hiya everyone, i have found out my FZR is a japanese market bike so it is is restricted it has the kph to mph converter on so that part is done and the ignition wont cut at 180kph. i have learnt that the cdi is also an issue so will need an FZR1000 genesis unit but dont know which one yet. the carbs will need re jetting and a restrictor taking out of the airbox. does anyone have any info on this at all .

I don't know but suspect a set of FZ carbs would fit or at least their jets if you can't get/haven't got spare carbs. The restriction in the air box might be obvious if you can look at a normal, non restricted air box from oooooohh say an FZ 750? ;D

the usual method of restricting an airbox was to have webs blocking the air flow which can be sliced out or , if pressurised (ram air), to have a hole in it to release pressure.

Good link crusty. This is probably the most useful bit from it for you Allie.
1. The most important is to change the 2LM ignitor box with eighter a 1FM (UK) or a 2NK (US), both FZR1000 and are "plug and play". Look for it at e-bay. 2. Pick out the air restrictor in the air filter box. This is a rubber fixed with a steel clamp sitting in the middle of the inlet to the air filter box. Throw the shit away, as you hopefully never need it again. 3. Due to the increased air flow you'll now need to re-jet your carbs. I'll guess your carbs are BDS34, and you will need: - Main jets: two nos. #107,5 (outer carbs) and two nos. #105 (center carbs). - Gasket (o-ring) main jets: four nos. - Pilot air jets: four nos. #125.

You've done a lot of work to it Allison. Well worth 800 if you ask me.

my engine number begins with 1fm !would that make it a uk bike ? and i should be looking for a 1fm igniter box. i think i will take it apart tomorrow and find out if it has been de restricted alrerady yes graham i know i do like it ,iy is different but still very quick it needs the frame painting and it has some cracks in the body work if i kept it i wouldnt stop , and it would never be on the road i only did 900 miles on it last year !!whereas before i did stuff to it i was doing 5000 ! on it , i want it to be to clean and tidy , i dont think i will have that issue with the FZR so wont mind getting it dirty so will ride it more. i found i was looking after the fz to much ... if that make sense

just tried my FZ igniter box on the FZR and it works fine ! took the 2lm one off and put the 2mg one on, I had heard that someone was running a 2mg box on there early fzr1000 and it had been fine, So should i get an fz cdi then ? confused its all getting a bit to much for my little brain

another question, when people put 1000cc top ends on fz's do they still use the FZ cdi ? becuase if that is so and the 2mg cdi works on the fzr then i coudl use an fz cdi to de restrict. as people say use a fzr1000 cdi on the fzr 750, does that all make sense .. well it does in my head

I don't really know enough about TDIs to know.
The only way a TDI can limit engine power is by limiting engine speed. There's only a few ways ways of doing this. Either cutting engine revs when a given preset rpm is reached (difficult in a simple transistor circuit), having the ignition retarded slightly at all times (pointless and you loose power all down the range rather than just at the top end) and having a weaker spark (this will only affect the top end as the fuel doesn't get burned quickly enough to continue to speed up the engine.
I reckon weaker spark is the most likely. Find out what a derestriced FZR will rev to and see what yours does.
Edit: Just did some checking and the FZ750 has a rev limit of 11.8, same as the unrestriced FZR. The 2MG one should be fine but the thou *may* be better. It is restriced by using retard...

Allie
if I were you, I wouldn't trust that I'm right about this, but if you are happy with the power that you are getting from the 2 MG one...

went for a long ride today with my new pipe on the FZR, totally different ride to the FZ, not as buzzy or rev happy, although the fairing is alot better and the riding position for me any way as i am a bit long. This was a check out ride, i still have the fzr cdi on it and you can tell it is held back , the engine is good and has a very raw feel compared to the Fz but it has alot of potential, at the present it need the back brake sorting as it is very poor it also has a weave when going in a straight line might be bearings it feels that way , or it coudl be the very very scrubbed race tyre on the back. will up jet when i find what type of jets it uses, i think mikuni slots. oh has any one got a spare 2MG cdi they want to get rid of.? annnnd the guy who was going to buy the FZ has not been in contact if he has not called by sunday it will be back for sale, or i coudl take all the exup bits off it and put them on the FZR... nah not a good idea
