I rejetted my carbs because the plugs were reading rich. I have an '80 xs650 (SG, i believe) stock CDN needles, uni filters, 2-1 exhaust, jets are: pilot= 45, needle is CDN in middle slot (stock) and main is 132.5.
I switched out the mains to 135 and moved the clip up one notch on the needle (leaning it out). Plugs looked a little better but the bike ran terrible. mid range was stumbling and it was hard to keep it running.
Also, the left pod (kickstand side) was leaking fuel. I returned the main and the clip to the needle position and it stopped leaking fuel.
Does it make more sense that the bowl had a piece of something lodged in it from the disassembly or would the new jetting cause the fuel leak?
The bike is running better with the needle back and the main back to stock, would the mixture screws be enough to lean the bike enough for the plugs to read proper?
With all that being said, if it was stumbling in the midrange but the plugs were reading better, would it stand to reason that I could lower the needle (raise the clip) to eliminate the rich plugs and bump the pilot to 47.5 to eliminate the low RPM stumble and bump the main as well to compensate for the leaned out needle?
Can somebody explain the fuel leaking from the pod?
Thanks again
