Yep, sounds like your running rich on the left. Adjust your carbs and you should be fine.

howdy,

my ambo goes through headlamps really quick. i'm on my third one in less
than 1000mi. i'm wondering about possible causes?

the two i've installed were sylvania 55/65watt standard halogen round low/hi
car lamps.
my switch is an aftermarket, pseudo modern (probably japanese) horn/light
switch.

i lose my high beam first, then not too long after, the low beam goes. i
wonder if this is an electrical short problem (no fuses blown) or a power
management problem related to the "increased wattage" of the lamp relative
to the original. the battery is fine, and the charging system works fine,
and the bike starts with no problem.

it's also possible that hitting potholes has bounced the filament and blown
the bulb. has anyone else had these problems and is there any way to deal
with it (i live in jersey, so not hitting potholes isn't an option :-)))

next question:

disclaimer: i am very new to wrenching on motorcycles. i have never done
carb or motor work of any kind. so please be gentle with my inexperience.
this is part of the reason i bought the grumpy old bugger. i really want to
learn how to take care of them myself.

symptom: left cylinder appears to be firing "less" than the right one.
when i put my hands behind the pipes at idle, i feel approximately 4 solid
puffs on the right to 2-3 not-so-solid ones on the left. also, the left
pipe shows considerably more carbon buildup at the end than the right.
also, visually, the exhaust on the left appears to have more fuel vapor. i
do not have a crossover. motor doesn't miss. generally runs fine. so...
am i looking at a possible carb-sync or richness problem with the left
cylinder? plugs? compression problem?

many thanks for any help.
