Mystery Carbs

Yeah. Another job I don't want to do and told him that. I believe this seal will work. https://www.ebay.com/itm/317124386392

I just did it and it was easy. It did lead to me messing with pickup coil wires which was more time consuming.

Did you use this seal? https://www.ebay.com/itm/317124386392

Might want to give this a read. Everything you need to know about that seal and replacing it. oil on the good foot - XS11.club Forums

Only use a Viton seal. If the seal surface it pitted (it probably is!) you will need a surface sleeve.

The Dynojet kit says IM screw 4 turns out. Anyone install one and know where you ended up. 4 turns feels like it's not even touching the spring.

What jetting did you finalize on or have you yet? 4 turns seems excessive. Will be rich unless you went down in size on the pilot jets. I have never fooled with a Dynojet kit on these bikes Never really saw a need for it if the proper guidelines outlined in the carb section of our maintenance tips. Not saying those kits don't have their applications, but from what I have read they are more geared to racing. Most folks end up with them, and this is only my opinion, because they think that is going to be a solution for other things they don't understand about CV carbs. Why I asked early on in this thread if you had the original parts available to you. I know, you are just dealing with what you have and trying to help a friend. I only point these things out for other reading along so they can decide for themselves whether those kits are worth the bother. I am sure you already know that most times it is recommended to lightly seat the screws and then start at about 2.5 turns out. Synchronize the carbs then fine tune from there. If getting them tuned from there is not possible then it is time to think about different size jets depending on what you discover in the fine tuning stage.

Keeping in mind that everything else is ok. Meaning no shaft seal or manifold leaks etc...

Were the slides and main jet needles altered and installed from the kit? I went out and looked up the instructions for the kit and just like you stated it says to start at 4 turns out. Still seems like a lot but I guess at this point you don't have anything to lose by trying that as a starting point.

I am posting the dynojet instructions E4101-Installation-Guide.pdf. I am assuming at this point that you are dealing with the Stage 3 kit? Even the Stage 1 kit says 4 turns out from lightly seated.

I'll start there and see where it stumbles when I screw in.
