1984 Honda CB700SC
 
Bike has been doing pretty good (minus the issue with the fork seals).  Put 
maybe about 250 miles on her after the rebuild.
 
Anyway, I ran the tank down pretty low (tank is clean), however it acted 
funny the next day, like a lean throttle hang.  Picked up some gas and 
seemed a little better but I knew she wasn't 100%, went for a ride anyway 
about 30 miles then it sat for about 5 hours, came out and went for another 
ride and noticed I could smell unburned fuel in the exhaust.   15 miles 
from home coming up to a traffic light she pretty much shut off, went to 
crank her over but it was almost like a hydro lock, would do half a turn 
then stop dead.  Pushed the bike off to the side of the road and called the 
wife to head down with some jumper cables.  
 
I tired a few more times to start it while waiting for my wife and the same 
thing would happen (like a hydro lock), I waited about 20 mins for the wife 
to show up, figured what the hell, hooked the cables up and the bike 
started right up and drove it home.  Upon getting home I decided to do some 
checking.  First thing is the battery I picked up is a super cheap-o 14L-A1 
for 35 bucks, it seems to lose power quick if the bike doesn't catch right 
away (which is normally does, just a tap of the starter button) ordered a 
AGM battery and a special charger for it.  Also noticed the choke wasn't 
fully closing on the carburetor, I correct that issue.  
 
So even with the new battery, and the choke fixed, I took it for a quick 
ride and she still just didn't feel right to me. After 10 mins I went back 
to the house and decided to check the sync, and it wasn't bad, just a 
little off but not bad.  Shut it off to disconnect the gauge, went to 
restart and same thing, like a hydro lock but starter was still able 
to pull threw a few rotations (that AGM battery is nice), it sounded like 
it was out of time and I did notice the RPM gauge jump quite a bit like up 
to 6k even though the engine wasn't running. 
 
I did take the carbs off and nothing really to say over fueling is evident, 
no fuel in air box and the carburetor bowls are spotless (was thinking 
there would be junk in there if it picked up something from the tank).
 
Ok so after all this I'm starting to wonder, do I have a CDI failing when 
hot?
