Kawasaki Sportsbike Riders Club - Australia - Online Forum

Aye guys scored a J1 zxr750 for a decent price and am trying to sort out a starting problem.

First Kawasaki ive owned should be something different.

The story of the bike is a little vaig but i know its been sitting for about 12mths.

It was apparently ridden to its resting place and then left.

I have pulled the carbs off pulled the pilot and main jets out and and cleaned them i have blown every thing i can see through with a air blower as well as well as cleaned the float bowls and had the slides out and checked as far as i can see everything.
Ive done this twice.And they look very clean.

Ive had the plugs our and cleaned them and put them back in ( yes i know tight arse)
i was unsure about about the fuel pump but after having the carbs back on they filled with fuel so it must be pumping fuel to them.

When i'm kicking it over there is nothing at all- if i spray "start ya bastard" Straight into the carbs it will fire brefly.

This then tells me that its definately a fuel issue.

Am i missing something??

Anyhelp will be greatly appreciated, i'm going nuts

Blocked emulsion tubes? Something is starving it if start ya bastard gets it to fire. It's gotta be a blocked rooster somewhere! Keep cleaning!

Cheers for the feedback it wasn't the emulsion tubes after all, all sorted now- with out having to remove the carbs again.

My GPZ900r is doing the similar thing. What was the problem and solution?

Got some great info from some very helpful Kawasaki riders on another site-as you can see got nothing here.

You need to fill the float bowls right up or it wont start.

This is what i did and it was backed up buy a number of others with zx6's and 7's that have had to do the same thing to get there bikes running after storage/ carbs out.

Simple as this:

* Disconect the plug from the pump to the main wiring loom.

* Run some wire's from the pos/neg terminals on your battery long enough to reach the wiring to the fuel pump - but dont connect anything yet

* Remove your fuel tank

* Use the fuel line from your tap to your fuel filter and put a small funnel in it on the tank side of the line the other end to the filter- fill with fuel

* Now hard wire your fuel pump with the wires that you have run from your battery

*Make sure you do positive/poistive negitive/ negitive -for obvious reasons

* The pump will free pump fuel to the carbs- you will need to keep watching the fuel in the funnel and when it gets low stop and refill it again

* you may need to do this 4-5 times until you hear the fuel pump noise change- it will slow and sound like its under load

* Now fill the funnel again

* reconect your fuel pump wiring

* Spary areo start straight in to the carbs

* Hit the start button and it should fire into life straight away.

Important note - i did this with the air box removed , it may be worth doing this so you can get straight to the carbs with the areo start.

It worked for me hope this helps you.

Cheers damo

Removed and cleaned, balanced and set float levels. Re-installed and tested, starts now but still fails when warm.
New leads and new plugs- Voila, runs like a charm, revs and doent miss.
