Air jet confusion
Last night I started reassembling my 1000G carbs, and I ran into a bit of a quandary. According to my copy of the factory service manual, the main air jets should be "1.7". The parts in the carbs that came with the bike (and identified as the air jet in the carb cleanup series) say "180". All the other jets, needles, etc. match the spec. I don't know if it matters, but the air box doesn't have a stock-style air filter, it has that mesh-looking stuff that the K&N pods look to be made of. Can you all comment on this, please? I had a poke around the web, but wasn't able to find another reference to verify the "1.7" or somehow reconcile it to "180".Dogma

The 1.7 is correct for the MAIN air jet. It is the one in the 4 o'clock position in the carb intake.
The 180 is correct for the PILOT air jet. It is the one in the 8 o'clock position in the carb intake.
Two separate jets.

Thanks guys.
Again I was confused by nomenclature in the carb rebuild series. It only says "air jet". The FSM only mentions the main air jet, so I assumed they were the same. Curious that the FSM makes no mention of the pilot air jet in the tables.Dogma

Say, what's a good resource for checking on these things? I don't doubt you when you say that 180 is the correct pilot air jet for the GS1000, but how do I find that data for myself next time the FSM comes up short?Dogma

Apparently, I didn't search very thoroughly. That thread did cross my mind at one point. It must have crossed all the way through.Did you check here http://www.thegsresources.com/_forum...ad.php?t=73723
The data I find there (post #28 and 136) says 160 on the pilot air jet, not 180. Post #136 says it needs to be cross-checked, so it may not be authoritative. Steve, May I ask where you got your info?Last edited by Dogma; 02-11-2010, 03:49 PM.Dogma

Chances are they weren't changed from stock but who knows.
I can't seem to find the info in any microfiche. It says "discontinued" and I know they can still be bought.

Thanks for asking.
I got it from post #108 in the carb "sticky" at the top of this forum.
Okay, finally got tired of replying to PM's about the spreadsheet. Not that there were that many, I just finally got around to posting the file on the 'net...
hope this helps, although I haven't updated it since I first posted about it.
find it here: http://members.shaw.ca/johnwightman/images/SuzCarb.xls
let me know if the link doesn't work.sigpic
