Low personal B.M.E.P.
As an egine builder I am concerned...I first saw this in a GSXR1100 on alky with Rob Holden riding - he worked the chassis hard enough we saw strange wear markings on the outer mains. The early 1100 chassis weren't particularly stiff and the motor was tied in pretty well so any flex showed up in the cases.
Given you have a Kawasaki I'd definitely be concerned. From the pics as far as I can see yours is different to the early ZX/ZZR series as i can't see a bolt in main bearing block so it may be better. Has it still got the Kawa drawback of one main feeding two bigends ? Nothing you can do about that. i used to put in a Mr Turbo mod of a direct oil feed to the bolt in block from the oil filter outlet via a hose and bulkhead fitting through the sump with a quill direct to that block.
Good luck with the pickup - get it wrong and it's good night nurse....I really don't like a cut sump on these. I drysumped one for a speedway chair which worked well in that application but when the motor went into a roadrace chair and things got moved round to suit it never worked as well again....

Sooooooo, 'she'll be right' isn't how this works? BUGGER!
Chair was built around an 1100r before the 12 went in as it turns out, so as long as the last owner didn't mess about too much with the chassis we might be good to go. (We has a short think about frame rails over the motor today. Wouldn't need to be massive to stiffen things up sufficiently).
One main oil feed, on flowing two big ends may indeed be the case. I'll have to take a closer look, but there are two small feed pipes in the sump area and I'll see where they go. Thought they were input shaft sorta zoned.
The off the shelf dry sump kit is a bit out of our price range. Perhaps Kai could have a think about selling the setup he has going begging.
My thinking with the oil pickup, relies on the sump volume increase being sufficient really. The low bit that's been lopped off has more than been made up for, (reckon I might get a jug of water and double check that on the morrow), but there's always a danger it's not enough.

With a wet sump sidecar, it will either last 20 years without an issue, or it will fuck itself on the first outing. Are you a betting man?

Other people have already done that
Burt did two or three Blackbird cranks and I thought at least 2 GSXR cranks, Phil Law was the only person who had any success with the Blackbird, if it wasn't for a puncture at Teretonga he would have had a NZ title with one

I'm not in the financial position to start betting a motor.
Pate gave me some very helpfull advice about the baffle design, I'm just wondering if there might not be a few other things I can do to ensure we don't put windows in these casings like the last ones.

A dry sump kit would be a good start http://www.muzzys.com/ZX12_Dry_Sump/index.html

We've already looked at those. Did you notice the fuckin price? That's over half what the outfit cost.
I'll see what Kai says about selling what he's got, with a look to adapt it to the kwaka.

I dont remember the Kawasaki we ran having anything special done to it and we had the sump off that more than once, Dave ran them for a while so he'd also know what to do with it

Can you text me his number then. Email would prolly be easier.

We always add power up to the oil as extra insurance.
Hey, dont fret too much, I think the 'busa is the only dry sump sidecar out there.
Sometimes a new engine will turn up on the scene & a number of them will be destroyed before someone hits on the perfect sump. The '00 R6 engine was such a case.
Saving the goat....
What year was that?
Is it still beastiality if ya fuck a frozen chicken??
i'm motarded
What a top bloke

The thing which made the earlier ZZR a hand grenade was mainly the separate bearing block for the main alongside the primary...which also fed two big ends....and was fed itself by a twisted piece of small diameter tube.
The Mr Turbo mod made the cranks last but oil surge from bad sumps then killed a few...
Yours looks from the pics to have a common rail type oil feed and no separate bearing block which should be better.
I note that overfilling may not be an option as the early 1200's were sensitive to oil level - too much and they wouldn't rev
Shouldn't worry a novice though...ride it on the torque curve.
If I had the motor I'd be checking clearances - aim for 1.6 thou mains and 1.8 thou big ends - and check the relief valve lift pressure.

You're trying to tell a Mair not to thrash the shit out of it ? Bwahahahaha
He told me the optimum method of upshifting on the SV was to preload the gear lever and wait for the rev limiter.........
