 14 000 revs with my normal cdi in, but doesnt go ove4r 110
so a phoned the lad who had the bike before me, and he said it was the little red box behind my speedo that was doing this, so he says take it out and a will notice the difference. so a took it out and it only goes to 12000 rpms now, then hits a flat spot ???
ill take a pic of this lil red box, so you can all have a look but it has got my head in bits totally, i also asked him if i would need the carbs seetin up again and he said no a wouldnt
so can anyone shed some light on this for me please ?????

It’s a restrictor in the Speedo. When you hit a certain speed, it wont go any faster. I thought it was closer to 115mph (but your Speedo is prob kph right?).
Now what I’ve done is simple, I got a kph to mph converter and fitted it to the speedo. Now, when I hit 140kph (its mph really, so you can remove the silly speedo overlay sticker) and I don’t go near the limiter any more.

right guys ive taken my old l model speedo that is on kph
followed the article on removing the rev limiter to a t, nd sat here looking at it now and it has no metal clip that provides thst enables the restriction
so a imagine this will be the same on my mph speedo
so any ideas on what it might be then, am sure the speed is restricted on the l models by the cdi and not the speedo, as ive cracked my old kph open and there is no clip there

ok so you've ruled out the speedo, could possibly be in the cdi or carbs, as far as i am aware there's only 3 types of restrictor on the zxr400.

hmmm am not sure which one it is am not the most technically minded ya see
a bought a uk cdi before and plugged it in, but it caused me loads of problems when fitted, like when comin to a junction it would stall and cut out, takes ages to get running again as well, so i put my old one back on
could be that the cdi a bought of ebay could be faulty ???
a was told its should be plug and play straight away , is this right ?
or do the carbs need settin up again ?
or like you have mentioned, could be washers in the carbs , but like a said am lost with it
its a 94 l model, that has been imported , its green and white with purple and pink decals and has the ninja logo on the tale end

cant be the speedo mate , i took the imported one off and replaced it with a uk one, also took the import one to bits and there was no restrictor there like in the article, cant imagine the uk one having one in there , am starting to think its my cdiGemini wrote:if its imported then its most likely restricted thru the speedo
