Hi all,
Finished my TCI to points mod with quite possibly the help of every stinking member on this site.
Upon testing the timing, I have uncovered my next problem to which I don't know where to start. When I hook my timing light up to my left spark plug wire, my timing is in between my F mark. When I hook my timing light up to my right spark plug wire, my timing mark is just outside the right F mark mark (see my illustration picture attached).
Now...XSLeo had a great explanation on how both plugs are fired at the same time, thus both spark plug wires should measure timing the same.
So, here is what I've done to ensure that this is not user error...or rather KNOWN user error.
- Timed to the right side spark with timing light (NOTE, my timing light does not care on it's orientation to the plug wire)
- After getting the bike to start, I get it to where I can run without the choke
- I synched the carbs with manometer
- As signature says, I'm running uni-foam filters, 45 pilot, 137.5 mains about 2.5 turns keeps the bike running
- Exhaust is a 2-1 and shown in the other picture attached
- The spark plugs have black carbon after about 1/2 hour of running (total, not all at once), they were new as of last night
I would love some help determining where to start to find the issue.
- Stuck choke?
- Gummed up carb jets somewhere (cleaned them twice and they appear ok)?
Feeling overwhelmed...breathe, breathe...
