VM29SS on a 78 GS1000 advice please

[Agemax]

Finally got myself a set of these very hard to find carbs. slightly dirty (as expected) but good,unmolested condition.
A few questions for any of you guys that have fitted these carbs to a 8 valve GS1000.
1; what inlet rubbers do i need?
2; what K&N filters fit, with no clearance problems on the frame?
3; in conjunction with a Harris race pipe, do these carbs need a DJ kit or are they easy enough to tune/set up without it.

TIA.

1 they are a tight fit into your standard manifolds as long as manifolds are supple
2 K&N oval pods fit fine make sure you use filter oil on them
3 wash your mouth out..DJ... you get jets and jet the bike oldskool style

what jets are in the 29s now i would expect you would run around 110-115

You use the stock rubber inlets. Don't forget to grind out the inner diameter to match the 29mm bores. If you don't port the manifolds then you will restrict the flow and you might as well just keep the 26mm stock carbs.

thanks, the main jets in there are 130's. i do not know the history of the carbs so can only guess they were being used with pods on the gsxr750? hence the larger jets.
you think 110-115 mains will be big enough?

these are VM29SS, not 29mm smoothbores. the bore i/d is 33mm.

i am running VM28's at the moment

[ozman]

well that throws the cat in with the pidgeons
i thought you were talking about smoothbores

Those are the ones that are made for Kawasaki 900/1000 heads with oversize carbs. That is why you will have to slot the mounting holes to fit the GS head.

so they will work on my head then, if i slot the holes?

Those are the ones I was using with my VM33's. They have been opened up to enhance flow. The holes only need to be elongated a few mm's to fit the 1000 head.

great, thanks for the info Daryl.

now, back to the jets and filters. any ideas from experience anyone?

[TeamDar]

Yep, that's even what the ebay auction says.

maybe so, but i dont trust listings like that unless i know they have been tried and tested!

[Fjbj40]

My VM33's are using 130 mains, 17.5 pilot with a .6 air correction jet. Mixture screws are out 2.5 turns.

Not sure if it's of help but that's what I am/was running.
