Hi, my UK A9 GTR1000 has developed a big problem! Its done 86K miles and is getting very noisy, when cold it rattles like hell but this soon settle down and it runs really well...but!
The outer RH engine casting next to the outer exhaust stud has cracked. Probably been over-tightened at some point and has driven the stud into the head, making a hairline crack. I noticed a slight oil leak when I bought the bike earlier this year, but assumed it was the cover gasket leaking, sadly not! :(
I'm now considering my options, as its a bit noisy and now leaking oil, what engine can I use to replace mine? Do the chain driven engines fit, is it possible to swap over the final drive parts/engine cases?
Or, what cylinder heads could I use, I don't really want to make a full blown ZX10 type of high revving motor, saying that I've already got the higher power carb tops and Neta exhaust.
I'm on a tight budget due to being out of work with health issues, I need my bike back on the road :'(
Thanks in advance, all ideas greatfully welcome :)

Others can chime in, but I think that most of the chain driven engines do not share the same frame/head mounts.
Plus converting the frame from drive shaft to chain would be added expense of components.
So the best engine to buy is another Concours.
I know their are fewer of them in Eu than the USA, but still the best choice.
NOTE: Any year Concours engine will fit your bike.
Try contacting members of the GTR or GCE.
Boomer is in your area (I think). He may know where to get an engine.
Ride safe, Ted

I want a replacement engine, I can't find another shaft drive unit. I was asking if its possible to convert a chain drive engine to shaft?
Surely the crank cases etc are the same, I'm looking at the possibility of removing the final drives and swapping them round. Depends on how the shaft drive is connected to the gearbox, I'm thinking that Kawasaki wouldn't of built a totally new engine just to make the final drive shaft and not chain. I've no intention of making a chain driven GTR!
-
The 86 / 87 ZX1000R (usa) motors (long block) are the same except for the cams. You would need to use your carbs and carb to block boots, and your bevel drive and then I believe it would then be a bolt in swap.
If you want the same lower RPM performance, you could put your cams in and then it would be just like your current engine.

Hi turbojoe, thanks for your reply!
I can get a ZX1000R motor, but its chain drive, like most engines that are the same range. I would fit a complete motor if needed, there's not a massive amount of difference between them in the real world.
I've not got any experience in converting a chain drive ZX motor to shaft drive, do you know if its a major job? Does the shaft drive box just fit onto the same chain drive output shaft? I would like to think so!
Thanks again, Happy New Year to you all,
Mike

Is the ZL1000 Eliminator the same motor as the C10? Looks identical and I'd have thought it would be the downtuned version?
-
Eliminator engine is almost identical to a GTR1000 engine. Carbs are different as are camshafts and final drive ratio in bevel drive is different.
You can convert any of the GPZ900 / GPZ1000 or ZZR1100 or ZRX1100 chain dive motors to shaft drive using your gearbox components.
All depends on your budget and time / skill set?
-
Thanks again:
I can complete any amount of mechanical work: not being clever but been building engines for over 30 years!
I think I'll look for a ZX or similar lump, I was sort of sure the final drives would swap, simply because Kawasaki wouldn't make an entirely new set of engine cases for a shaft drive of limited numbers! ;D
People say I will lose midrange, but in the real world, any 1000cc zed will have all the midrange I could use, top end speed isn't a big point but a little better acceleration would keep me smiling :thumbs:
-
Just noticed something!
I can buy a 1988 ZX10 motor at a great price, but it has an external oil pipe from the lower front case, up to the RH side of the head, next to the camshafts. I can't see this being a problem, but its just making me worry a bit...also, I would swear that the inlet cast stubs are at a sharper angle than on mine, I'm only looking at pictures of the ZX motor so could just be me :-[
The ZX motor also sits in a full frame, but the GTR as you know hangs from the frame as a stressed member...bit like me right now! :P

Technically with enough imagination, money and skill you can use (within reason) any engine you want! 8)

Thanks for your input Rhino :rotflmao:
Can you advise how I tie the shaft drive assembly to the shown donor engines? I really like the radial motor :P
-
Saying that, the Lambo running throttle bodies must sound amazing!
These builders are something else, wish I could build motors like they have :)
-
Where in the UK are you?
I have spare barrels and pistons that you can have if you want them?

Just found a whole motor on Ebay for £65 !

Jacksdad, look closely at the photo's Vinny sent.
Good photo's!
At the front of the head, {just below the valve cover} you will see the Frame mounts.
I do NOT think the ZX-1000 engine has these frame mounts.
That is why I said, the ZX-1000 motor is NOT an easy fit for your Connie.
You must replace your engine with another that has these frame mounts.

that's an no brainer for the price... man, jump on it...
all ya need is the head,,,, and then you can send me the valve cover..... hint, hint, 8)
seriously, even if you needed to do a valve job on it, (regrind, and new guide seals) it's worth it.
-
Hi Ted, thats exactly what I'm concerned about: I said in my post above that the engines are fitted in different ways!
You have got it spot on...the alloy frame engines are indeed different in that they are carried within the frame, not suspended from it, and the mountings are different.
-
Ive contacted the seller to see if they will pallet up the motor for me to get collected, its a 600 mile round trip for me to collect, would cost more than the engine is worth.
-
GPZ1000RX and ZX10 have got the extra upper engine mountings on the front of the head, ZZR haven't, seems that the early full frame bikes just didn't use the mountings, or they were used for fairing mounting points. So an engine swap is still an option, but not as easy as at first suggested!
-
What's it worth if you need one and don't have one?

-
Its also done 90k miles, so maybe I'll keep looking:
It looks like the 1000 engine with external oil pipe is a 998cc and doesn't have upper engine mounts, won't fit. the 997 engine has internal oil supply and does have upper engine mounts, will fit, just my idea so far :D

I refrained from making comments on the "other" forum, about the idea of transposing any other engine into a ZG, than a ZG engine, but have to laugh out load about this after reading for days, the thoughts about "that project" and ask, are you serious?
I mean you were talking about a couple thousand dollars of retrofit and conversion processes, and now, it cost's too much to jump into a car, drive half a day, toss an engine in your trunk..(or Boot, as you folks call it) and return home...
hell, we hold weekend rides where we ride these silly bikes from point "A" to lunch, and return via a different route, before dark, and embibe...when we get back to point "A"...
a shipper here, picking something up en-route, and dropping it off from a 600 mile trek, costs a bunch more than any gas price to do the same in a pickup truck here getting 20 miles to a gallon of fuel.
best of luck tho, you got a great price on a part, best of luck swapping it out, and really glad you won't be trying to adapt an engine into the bike, and asking for mega assistance from people so far away, to give you explicit directions for the process, which in the end, will cost approximately what that bike sold for new.
-
its done 90000 miles, and the fuel cost alone is £200, I can get another model engine thats done 40k, for £125...if it will fit.
What if I spend a full 24 hours and £200 fuel, then strip it, and find its fucked? do I take it back for a refund, at best, as thats what I would be told to do, by law.
Where do you get "a couple thousand dollars of retrofit and conversion processes" and "will cost approximately what that bike sold for new "
from: It would cost me nothing to do myself!
There's also the idea of doing a conversion just to do it: I'm a skilled motor mechanic, and do this sort of job on cars, 4x4's and bikes, but not having done this exact job before, am asking for advice...and not smart arsed comments from some ***** who has nothing helpful to say.

Indeed. I don't normally expect this kind of shenanigans in the C10 boards. C14 yes, C10 no. I think I'll let T or Rick sort it out.

Nothing to sort out Jim since the sage advice from the smart arsed ***** while spot on was not well received we can just leave the topic closed as a guide for what to not say or do on the forum...
Good day to all...
