What have I done?

Hiya all,

I have a bit of a project on the go...
http://www.antidusty.co.uk/gallery/index.htm

I am currently trying to tie down what is causing the bike to cut out
(briefly and intermittently) and as a result am posting here as a last
resort before I go for a complete rewire over the winter...

I have a GPz1100 B2 which has had what Im told are ZX7 Front and rear ends
added. (Please comment if you know better...)

I can only narrow this down to either wiring being old and mouldy or the ECU
on its way out...

I am not in a position to be able to pay a mechanic to stand round for hours
looking at her just to tell me (300 quid later) that he thinks its
electrical, and would welcome any advice at all

Are there any support groups out there which specialise in the old GPz1100
B2?
Can my hybrid still be called a GPz? ;-)

I can be mailed using the link at the bottom of my web-page.

Thanks in advance for any help or suggestions

Dusty

 

Remove the sidestand cut out switch if its still fitted, check the kill
switch is in the correct number of pieces.

Talk to a Kawasaki main dealer about getting the FI control unit and the
ignitor checked. Won't cost much to get them checked. Much much cheaper
than rewiring only to find one or the other is iffy.

If they check out, then play 'hunt the fractured cable' and 'hunt the
corroded connector deep in the bowels of the bike'

 

Oh, I forgot to mention,

1. I want to keep the fuel injection
2. I have removed the sidestand cutout and bypassed it

Thanks for the advice so far

Dusty

 

X-posted to ukrm - Champ knows more about these old Kawasaki FI
systems than most people.

 

Coo, the deja-vu is strong in this one ;-)

 

You idiot - it was already here

Yebbut, still not that much. There's no magic - you just have to
check (and re-check) everything.

Oh well :'-(

Worth a try... will just have to wait and see what suggestions kawasaki get
back to me with...

but I have a couple of questions!

I noticed on the wiring diagram for the FI that all 4 injectors are linked
to the same wire exiting the ECU, (now I havent double checked this on the
bike yet, but I will) Surely firing 4 injectors simultaneously is just
wasteful? or lazy? or a very rough wiring diagram... Anyway...

Does anyone know of a source of ECUs and Injectors for me baby (GPz1100b2)
and if so any idea what prices I would expect to pay ?

 

No, it's true - all the injectors fire together. Even at low rpm (say
1200 - nice easy number...), the engine is going thru its induction
phase 20 times a second - the atomisation of the fuel is more a
continuous activity, varying by quanity, rather than a set of discrete
events.

Tough one. Many of them failed over the years due to weather ingress
and the like. There are a few specialised Kawasaki breakers, but you
may struggle :-(

 

Bugger...

Just found a guy who does ECU diagnosis but dont know anything about him,
based in upton on the wirral...

Gonna run the bike over there tomorrow and see what happens there!

Thanks for your advice fellas, its all needed!
