picked this basket case up for $150 tonight. Got it to start one for about a few seconds, lagging throttle response and almost sounded like it was running on 3 cylinders or something.

Got it home and now it wont start, turns over and after about 20 seconds or so I get a very loud pop from the exhaust.

I need to go get pods for it tomorrow. Any thoughs on where to start?

previous owner said this of the carbs in an email to me.

"In this picture it has 4-1 exhaust. But since then I have cut it, and made it into 4-2. Reason being, it was running to rich, since I drilled out the jets. If it had 90 jets, it would run better. One of the carbs need a float needle. As far as the diaphrams, none of them are cracked or torn."

any thoughts

thanks guys

He DRILLED the jets? If you got it to run at all then most likely all you need to do is properly rebuild the carburetors.

WTF...jets are like $3 a pop. Drill them? ugh...

we would be guessing blindly. being POS that has been mangled by previous owner I would first clean the carbs (needs to be done 99% sure anyway) and try to get it back to stock in terms of airbox and intake + jetting. Trying to react with tricks to unknown tricks doesn't work very well. get a manual and try get it running right. Doing this for a stock is much easier.
As getting stock jets and hunting down airbox already takes money and effort you will quickly just go deeper into hole.

Part it out, sell on ebay and buy a bike you can ride. You'll get your money back and will have less head aches.

I think he's full of shit, because I think the KZ750's with CV carbs came stock with something like 125 main jets.
I also think if one of the carbs "needs a float needle", you will be dumping fuel into whatever cylinder that carb is.

I think you'd be wise to get reasonable pods, such as Uni's or K&N's. Not cheao,

I think you should get 127.5's and 130's for your main jets with those pods.

I think you should do a complete tune up. You know, like valve clearances. I do believe that bike is bucket over shim.

Figure out what shims you need first and pick them up when you pick up your Unis or K&N's.

Listen to these guys!!!! Trust me. I speak from experience.

You can probably get a lot of what you need from Mark, the guy above (mlinder) he has an online shop.

If I were you though I'd bail on the pod idea. Just my personal opinion, and it's over done.

You have carbs, exhaust and air intake to consider. One changes the other. You can go online and find the info you need until you can get a manual (get one). Once you know what is stock as far as jetting goes order 3-4 sizes up and down so you can tweak. Jets R Us has them as do other vendors. Carb rebuild kits do not come with jets. Clean your carbs and then clean them again.

I don't know a whole lot but I think that bike has potential. And for $150 you're a little ahead of the game already. I'd get it back to stock (exhaust, carbs, air box) and get it running right and go from there.

how does the raised rear end with new shock mounts work out? Seems like horrible for the geometry with reverse progression...

and those welds are not too hot either. Seriously sell, forks, wheels and tank + engine and you'll come ahead. I am not trying to be overly negative but it will take a fair bit of effort to fix damage done by fools and doubt the bikes value will go up that much.

Does it have a title? If not, it's probably not worth fixing.

Part it out and you should get your money back at least.

Those stock shocks with the "revised" geometry are causing the rear end to be waaaay too soft and there is no (visible) bracing for those re-located upper shock mounts. The wiring looks a mess.

The guy had a drill and a few minutes of redneck clarity and decided the bike was running too rich and needed MORE fuel?

Kenda Challenger tires - great for MSF training bikes (I use them on some of my fleet of trainers), not so much for road use if you treasure traction in curves above 12-18mph.

On the plus side, no checkerboard, no clubmans, the front fender is still there. The frame is junk. The harness is junk. The engine...may be salvageable with some intelligent application of time and tools. Your call.

Can you weld at all? Any fabrication experience? The bike really doesn't seem so far off to me as to abandon. If you were near I would be very willing to help you get it straightened out properly.

I do live in STL and am asking 450 for it. Also with that ( and I knowingly bought it and am selling it this way) , the title has the title holders signature in the sellers spot, along with the date from 2006. thus to title it would carry a late penalty. how ever it is still easily able to be titled.

chetriply, email me at [email protected] if your interested

I love KZ750's but it would cost me a minimum of $200 to get the bike titled in my name and with your asking price that would put it in the $650.00 range. Being as I am a cheap bastard, I couldn't go that high. I do miss my last one though.
