stripping zzr1100 carbs
blakep82 - 22/11/07 at 09:56 PM

anyone know where to d/l a manual for the carbs? mine arrived today and could obviously do with stripping down and the jets drilled. but i like to read up on these things well in advance.

what i *think* are fuel pipes seem to have loads of take offs at every join. don't really understand that

This might help, got it from a similar cry for help. Rescued attachment zzr110 carbs.jpg

mine seem to look a bit different! i'll get a picture of mine up later!

here's what i got! £20, so there's bound to be a few things missing

lol! now i see them side by side they're the same!

the heater pipes, are they plumbed into the coolant pipes in the engine? why does it look like the heater and fuel pipes join into a common 'rail'

Have a look HERE for a download.

Might be useful.

If you can hang on until after the weekend I can photocopy my Haynes manual and pop the relevant bits in the post to you.

I'm at work at the minute, and the manual is at home!

Your carbs are the same as in my pic.
The heater pipes connect to the coolant flow, but, discard them for car use, they were used on the bike cos of the draughts created on the bike forced induction - intakes in the fairing.
on carbs 1 & 4 water is on the outside connection, on carbs 2 & 3 its on the inside connection, the other 4 connections (two T's) are fuel.
Yes they look like they are on a common rail, but if you pull the water connection out, you will see the carb drilling goes nowhere, and the brass union you pulled out has an in/out arrangement to warm the blank hole in the carb - sounds daft but thats how it worked, just enough to prevent icing, but just junk all this, nothing to blank off.
The connections between carbs 1&2 and 3&4 seemingly on the same rail is fuel in.
The other two connectors between the same carbs is air in, needs connecting to airbox, or, as on the ZXR750 just a couple of pipes pointing downwards.
Cheers.
Pete.

Neil: Thank you for the link! I don't speak russian, but i did manage to find what i was after! Thank you for your help!

Mike: Thanks for the offer! appreciate it, but as above, i've got some copies of it now!

And Pete: Thank you for the diagram! it really clears it up a lot. I gather then, that the pipes round the butterfly side of the carbs are water pipes too?
what do the 2 air pipes do? and do the have to be filtered?

I was considering individual cone filters for the 4 carbs rather than an air box (tight on space really) so could i connect the 2 air pipes together with a T peice, and use one of the small breather filters? or not use a filter at all on them?

Yes just junk all the water pipes, they create hot spots in the carb, there is no 'circulation'.
On the ZXR750 (CVK Carbs too) the air pipes just point downwards, on the zzr they go to the airbox.
You would be better off with an airbox than individual filters, there are ports on the filter side of the carbs which need filtered air too, best to try and get hold of the air filter mounting plate and trumpets, I'll post a pic of that bit....

thanks Pete!

what sort of angle are they supposed to be mounted at? or does it not matter?


r1_pete - 23/11/07 at 06:14 PM

The carb to float bowl joint should be horizontal, which puts the carbs at about 35 degs.
Here's that pic of the airbox connector.... Rescued attachment airbox bit.jpg
