z1000 mk2 using tm33's

Hello, I've just joined the group and would welcome jetting advise from anyone running tm33 flat slides on their kz1000. I've aquired a set off of ebay from an english gsxr750 from around 88 or 89. however their not performing as they should. Apart from the first carb from the left being totally blocked (due to the choke slide being broken and jammed on full choke) I've just noticed they're running 97.5 main jets. (30 below stock). I'm waiting to find out what bike these were actually used on last. Well to get to the point. I've fitted these to a de-shafted 79 z1000st (english) with a standard bore size 1015cc with a ported head to suit these carbs. Could anyone recommend what main jet's I should use for this application ? i've heard that the stock 127.5 could be too large for street use as they'd regularly choke-up in traffic on the late eighties gsxr's they were intended for. Thank you. simon. newcastle upon tyne, england.

Sorry, can't help you with the jets and such on those carbs but I am very interested in the de-shafted E!

Care to post some photos of that?

Oh and welcome to the forum, no toga required!:lol:

I'd start right there with the 127.5 and see how you make out. Better a little fat than lean

These are the best pics I could get in my cluttered garage but should have it on the road in the next couple of days. I've just put 120 main jets in out of my vm26's making a vast improvement. The only problem I now have is the third and fourth pot are getting more fuel than the first and second. I think this is down to the choke having been stuck on full on the first carb causing the pump piston to seize up. I've cleaned it up but its not performing as well as the pump in the fourth carb. I've still got to paint the bike (probably black) using the white ltd tank instead of the original. Thank you. simon.

Thanks for the info leon. Thats how i've been trying to download pics but for some reason it keeps coming up something about exceeding the megabytes for a file download.

Although oversize images are usually automatically reduced and shown by KZr, try reducing image to these limits:
Width: 2400px
Height: 1200px
Size: 2048kb (2 MB)

Don't know what's causing the "fakepath" image name.

Good Fortune!

97.5 are the stock 1988 gsxr 750 mains
you have a lot of room and opions avaiable to play with these carbs
GOOD CARBS ARE HARD TO FIND
you have found a set

PS if you are gonna put these old GSXR carbs on a KAWASAKI
I would first introduce them to your KAWASAKI gently
Make sure that the KAWASAKI dosent just look at them and say
"Do I really wanna make a suzuki fart?"
I remeber being on a hunting trip
I rode my old KAWASAKI to the tree stand
Just as I was about to shoot a 12 point buck
I saw something out of the corner of my eye
It was my KAWASAKI killibg a family of young suzukis
Anyway I let the buck go and observed the natural order of life
