Thanks Sulli, may be interested. I just broke the glass and the needle. Hope the rest is okay.

By the way, your link didn't work....

My tacho is a bit different to that one Sulli.
It is the one that doubles up as the voltmeter as well when you push the button. Will post a pic when I can find my phone cord....

But thanks anyway.

Can you get replacement glass for these?

Isn't he on Evans Rd, Salisbury?
I used to work down on the corner at Alstom years ago....and the old Commonwealth Engineering.

Will check it out. Thanks.

Well I found a dashboard combo in good condition, so bought that and put the old one aside for another time.
Started welding up the cracked plastic casings, will post pics as I get time.
Got a mate who has a Z1R MkII who wants me to fix his side cover, so another little job waiting in the wings...

Been hard getting stuff done lately, moved up to the Blue Mountains recently and work is keeping me too busy.

Another question:

I cleaned up the fuel tank a little and found a crack in it on the top fold line about 2 inches long.
There seems little else wrong with the tank, so would like to get it re-welded. I am a welder myself, however I am a little concerned about the risks of doing it myself.'
Anyone know of a pro repairer around Sydney that has a good name?
I saw an ad for a guy in Nundah QLD, but the logistics of transporting a used fuel tank seem to be a little daunting/expensive.

On a side note, the other weekend (on a Sunday) heading outbound, I saw a GPZ 900 on the back of a Ford ute passing through Blackheath past the Fish & Chip shop. Anyone we know?

Have you tried findapart for another tank? Maybe a cheaper option.

Hopefully the 900 isn't off to a breakers. It surprises me how few 900's you see. I have one but I don't think I've seen another in Brisbane, well on the road at least.

Thanks pkay. will check it out. There was one on Ebay for $105 plus about $45 in post in the Gold Coast, but it was pretty rusty. Not too keen on that one.

Measured the crack, it's actually 100mm long.

That 900 looked too pristine to be going to the wrecker. My guess is it was being transported to an event. Or returning from one? Keeping the k's down on it I guess.

Hi, I’m new here and from the UK. I’ve a couple of GPz750s for restoration. One’s now back on the road for the first time in seven years and is my current focus.
Image

It’s an A1 so it’s going to have A1 decals but in these colours.

Image

I’m not doing the frame green though or the wheels white; standard black frame for me but blue wheels so similar colours to this Z750.

Image

I also like the idea of anthracite with black and silver decals for my A3 (similar colour scheme to the later gpz900s).

They’re great bikes and I look forward to seeing how yours turns out.

Very nice, I am going to do a KR250 in that green colour next year.

I like the GPz750 in the black. I must get mine out of the back of the shed and fix the leaking carbie and do the float heights to improve the cold starting.

Looking good there David, nice work. Welcome to the forum too bye the way.

Actually pkay, black is an interesting idea. Might think about that, I could do it myself then.

Mate has a Z1R Mk II. Carbies on that leaked too. His mechanic said it was the side stand letting the bike lean over too far causing that.

Couple of weeks ago, the pivot bolt on it fell off and the bike fell down. It had been broken a while just stuck in there bending the inside tab on the stand until it fell out.

But anyway, the bike leaning over too far on the stand allowed the fuel to dribble out and opened up the float valve. The petcock isn't vacuum operated and he had to turn it off when parked.

Simple cause, never figured why until the mechanic told him.

Thanks @The_fixer. Only the top bike is mine, the other two are just to show where mine is going.
I’ve actually got three GPz750s, the third came with the second but in pieces along with many other spares. I’m intending to build a special with that one and recently picked up a ZR7 for bits. It’s got a 160 section rear tyre and the gearbox output shaft has been lengthened to accommodate it (standard Kawasaki) so I’m thinking of using the ZR7 engine, front end, rear end, loom and probably other bits on the GPz frame.
It’s a project so won’t be completed anytime soon but meanwhile I’ll get on with improving the one I can ride whilst summer is here in the UK.

Cool David, lots of luck with it.

I have news. Checked out that crack in the tank. Turns out is was a crack, but it was in the body filler under the paint.

Disaster averted. Lucky I probed it with a tool before buying another one.

Cheers. I had a bit of time today so balanced the carbs; it feels a whole lot smoother now. Unfortunately my thirty year old mercury vacuum gauges are a bit worse for wear so I had to adjust them in pairs. It took a bit longer but I got there in the end.

Then took it out and did a plug chop (don’t you just love old bikes?); it’s running a bit lean so I need to get some larger main jets. I finished off prepping a front mudguard for painting. All in all, a good day in the garage.

Good news about the tank; one of mine has a “filler” crack. Should be an easy fix

Speaking of syncing the carbs, have been thinking about buying one of those Digisync manometers.
http://thedigisync.com/
Not a plug for it, but it does seem to be a reasonably priced option compared to the old vacuum gauge/mercury things, with the claim of being more accurate.

I would wonder what level of accuracy would be necessary, but has anyone heard anyone's opinions/reviews of them? Seems to be a simpler setup and read system with an auto calibrate mode.
