doesn't look to me that the calliper is sitting correctly on the disc -

These are the things I'm not sure of, I put some tape on the disc and marked out the brake pad where it would sit and it looked to be on all of the disc! maybe I better take a closer look, as you said, it shouldn't line up with one bolt in the original fork, (I would sooner buy a set of plates made up, But I am too far from any engineers, I also have a rear caliper that needs a bracket but that is well beyond me,

Are the lugs on the fork flat enough on the outside?

They seem to be, I ground an angle on the plate so it would sit tighter and flater to the main fork leg,

my original calipers have broken nipples, stripped threads, and seized a bit etc,

Thanks for reply, I just found a link here where they use 10mm plate,( 6mm does look a bit thin, )but it doesn't show if he uses a loose spacer or its welded on

Hi,

I am trying to change my 1980 gs1000 front brakes with a set of Tokico calipers, I have made a rough bracket,  1. is the bracket big enough? 2. stainless or aluminium 6061-7075? (I have no idea what the plate I used was), 3. should I have a spacer made (4) and welded to the plate for bolt #2, any advice please,

Sorry to confuse the issue, the carbs are off a z1000 ltd 1983, I still have the engine (and thought the engine is the same as a 1000j as I tried the carbs on a 1000j 1982) I tried the them on the 1980 gs1000 but the rubbers seem to block a bit of the intake flow,

Hi,

Thanks for the reply, I bought a 1980 gs1000, in bits, the guy had made his own intake plates and cut some 34mm rad pipe, but there's not enough on the intake to get a good clamp on for the vm carb, also it looks like the mixture screw has snapped off and it wont push out, so I have an old 1000j set of carbs I was going to try but need to find the rubbers to fit. Can't seem to source any gs1000 cv rubbers that are not over 150 quid.

Since learned the VM & CV head spacing on GS1000 is different.

Also that a KZ900/1000 pre 79 rubbers should work.

Ordered a set so we will see???

Hi, did the kz900/1000 rubbers fit the CV head and vm carbs?

[GS1000 CV to slide carb mod.]

i took  a set of mj 95 of my other gs 1000 carbs and tried them, it ran rough, sounded like fuel starvation, although tick over was higher? missing and back firing. i have a good set of cvs of an 83 kawasaki  1000j, i read that they might fit on the 1980 cv gs1000, they look like 39-40mm od on the intake with 35 mm spacing 1-2 +3-4

and 56mm from 2-3, anyone know what size the intake rubbers are on the cv gs 1000? i have seen the conversion intakes, slide to cv but cant get any sizes for stock cv intake rubbers

No mixture screw on base, so not suzuki carbs?

Are the MJ 145 Mikuni?  Because that would be really rich. Should be around 125.

But, are they Dynojet MJ?

Since the carbs aren't stock, some pictures might help

I will drop the bowls and re check the main jet sizes, will also see if the intake on number 1 will vacuum,

Thanks for your replies, Hope to get some photos in the next day or two. I also bought a 1978 gs1000e which is pretty stock, apart from 4:1, but the carbs are a mess, being stood for 20 years, they have the vacuum pipe between 2-3, I have stripped them right down and have a kit coming, they look like stock 95 main jets, although everything is a bit rusty and faded.

Never felt right leaving bike on prime while running, like the idea of sourcing another vacuum from the intake, 

Changing the subject, I have just seen these carbs off a local marketplace, just says kawasaki mikuni's, don't think they are 650, but seems like a strange box under number 2, would that be an american emisions thing? guy asking 150 euros 

[GS1000 CV to slide carb mod.]

Hi,

Bought a basket case gs1000e. The head is a 1980 model, with home made plates with rubbers to take slide carbs instead of cv's,  K and  N filters and 4:1 baffled. The bike runs smooth on tick over and clean gear changes (slow build up) at 3500rm up to 80mph then struggles, coughs and splutters. I noticed the jets are 145, would it need this size because of the bigger intake and the modification? The carbs do not have a vacuum supply between 2-3 carbs but the tank fuel tap is not on/off type so I run it on prime with an inline on/off tap, would this make a difference? I don't know whether to try and lower the jet sizes or just source out a set of rubbers and cv carb. I took it for it's first test drive today 50 miles, will check the plugs this evening to see if they are too rich,

any thoughts please,
