I'm after a voltage reg/rec for the new engine as its a different setup.

Posted

just had a look, mines a different number

I've got a spare 12R-A0 SH233

your a bit far though, prob cheaper to get it in the UK.

Well maybe, let me know if you can't find one! They seem to be all over the place though...so you can probably find one close to you.

i went to do a bit more on the FZ today....

....and I just thought sack it. and changed the engine over so the new engine is in so I just need to put new needles in the carbs (£52 EEK!) and fire her up (hopefully)

the new reg/rec arrived from China too, happy days :)

Question;

the original coils I have are 2.43 to 2.97 ohms and suit the original ECU

the '91 xj engines have 1.8 - 2.2 ohms, anyone think it will fry the ECU? ( it took me 6 months to find one)

Measure the resistance of your coils first. If they are high then swap coils,,

Low ohms coils work better and less back pressure /feed on the cap.

I've found a set on ebay with the same primary resistance (fazer ones) but they have a higher secondary, prob due to the higher compression engine.

Posted

Well just thinking about the way a coil works,primary builds and then collapes onto the secondary,in my mind I can't see why the secondary would matter,The voltage has been cut to the coil during that split second and the cap is charging anyway.

So as long as the primary is not resisting the charge from the system then I would think all would be fine.

my thoughts too and at only £15 delivered, its worth a punt.

did some more rewiring today, trying to use as much of the existing stuff as I can, which is quite a lot :)

might have her running next weekend then I have 3 bikes to choose from

Nice.

No photos though :( Picture says a thousand words and words give me a headache. Much like this project I bet.

How come you didn't decide to just rebuild your original engine? Was there any particular reason?

pictures would be boring bits of wire and engine to look at, but if your really keen to see them.

The engine isn't scrap, I have another cyl head to put on and deciding whether to breathe on it a bit.

everything I've done can be undone just as easily.

fitted an R1 reg/rec onto a finned alloy plate I "acquired" in a previous job, should keep it cool and managed to fit the diversion coils in too with a little bit of jiggery pokery.

Awaiting new HT leads and will need to extend the reg/rec wires as the old style had a mini loom on them ;(

Looking good Drew, the motor looks sweet.

yes, it runs great (at the vendors)

awaiting some more wiring products and need to set my floats on the carbs,then it should run again!

Posted

Well I for one dont care what it looks like now,I know you will make it sweet in time.

I want to hear what you think of the extra 10 hp,so heres hoping you get the carbs and elcs sorted soon so you can report back.
