Does anyone know of a GOOD KZ Carb Rebuilder?

Looking to have my KZ650 carbs rebuilt.

I saw a few listings on eBay of ppl who sell rebuilt carbs or provide the service. Curious to know if anyone can recommend someone.

Thanks!

Good Fortune!

Have you adjusted the valves and done a tune up first? That must be done BEFORE going to the carbs.

What's the general condition of the carburetors? I would at the minimum remove them from the motorcycle, then remove the float bowls to take a look. Then using good fitting tools, remove the floats, main jets & bleeder pipes where the main jets screw in & pilot jets. and remove anything else under there I may have overlooked. Do some cleaning, then put it back together. Then decide if they really need to be sent out. I'd never really done carb work before but went ahead & did the complete disassembly & cleaning and dunked the carb bodies and I thought it was easy. The same thing is done 4 times on a lot of stuff & most parts only go back together one way, so it's kind of hard to mess up.

Personally I can't image paying someone to "rebuild" the carbs since they are so simple, but if you feel you must try the folks at:

In order to do a proper rebuild the carbs should be fully unganged and dissembled. Then soak all the hard parts in carb dip, paying particular attention to things such as the pilot jets, to assure all passages are open. Then reassemble the carbs using new gaskets and O-rings. And lastly they need to be leak checked and the fuel level verified using the clear tube method. All the jets can be reused unless damaged. Float seats and needles need to be carefully inspected; if the float needle spring can't hold up the weight of the float they should be replaced. Bottom line though is that they hold fuel back and the fuel level check will verify that.

Here is a VM carb tutorial that may be helpful. It's not super detailed but there is lots of good info inside... members.dslextreme.com/users/bikecliff/i.../vm_carb_rebuild.pdf

I couldn't agree with Ed more! Take your time, and be thorough. Don't over-complicate things and it will run great. Carbs really are simple, and they use some basic fluid physics in their operation. Where you run into trouble is when things get broken or plugged, or just plain assembled wrong.


And believe or not, that air box was calculated to supply the proper amount of air for your engine size.

There is massive quantities of information available at your fingertips on the internet. Does anyone remember libraries? I used to have to go copy this info at $0.10 per page to access it, IF I could even find it. The internet is like having a library in your living room.

If you're going to own classic bikes you better learn how to work on them. :whistle:
Besides, there is a certain sense of satisfaction and security in knowing what's going on in between your legs.

Exactly! Months of effort and tons of money went into designing an airbox that would provide maximum performance at all engine speeds. Keep in mind that when these bikes were built there was a LOT of competition between the various manufacturers regarding which bike was the quickest, etc. so the motorcycle engineers worked hard to gain maximum performance from the engines while still keeping the bikes usable on the street. Velocity stacks and other non-stock air filters may (MAY) provide more power at a given engine rpm but typically this will be offset by a loss of power at other rpm.

One other thing to consider - velocity stacks do not provide filtering of the air, so any road grit, bugs, etc. will be sucked into the engine and that will shorten its life. That may not be a big problem for a 1/4 mile race bike that may only be ridden a very few miles between rebuilds, but for a bike that will actually be ridden on the street it can be the kiss of death.

REALLY??

As said above. If you want to have the work done.
