I assume the bike in question is a GS850, from your screen name.

But what year? The 1979 intake boots are different than the 1980+ GS850.

And why do you ask?

In case you're wondering, there are no aftermarket boots that will work, but you can order new ones from any Suzuki dealer or parts source. They're about $20 each, and will last another 20+ years. There is no known way to repair cracked or hardened intake boots -- they must be replaced.

If you're replacing the o-rings, your best bet is to order new ones from Suzuki -- ordinary o-rings will quickly deteriorate in the heat and gasoline vapor environment.

If you're not sure what year GS850 engine you have, the 1979 model has a kick starter and several other small differences.

the year and bike is a gs850 -1985
i need some new inlet rubbers as 2 of them are split and might be leaking
have been offered a set of gs1000 inlet rubbers and was wondering if they would fit hence need to know the internal diameter of the inlet rubbers
thanks

After looking at flatouts's part diagram http://www.flatoutmotorcycles.com/fiche_select.asp

It would appear that your bike uses the bolt-on flange type, and the 1000 uses the double clamp style tube.

It would probably be best to find an online microfiche and see if the part numbers are the same. Even if the internal diameter is the same, they could be offset by different amounts. The last year for the GS850G in the US was 1983, so I don't know where to check for later models imported to other countries.

I'm just guessing, since you haven't given the year or exact model of the donor GS1000, but the closest GS1000 model to the GS850G is the 1980-81 GS1000G.

Unfortunately for you, if you check a microfiche, these intake boots are a different part number. Therefore, the GS1000 boots will not fit your GS850. (The GS1100G boots are also different, as are the GS1000 chain drive boots). The internal diameter and the bore spacing is slightly different on the cylinder head side.
