I'll start to get this bumped.
1) Yes, you can simply plug the vacuum tube on the #2 intake.
2) I'll let someone else who has recently jetted chime in here.
3) Little confused on this one. I think you need to remove the needle jet that sits in the vacuum slide and shim that so it sits physically higher in the slide. No extra washers are needed on the actual main jet and holder.

Hi Mr. nwcrowder,

Generally, with pods and pipes, you need to go up a couple of sizes on all your jets. Use the "plug chop" method to fine tune the carburetor configuration. It's not an exact science. Search for jetting posts by KEITH KRAUSE. There are also informational links on my website. Let me roll out the welcome mat for you.

basscliff thanks for the welcome.could someone post a link or pic of the washer that needs to be replaced or were it goes to shim the needle to richen up the pilot circuit. i guess i am a dummy because ther was no nylon washer on the needle jet.also specs on float height? go with the manual? i was going to start with 125 on the main jet 2.5 turns on the mixture screws and leave the pilot at 40.any advice and help is greatly appreciated.

The shimming is acomplished by completely removeing the slides from the carb bodies

Inside the top odf the slide is a snap ring. Remove the snap ring and the needle will come out. On top of the needle is a nylon washer about 3-4mm thick.

Replace the nylon washer with smaller thickness washers of your choice. this creates a richer mixture or allows more fuel to flow.

Reassemble the slides and install back into carb bodies making sure to align the tab of the rubber diaphram on the top of the carb body.

Put the caps back on the carbs and start her up.

Note: This isn't a sub for jetting. Just a way to make the bike run a little richer and take advantage of the full power band. This procudure can be acomplished with the carbs on the bike, no need to remove them.
