Mikuni Main Jets
I am rebuilding a set of 1993 SL750 carbs. My clymer manual says that there are supposed to be o-rings on the main jets, but there were'nt any on them when I disassembled them. I did a search on Green Hulk but didn't find anything. Are they necessary? It does'nt say anything about them in the 1992-1998 Factory manual either. Please advise. Thank you

The clymer manual may be wrong. I think it's mis-guided a fellow a time or 2 before. There are no o-rings on the jets. There is a seal for the kidney shaped valve block. Is that what they are describing? It doesn't sound like it.

Correct, are you sure they don't mean the adjustment needles?
Those have O rings.
Also the needle/seat has an O ring seal.

No, I know what hi and low speed needles are. Both are externally adjustable. The main jet is underneath the check valve body, the kidney shaped block. I believe starflight is correct. Here is the page from the Clymer Polaris shop manual 1992-1995. Step 12.

Here is a better close up of step 12.

Thanks starflight. No, I hadn't seen that mikuni manual. Looks like a lot of good information. I saved it so, now all I have to do is look for it on my computer when I need it. If I can remember anyway. Old age, there's no future in it. LOL
Thanks again, starflight, and have a good weekend
