Re: Brands Hatch

Lovely bike :up and it has an uncannily similar colour scheme to my original J that I had when I lived in East Kent where I grew up.
What's the spec on yours ?

Re: GPZ11 Injection

Plus, the liners would have been bored at the factory in that original orientation. The early "J" was notorious for oval liners as the factory bored them to size before fitting in the barrel castings. So the original fitting in the barrels did not rely on accurate orientation, initially. ...

Re: Z1000J Pandemic Project

Where did you get the chrome chain guard from ?
I had one of those on my original J back in the 80s but can't seem to source one now.

Re: GPZ11 Injection

If the pistons are matched to the original liners then is it wise to rotate the liner by 90 degrees ? Just thinking that the fit will be different as the piston/liners were bedded in with the original front/back orientation, and now you'd have changed that ? Plus, the liners would have been bored at...

Re: Tacho adjustment

The Boyer system on the Kawa triples fires each plug 3 times every revolution of the crankshaft, meaning that you need a good fully charged battery for it to work properly. Maybe not such an issue on a Z but you've still got 4 plugs firing twice on every revolution.

Re: Tacho adjustment

So it's a triple wasted spark as opposed to the single wasted spark standard system ?? :rock

Re: Mystery starting and running issue.

On Euro versions there should be one vacuum pipe connected to the fuel tap, and the other 3 are blanked off. Yes, leaving them open will allow extra air into the inlets and cause lean running.
I think some of the US versions had the pipes joined up and other bits and pieces for emissions purposes.

Re: Mystery starting and running issue.

It does sound like it could be a fuelling problem. As I'm sure you're aware, CV carbs are notoriously difficult to get running well on pods (even with air corrector kits). I appreciate that may not be much help unless you can source a standard airbox from somewhere (rare these days). This one's chea...

Re: Weak spark on No.2 and No.3

Are those the same coils that can have a tendency to short-out on the frame if not careful ?
(hopefully, others with more knowledge will comment on this)

Re: getting a parts list together

I can confirm from personal experience that some early Js had an oil burning problem.
I used to carry a 1L oil bottle with me when I was doing anything more than 200 miles on a trip !
After a mishap with overheating, I replaced the barrels and pistons with some from a gpz1100b1, and they were fine.

Re: Yes sorry more carb woes....

Still cost you a few quid, but could you pick n mix from these ? You should be able to make one good set, and then sell off the bits you don't need ? https://www.ebay.co.uk/itm/Kawasaki-Z1000J-Z1000-J-Z1100-GPZ1100-Carbs-Carburettors/333388824056?fits=UKM_Make%3AKawasaki&epid=6039009819&hash...

Re: Yes sorry more carb woes....

I don't know whether what I'm about to suggest is possible, but if it's just the carb spacing that's wrong then could you just dismantle the mounting brackets and associated gubbins from both sets of carbs and swop in the Suzuki carbs onto the original brackets? You'd probably need to "make the...
