Carb OEM specs as per factory manuals

[jonr]

Ryan,

I PM'd you the specs from my 76-79 GS750 factory service manual. This manual is not near as thorough as the 80's models though. I hope the info is enough.

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.

[first timer]

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

1986 GS450L carb specs

Does anyone have carb specs for a 1986 GS450L?

[Anonymous]

I found this in my service manual.
It is for GS750 1976-1979 ,GS550 1977 - 1982



Check the Engine no. ,not frame no. Look for the differences on the same model!!!

I hope it will help

[Anonymous]

Anybody have the pilot screw settings for an '83 GS550L? I was looking at the 550E post above, but my pilot screws were removed by a PO and I'd like to double check what he scribbled in the Haynes manual.

Thank!

[TheBigRed]

yeah man post your 650 info please try to use the format i have used

thanks
-ryan

Ryan,

Was looking through last night and realized I never did post the 650E information.

Here it is:




(as you can see it is different from the 650G(L) models posted earlier.
