10 Points for Best Answer! Why is my motorcycle stalling?

Question

I have a honda shadow, 1988 VT1100C. It hadn't run in a while, but the carbs are now clean, and I jetted the bike and everything was running ok. Not perfect, but ok.

Today I finally got the new fuel filter in, the old one was awful clogged up with rust, but it was backordered. And now, with a nice new clean filter in, I stall if I close the choke. Meaning I put it in the position you would to start the engine cold, and shoot that extra gas in the carb. Why would more gas stall me? Did I do something wrong when I installed the filter? Or is it just that the jetting needed to be done after a filter change, and not before.

Answer 1

Drain your gas out, remove the fuel petcock and clean that.  Its hooked up to your fuel line.  Also check your spark plug its like a meter as to how good your engine was running.

Answer 2

your jets may be too large, also the carbs may need to be sicronized ,its like the timing on a car

Answer 3

adjust the Idle s***w !

Answer 4

Adjust your jet screws. Your old filter was restricting air, now you need more fuel. Back the screws out a few turns and try it.

Answer 5

The inside of the tank has gone rusty. You need to remove the tank and clean it out. Put a little bit of fuel in it and a handful of small ball bearings (or nuts) in it, and shake the h**l out of it. Then flush it to make sure it is clean. You also need to clean the rust out of the carburetors (removing the bowls will show it) . Reassemble It with a NEW fuel filter. I had to do it to a friend's 1980 Kawasaki last week, It runs good now.

Answer 6

if your filter was REALLY bad, then you might need re-jetted...

this is why i don't deal with carburetors anymore..EFI is so much easier to adjust...
