I give up on them

[andym]

Decided to fit the new (good usable condition it said) thermostat housing to the gpz today... topped up the water pressed a hose and it pissed out of the new housing too

THEN decided to try getting the zxr started, after flattening the batteries again, I thought I'd check the compression (up to about 35 then dropped to 25 when I turned the engine over again), so I checked the timing, turns out the inlet was about 2 teeth off the right setting, so had a bitch of a time doing that, when I tried to put the CCT back in the chain was too tight to even get it near the engine for some strange reason (looked down into the engine and can't see any problems with it).

Got the timing set properly, charged up the car battery and bike battery.... and hardly even a fart from the engine before they went flat again, so I tried to bump start it and ended up having to push the bastard back up the hill again... checked for fuel, checked for spark, swapped coils, swapped leads, swore at it a lot... still nothing. Eventually I asked the neighbour if I could hook up the jump leads, and even with that it sounded like the battery was going flat.

So now I'm seriously considering just scrapping the pair

Weren't some of the local pikeys wanting to buy them?

I had an old kawasaki which I kept putting new batteries in and it still sounded flat, turned out to be the the starter magnets had fallen off so always sounded lazy. try powering the starter direct from a good battery and see how it sounds.

Do you have a working car? Just jump from that.

OK I think I might have figured out what the problem is with the zxr...

Should have been the first thing on the list, but finally got round to testing the compression:

cylinder
1 - 45 psi
2 - 0
3 - 0
4 - 85 psi

So I checked the valve clearances (again I should have done that when the engine was indoors), I found all but 1 of the valves were open on the inlet side. So now I need to find somewhere to get 2.25 shims (wemoto only go down to 2.30 and I can't find anywhere online to get smaller).

I have a shit load of 55 shims, but need the following:

2 x 25
3 x 30
3 x 35
4 x 40 (need 7 but have 3)

I have 3 x 40, 4 x 45, 7 x 50, 16 x 55, 1 x 60 and 1 x 65.

Now a quick silly question... Are the buckets all the same size or can they be as much as .05 mm out? If so how would the size be checked (other than trying different ones then checking clearances).

Paddy I don't have a car... mind you I don't think it would make much difference

if the shims are too big can you not get them ground at a machine shop?
in the past with peugeot car shims I have stuck em on to a big magnet and rubbed them on a sheet of 300grit wet and dry (wet and on a sheet of glass) to get correct clearances.
it does take a while but it is almost free lol

Learning curve, you're getting to learn a lot about an engine and when its done you have a zxr 750 youve rebuilt yourself.

Keep up with this dont let it go.
