Re: 1973 Zia gasket set and pistons set

Going back to my post above, maybe someone with more experience could come in? Would you expect each cylinder to be showing exactly the same reading (i.e. 70psi across all four) if it were the result of parts wearing or failing? Wouldn't you expect some variation between them, whether it was down t...

Re: Thoughts on new chain and sprockets for '73 Z1

Sprocket change to 530 pitch of course. It is silver because its is a colour that suits the older bikes. Very few when asked wanted a gold chain on classic bikes. My opinion is that it looks better than a drab grey steel colour too ? :cool It isn't a polished finish as far as I am aware, just a sil...

Re: 1973 Zia gasket set and pistons set

Thank you for that. Don't know exactly until the head comes off then i can get them measured up at my local engine building company. The compression test was conducted when the engine was hot,throttle wide open. each cylinder read 70psi. Know for a few years now one day i would need the stem seals ...

Re: Thoughts on new chain and sprockets for '73 Z1

All of the above Weight saving is nearly 1kg per 100 links! Mainly due to thinner plates and smaller pins The important thing to remember is that pre Z1B (Z1 and Z1A) bikes were not fitted with O ring chains. On the Z1B Kawasaki found that the wider outer width of O ring chains caused the chain to ...

Re: Thoughts on new chain and sprockets for '73 Z1

I'm not looking at changing either my chain or sprockets at the moment but grew intrigued by this thread. So, I had a look at what's currently on my bike, it says 630 on my chain and the rear sprocket has 33 stamped on it - can't see the front sprocket but I'm guessing 15? Is this pretty much stand...

Re: 1973 Zia gasket set and pistons set

Your symptom sound like valve guides or just the seals Make sure you do a compression test with a warm engine, fully charged battery and throttle wide open. Or better still do a leak down test. If you compression remains low drop some oli in the bores and retest. If the readings change you do have s...

If you stay with 630 then use JTF521-15 don't forget to space the rear the same amount. I have some lazer cut replicas of the original Z1B/Z900 spacers

Re: Thoughts on new chain and sprockets for '73 Z1

All of the above Weight saving is nearly 1kg per 100 links! Mainly due to thinner plates and smaller pins 530 chains are the same width as 630 but 20% shorter pitch. So the overall chain length increases accordingly. A 92 link 630 chain becomes 110.7 in 530 pitch. I have found 110 to be a bit tight ...
