VM 28 or VM 29s

[Lee McEvoy]

Is there a way of telling the difference (without measuring the insides) between the 28s and 29s?

Thanks

29 smoothbores have this little square casting on the side

[Pigford]

YES


Easy difference is the top cover - the 29's have a "keyhole" shaped top

GOD I AM SLOW AT THIS !!
Lee,
One of the signs of 29mm Smoothbores is if you look on the R/H side on the body just above the float bowl- you will see a small square recess in the body casting.

I thought the 29's have a hex nut on the float bowl to get to the main jet instead of a drain screw

I do not think he meant "smooth bores"

The 29mm only came as smoothbores.

I always thought that GS1000 S used 29 mm ? but it would not be the 1st or last time ive been wrong

Thanks for those steers. Looks like I have the VM29s



Although not sure about the key hole tops pigford talked about.

Sorry about the photo

Lee,

I think your engine is in the frame the wrong way??

Gs1000 used either 26mm or 28mm slides depending on model before going to CV's.
The 998cc homologation Katana used 32mm smoothbores (the 1100 used CV's)

i recently got some gs1000 parts and was told 1 set of carbs where off a katana 998cc does the inside of the carb body change into an oval shape rather than staying round all the way through??

There were some Katana carbs that had oval throats.

Yes! They are oval at the venturi.
