losing power on acceleration

[AlaskaWing]

After I exited the highway onto surface streets my wing developed an issue. When I get on the gas it sounds like it is missing or flooding, but still seems to keep running. It sounds like it bogs down when I try to accelerate, whether I am at 40 or starting at a light.

I thought maybe I had a loose plug or something, but all the wires are tight. (I pulled each of the wires off of the plugs last night trying to identify my clicking sound.)

I drove it about 3 miles to a friends, let it sit for a couple of hours. Started it (fired right up), then rode it home. It continued to do the same thing until a couple of blocks before I got home, then it cleared up.

????

What is it?

(We should assign a point system for correct answers!!!)

Gremlins? :smilie_happy:

~O~

 

[Steve83]

Maybe a little water in the gas???

 

[AlaskaWing]

Gas comes from COSTCO.

I could try changing the fuel filter I suppose.

Where is it??

Fuel filter is at rear of carbs below the seat

Definitely sounds like a fuel problem. Mine did that once a long time ago. Just the one time, and I figured I had gotten some kind of crap in the carbs that cleared itself after a few miles.
Could also be an ignition issue, such as a loose connection, so ya might want to check the coil connections, and the connector for the pulse generator back there by the stator connection. Hope it was just doo-doo in the carbs that flushed itself. :beg:

I had a similar problem that turned out to be a vacuum leak at my intake manifolds. The o-rings were leaking and whenever I throttled up it would hesitate (and sometimes pop).

 

[AlaskaWing]

I wonder if this fuel filter could have been the problem.

I wonder how long it takes for a fuel filter to crystallize.

I bet they are a lot easier to change if I can figure out how to take the seat off.

 

[toytender01]

Removing the seat won't help.

:shock: No wonder it wouldn't run, it's a wonder it got over an idle. That's the worst looking fuel filter I ever did see. :smilie_happy: :smilie_happy:

 

[AlaskaWing]

The fuel line was showing some age cracks too so I replaced those as well.

I just hope that solved the issue.

 

[slabghost]

Can't say if it solves the problem but it has to stand a much better chance now.

Jurassic Filter?

You need to start running 8oz. of ATF in every tank...at least for a while.

~O~

:good: Agreed.

 

[AlaskaWing]

OK. ATF is in the fuel.

When I look down into the gas tank I see little specks of rust on the metal at the bottom. Those wont hurt anything right? It looked like they were not free floating.

 

[slabghost]

Just watch your filters.

 

[backlander]

How's it running since you changed the filter ?

 

[AlaskaWing]

Seems fine, but it had cleared up before I actually dug into the filter.

It ran rough for a few miles, cleared up for a few blocks, ran rough for a few blocks, then cleared up.

I can only assume that I must have passed a little piece of that fuel filter through the system and it is gone now.

The clicking sound is still bugging me. But I think it is a hole in one of the seals in the exhaust system.

Since I switched to a thinner oil, it does not slip out of gear anymore under heavy acceleration at high speed.

I am happy.

Been considering an Iron Butt. Anchorage, Fairbanks, Tok, Valdez, Anchorage. 1000 miles. (my wife doesn't want to follow me in the car though.)
