I have a bike on my hand here,but I need some advice:After the engine was overhauled,there was no oil pressure!So the dude is trying to sell me his bike cheap,as he has no knowledge of bikes(He said he had a friend overhaul the engine,he also claims the bike to be a "GSX 1000",which its probably not,since they didnt go into production until 2003...So I figured it must be a GS 1000..).What could be wrong,and is it much hassle to dig out the oil pump?I suspect theres an internal leak somewhere as oil pumps are quite simple made,and it must have worked before the overhaul..Many possible places?Could it just be "lag",that it takes some time to build up enough pressure to kill the lamp?I remember changing oil on my 550,took some time before the light went out..And shouldnt oil pumps be packed with grease when they have been completely dry?So I just wonder: Is this bike a potential gold mine,or should I just let it go?The dude says its nothing else wrong with it.(I havent yet seen the bike,but I wonder if its worth the travel...)

what year is the bike? they did make a gsx1000 in the early 80's, they made a gsx1000 katana. is it 8v or 16v?
what oil is in it, does the pressure switch work?
get a pressure gauge on the engine and check it.
otherwise it could be a dodgy oil pump or maybe even the dogs on the drive gears sheared/misaligned or even missing
 
also keep in mind that some of these engines (I don't know if that particular 1000 is one of them) only run 5-8 psi, max. If you have a typical gauge that reads to 100 or so, it might not even show up.

If you are relying on the oil light, test it to make sure it's operating properly. If the wire is off the switch, it will never turn the light off.

.
 
Mine runs at 2-3 psi at idle when at operating temperatures. This is normal according to my manual. So real low oil pressure for at least some of these bikes (as Steve said) is very normal.
 
Also, where are you on this big blue marble we call Earth?

Model designations vary somewhat by country.
 
Pictures really help too.

You wont find a greater, more knowledgeable group of experts than here as concerns the vintage GS bikes (I am not one of them---just learning a lot like you!)

Good Luck!

Gsx 1000?

Gsx 1000?

I am in Norway,but Ive searched both the world wide web as well as domestic pages,and the only GSX 1000 I could find was on this page: http://www.suzukicycles.org/ (see under GSX series) Its a picture of a brochure that is a clear evidence that the GSX 1000 Katana exists!But that was the only one I could find,apart from the 2001- GSX 1000R,so it must be a rare bike.This page claims they have all Suzukis ever made,and all the other are 1100's!
 
to answer the question of getting at the oil pump. It is not difficult and would take less than an hour and a couple beers. The clutch has to be removed to remove the oil pump.
I just replaced the oil pump on my 1100LT, put it all back together and started her up. NO pressure. Tore it all down again checking as I went and found nothing out of place including the pump gasket. Put it all back together, started her up and wa la, pressure. One of the fellows in the NW group thinks that it might have been an air lock.
Go Figure.
