Greetings and Salutations!!

Hi Mr. devon boxer,

Most of us here are not fans of "professionally" cleaned carbs. We're a real DIY crowd because most bike shops don't care about these old bikes like we do. You'll find most of what you need for regular maintenance on the GSR homepage and my little website.

You'll find stock carb jetting specs on my little website. But with your modifications you will have to experiment by reading the spark plugs after some "plug chops". Those procedures are also on my website.

A "114" main jet? Is that a typo or a DJ jet number? The Mikuni jets use a different numbering system than Dynojet. You'll find Mr. salty_monk's conversion spreadsheet on my website or you can Google a conversion chart, they're all over the internet.

Normally, with pipes and pods, you will have to go up a few sizes (4 to 6) on the main jets and the richen up the midrange by raising the needles a notch or two. It sounds like you have lowered the needle a notch.

Anyway, here are some links that I hope will give you some pertinent information. It's your "mega-welcome". :)

If you are here you probably have a 30 year old motorcycle that needs about 20 years worth of maintenance. You'll find all kinds of helpful tips, procedures, manuals, diagrams, "how-to" guides, etc, in the links below. Let's get started.

Let me dump a TON of information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.
