The round slide (VM series Mikunis) ID is often difficult to find and to see as it is small and engraved into metal. It is on the flange of the outside carb as shown in this picture. The number can be four or five numbers and letters but most Suzuki Mikuni VM carbs seem to be five numbers in the 4nnnnn series. The number in the manual may be 41234 but it will be stamped on as:

4 1 2
3 4

and will be located here:

Just checked the number on the 1000S and it reads

P9
61

Nothing else in that spot.

I have an '82 850GZ. I have the factory Suzuki manual and I will post the carb specs. for my bike tomorrow. Have you guys decided if there will be a dedicated page on thegsresources.com for this info.?

Mike
 
not really this topic has been lurking for a long time i guess one of us needs to get off our ass and put this info in a excel or word document then pdf it so it can move over to the garage. i think we now have all the models covered.

Ryan, do you have the 82-83 1100 info? if not I can try to post it tonight, I have the factory service manuel that covers the G, GL, GK for those years.
 
ok guys my brain hurts, i am trying to get all these carbs we have sorted out and in some sort of standard format

i think w have most of the bikes listed but we still need a few more, some of the ones i know for sure are the 82 -83 1100 g series bikes
as well as the gs 300 carb specs, the gs 125? carb specs the gs 250 carb specs? the 77-78 gs 400 carb specs, the 80-82 gs 400 specs, and the 83 specs. those are the few i can think of right now. as well as some verification of the info that i have compiled and filling in of some missing blanks.

it is going to take me a little time to be able to sort all this stuff out and put it in some sort of standard format. i have so far got stuff listed up to the gs 1000's but nothing is in a standard format yet.

after we get these oem carb setting set maybe we can start loging some KNOWN GOOD settings for bikes with modified carbs like people useing gsxr carbs with what motor and what mods. maybe in the next cople months i can list my settings for the 29mm smoothies i have on my 1000 i am working on.

if any one wants to add info please follow the two types of formats
