1977 gs750B jets

Andrew..If they arent VM 26s and you bought the stock size jets for a 26, remember to keep your new ones and put what was in there originally back.. youll need the stock ones for the right carbs!!

Yeah i remember. At least if i have to get other ones i will already have all new parts to go in after i clean! Trying to stay positive. lol

And there is not an area like that on the other side of that one or any other ones..right? Well thats not any VM 26 that i am familiar with..Measuer the engine side like i said when you called..Got my curiosity going now!! The measurement will tell the story.

[HighCountryGS]

No, the other side looks completely different. I wish i had something that i could measure with right now. But, am i safe to assume that nothing but the VM26 will work? obviously if they were too small they wouldn't work i guess.

[chuck hahn]

heres what i think..Cold beer..shower.measure tomorrow and i am sure others will be along to help also..

[HighCountryGS]

I am already into the beer, my friend. Maybe someone can help out too, as you have been a great help. I believe i will call it a day, or.....tear apart the rear caliper????

[chuck hahn]

Well i dont know what it is, but i know what its not!!!

[HighCountryGS]

So i measured them and they measure to be 26mm so..........

[chuck hahn]

Someone else will have to fill in the blank in my mind and yours..How about a shot of the front and the other side as well so everyone has a pananaramic view..may or may not help but what ya got to loose?

wonder if they are race type carbs, with the idle circuit and pilot fuel circuit combined.
the tower on the bottom is too short and the fuel screw in it is knurled like it was meant to be adjusted frequently by hand.
(edit) possibly off a snowmobile or 2cycle bike

at any rate thats not a stock 77 750b vm26, although that doesnt mean it wasnt stock on something else.

[chuck hahn]

Andrew..I wish i had a answer for you. Hope someone comes along with it and can get the bike back on track..

[HighCountryGS]

Yeah me too. I have everything new to get these thigs back together, but no sense if they are not going to work on my bike. On the other hand they are 26's. I wish someone could just tell me.

No. Those are stock. Some ass hat has installed aftermarket fuel screws becaus the OEM screws are NLA. Your pilot jet is too big if youre running a stock pipes and airbox set up. Those screws are incorrect. Get rid of them. Someone here has some for you I'm sure. Maybe me. But you'll have to wait till I get moved to find em if no one can help you. Those screws are for VM28 pumpers or 29 smoothbores. Check that the point hasn't broken off in the body.

[chuck hahn]

So your saying those are VM 26s..So where are the air screws at? Thats what has me puzzled. Dont look like the VM 26s i am used to. Anyways he has soaked them and done all the work up to this point.. I think he may need your insights here.

Good catch. Those may in fact be VM28 pumpers. I'd have to see the rest of the rack. Do they have an accelerator pump? Is there something odd hanging off the bottom of em? Bodies on all three are nearlythe same. But you're right. No air screws
