I'm already late to leave to see my girlfriend and my bike doesn't want to go anywhere. I got home from over 3000 miles and some bike trouble on the road (died due to not charging well in a long traffic jam), and I started doing a little work on my bike and now she won't run.
Here's what I did:
1. Fixed a short on the rear running light, shoudn't have affected anything
2. Checked condition of spark plugs. They looked pretty good to me (photo below) and I checked torque twice.
3. Changed both pilot jets back to stock, from +1
4. Changed rear main jet to stock, from +1
(not listening to any advice on jets in the future. I don't think I needed to rejet in the first place
Then it didn't run worth a @*#$. Took the carbs apart, cleaned the float needles. Cleaned everything else in them. Everything looked fine to begin with, but just in case, right? I don't see gas coming through the petcock. No vaccum leaks on the boots or starboard vac port on the carbs.
Still doesn't run worth a #*&$. Cleaned the carbs a second time. Still misfiring badly. It can't be too lean to run just from changing one jet size, especially since choking (enriching on these bikes, of course) doesn't help.
It seems to be misfiring badly and running mainly on one cylinder. If I had to guess, I'd say the front is misfiring, but it's hard to tell. What do I do, pull the carbs a 3rd time just to go back to +1 jet sizes? If that was the problem, it should at least idle great with the choke (enricher) on partially, right?
All of the spark plugs are turning black now. Here's what they looked like before:
