Hi everone does anyone knpw if any of the gsxr1100 k,l or m carbs would fit my z1000j and if so if there would be any power increase. Cheers Nick.

The spacing is correct - BUT.......... lots of negatives :

The float bowl angle is a bit out.
They're CV type carbs and not easy to tune to suit a different bike.
Throttle cable position/fitting maybe an issue?

If you want more ooooomph from the cabrs - what tuning work has been done to the motor

Extra BHP needs proper engine work & exhaust & valves/head, etc.... Just bolting on bigger carbs is not always the way forward... and CV carbs are not ideal - go for flatslide or smoothbores such as Mikuni RS or VM

Nick,
I think you would be better with slabside 750 29mm flatslide carbs which work well on zeds.

Or like Pigford says smoothbores 29mm/33m depending on your engine spec.

Thanks everyone, I'll probably go for some smoothbores when money allows. I put my keihin 33's on about 15 years ago straight off my heavily tuned gpz1100 and this alone made a difference just on my standard J motor.

All GSXR-variants you mentioned, will use 40mm carbs, they are CV-flatslides and will have a too big body to fit onto the J-inlet rubbers. Furthermore you will loose quite a bit on the low-end and gain not much near the redline.

Get some VM29SS, if you want quick throttle response and low-end grunt or RS34s or 36 if you're more interested in mid to top.

Cheers,
Greg

This is what George recommends !!

Yeah, but swapping one set of BS34s on a Z1000J with another shouldn't make that much of a difference.

Sorry I was thinking of the 30mm VM's

Thought so... swapping in BS34s for the old (and often worn out) VMs is a nice upgrade to be honest.

Thanks again everyone, this has all been very helpful. Cheers Nick.

It doesn't make any real difference to any of what's been said, but I think the K and L had 36s the M was the first one with 40s.

I have GSXR1100K carbs fitted to my 77 Z1000A1. They work really well but as said the float heights and main jets need tweaking / changing, and you'll need larger inlet rubbers. I've had them on the bike for about 10 years now without any problems. If I remember they were fitted to a spondon (?) framed zed 1000 which featured in Streetfighters magazine, that was the first time I seen them on a zed.

The bike pulls like a train (1075 Wiseco) and the carbs are easy to balance. Use the standard throttle cable, but you'll only need one cable obvioulsy. I also fitted a high flow fuel tap. Hope this helps.
