High to Low.........
Well after getting my engine going (ZX9R), I had an oil leak from the sump. I dropped the sump off to fit a new gasket, however..........
there is some metal in the bottom, looks to much like some shell bearings, not good news!!!
Now thinking about my options do I......
a) fit and forget and wait for it to go bang (not my preffered choice as I know it's only a matter if time)
b) Get new bearings and the crank potentially re-ground (estimates for this??)
c) Take my chances with another engine, but could land back at the same point.
Any advice apreciated, who's the best to contact to get the crank reground / supply gaskets and I can do the rest.
Cheers
Ian

If you have "bits of shells" in the sump at the least I would have expected oil pressure problems especially when hot ? Do the bits look
blue ?
Take the sump of most new engines and you will find the sump full of swarf from machining etc.......
Can you take a couple of caps off and inspect the bearing ? Dunno if this is possible on your motor.

Hi there
Bit of a mix, some shiny, some more dull, though they don't look blue (but I'll double check).
I can take some of the big end off to inspect, but to look at the mains I need to split the crank case (so I'll have a look at these)
I've only had the engine running in the drive, (no propshaft yet) but had it up to temp and the oil warning light stayed off, but I don't
have an oil pressure gauge)
Cheers
Ian

Do you know the engine and it's history?
If I were you and if you're sure it's bits of shell, I'd buy another ZX9R engine and drop that in. You'd only need a bare
engine and may be able to find one cheap. Then when you have time, strip down the one you suspect damaged and rebuild it if necessary. Then either
sell one of the engines to offset your losses or keep it as a spare.

Ahhhh, didnt realise you haven't run it in anger, its not the norm though for bike engines to spin a bearing, something usually breaks and pops
out the side when they go.
Can you get a second opinion on the bits ? Take em to a local garage, engine machine shop, they will have seen it before......
Oil pressure gauge would help, worn bearings will lose pressure pretty quickly once warm.
You will always have a doubt in your mind if you do nothing.

Bugger,bit of a blow that.
Is the engine noisy at all?
Was there a lot of metal?
To be fair its not uncommon to find bits of metal in the sump bottom, and i wouldn't be too concerned, however if your certain its bits of
bearing, that would be a worry, although i'd expect some other signs if it was that bad.
ZX9's are so cheap now, its hardly worth the hassle and expense of rebuilding it.
If it was mine and showing no obvious signs of distress i'd put it back together with fresh oil and filter, and see what happens. If it does go
pop just drop another in.

I'd cure the leak, put it back together and run it for half an hour to see what happens. Swarf in the sump is why the pick-up has a strainer on
it and with the oil serving the gearbox and clutch as well as the engine there will always be some metal from missed gearchanges etc. Don't
panic and start throwing your money away.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Yes, I did have a bit of a panic............

Especially if its a ZX9R 'C'

I had the shells go on my engine. It didn't burst. Had I stopped sooner then I could have got away with just replacing the shells. I drove on
a bit and the crank was marked. Luckily I had a spare engine that went at the top end.
The rebuild was easy enough and I've done hundreds of miles on it without problems.
If you strip it now you might be lucky. The longer you leave it the worse it will get.

Would deffo think twice before spending any dosh on it.To put it in perspective after my 'C' went pop, i picked up a bare 'E'
for £250, much better box, the only thing you can't swap over from the 'C' is the ECU, but again they're cheap as chips
now.Everything else is a straight swap.

Are the C & E exhaust ports the same for the manifold?

Yes, most of the C to E mods are internal, the head casting is the same, its easy to spot an E as they don't have a cam sensor and the hole in
the head for one isn't machined, you can see where it would have been if it had been used on a C during manufacture. All the ancilliaries are a
straight swap, i didn't even have to rejet the carbs. The only problem is the ecu, its smaller and has a different loom plug (due to lack of cam
sensor). I guess an electronics bod could get round it and use the C ecu, but i picked one up for £25 so couldn't be bothered trying.

Thanks for the advice.
I’ve had a chat with the local Kawasaki mechanic and he’s confirmed it’s not unusual to have some swarf in the sump form the gearbox, he also said,
that if it was the shells, he’d expect more metal to be present than what I had in mone. So the logical assumption is it’s from the gearbox (panic
over!).
Taking Hellfires and Wadders advice I may look out for a cheap second motor as a spare.
Once again thanks
Ian
