1978 gs550e bigger car question

[Darthjames21]

anyone know any other carbs that will swap from the vm22s to a bigger size? my buddie has a set of vm28s from his z1 but the spacing for the boots to the head is way off. or is there any other boots that would work also to swap bigger carbs? i have been searching google but cant find any info. i want bigger carbs because im building my bike for drag racing and after i do pistons cams and little other engine work i wanna not be maxed out with the vm22s. thank you.

I've put Z1 carbs on a Z650 - and the 650 carbs on a big CB400....Which required respacing. It's possible to remount them on a 5mm - or 3/16in for you yanks - plate and redo the fuel joiners and throttle link rod. But it's a lot of work and if you haven't done anything like that before, I wouldn't start here.
Back in the day Performance Bike mag in the UK put carbs from I think a GS750 on to a big-bored 550. i don't think they ever got it set up properly.

Do it properly and use aftermarket carbs like 29mm smoothbores - or a late type like Keihin CR's or Mikuni RS's. You will then be able to get alternative needles - which you won't for the Z1 carbs. You will actually stand a chance of getting it to run properly.

You can use the VM24's off a Z650 which are the same inlet stub size and will fit the Suzuki inlet rubbers.
If wanting to use the VM26/28's the actual carb spacing is the same and if you are handy just make an adaptor plate to take the correct mounts..
