OK, lets start off by saying hello.
and lets get greasy....
i'm not a mech. but i can give you my fixes..
(no warrentee implied)

probs. i have fixed...
1> seems a lotta old kawasaki's wont start in the cold..
well come to find out most have to tight valves and if you adjust them
all your starting probs. go away..
i have fixed 2 this year ..both hard start.. both valves tight..
see ...the tight valves stay open ever so slightly
and you get limited compression.
so good lluck there kaw. guys..

2. here in the valley we destroy(because of heat and dry)
vacuume lines and fork seals.
Replace yours .....your forks deserve it... easy fix...

i have a gsxr750 1989.
looks like dude stuck on 40mm mikunis.
i figured out the fuel
i figured out i assume the overflow tubes (come out bottom front)
but there is lines off the top front(t-wards cyl)
i figure they are vacuume lines.?
do the y and go to tank fuel stopper?
also on this model the head vent .
do i throw a lil tube and breather on that?
shop manual is due tomm.
but i want to see if i can do it without book..
Thanks bro's and sisters

Funny, we have one of those in our shop right now.

I'm assuming you mean the lines that come from the top two outside carb diaphrams? That one goes to the fuel tank.

Most crankcase vents just have a tube that vents to the ground. It's there so that the air displaced by the pistons has someplace to go when the pistons come down, and a way to return when the pistons go back up.

i figured...
but was not sure..
I might after making this run.
need to get a good tune on carbs.
got a tuner to recommend?

We use a Carbtune rod style tuner for most bikes. Some, we have to use an old cup and ball style. I hate those.

thanks for making a new thread...
i got the lines and fitting to do the carbs and fuel tank.
waiting for it to cool and i'm gonna do it in back yard.
oh also.
it seems dude put a 86 ignition box on the bike.

connectors are correct.
ty bro..

They are different part numbers for the signal generator between 1986 and 1989. However, that doesn't always mean much. It might be something as simple as a difference in the resin used to seal the thing.

im still wondering where they got the 40mm mikuni's from.
i thought maybe a gsxr1100.
also bike does not have airbox.
it has the steel mesh old school
so this could be a jet nightnare
or a hidden gas gobbling monster.
well see...
oh. you sell turn signals ect at yer shop?
cheep mini aftermarket jobbers?
need fronts and backs..

Are you sure you have 40mm carbs? 750's had 38mm, USA 1100 =36mm,non USA 1100=40mm. I know it's stupid, 750 carbs are bigger than 1100 but thats Suzuki . If you think there to big for your bike you might be able to convince me to take them off your hands :rolleyes:
