1986 honda gl 1200 aspencade

Postby slingshotal » Tue Jul 10, 2012 1:41 pm



hello all, can anyone help me.
I have a 1986 honda gl 1200 aspencade.
I just installed a new fuel pump. but I can't seem to keep the engine running .
it starts up when I spray starting fluid in the air cleaners.
but it still seems to be starving for gas . I have removed all the carb caps and fixed all the sliders. 3 out of 4 were stuck .
I pulled off 1 of the fuel lines going to the carpet is pumping gas fine .
I also remove the gas cap thinking I might be building up a vacuum.
it also has 4 new spark plugs .
does anybody have any thoughts? I appreciate the help.
thanks
Allan

Well,you got spark and compression,so the only thing left is fuel.
I guess I'm stating the obvious.....sorry.

You mentioned that the slides were stuck...Did you also go into the carbs and clean the fuel passages,jets and check the floats.?

If you believe it's fuel starved and there is plenty of fuel going to the carbs,you can verify that it's actually getting into the carbs by opening the drain plug one at a time.

I'm gonna guess here,but each carb should hold about a shot glass full of fuel.
Now if there is plenty of fuel in each carb and it's still fuel starved,the jets may be plugged up,and a good cleaning is in order.

Also when I "do" slides,before I put the carbs back on the bike,I'll attach a shop vac to each inlet pipe and operate the throttle and verify the slides work smooth.

after spending the day taking the carbs apart I now have them soaking in seafoam yes apparently all the jets and needles work locker very bad .
I also have a 1982 v 45 magna, I believe is experiencing the same situation .

I hope your spell checker goofed up..." jets and needles work locker very bad"....
I guess that means the jets are plugged up.
Let them soak and remove them to clear the jets out.
Lots of rebuild info here and on the net.
I also have a few things I did to mine to alleviate a flat spot in the 1500-2500 rpm range.

Did you try to start it with choke fully on? One area wich can easily cause problems with gummed gasoline, are the idle mixture screws. Those screw's tips are responsible for running condition at idle.They have very tiny passages into the throat of the carbs. Choke should bypass that.

thank you for all the advice gentleman. if you're soaking all the parts in seafoam all day a successful assembly has it running very well.
it was definitely all gummed up with old gasoline and shellac bad on the inside.
I'm happy to say she is now purring like a kitten.

Slingshotal.....question: Does your bike sit for long periods of time? How often do you, or have you, started it?
Reason I am asking, I wonder how often it needs to be started or driven, to keep carbs clean. Or do they get gummed up over time regardless? Mine is ridden about twice a week, plus/minus, and I am not sure if I need a carb cleaning on mine.

Zamboni, my 1986 gl 1200 has been sitting idle for 3 years .
however I have a 1982 v 45 magna which has been sitting for 3 months and the same thing happened. after all the research in the past couple of days I have found out that if it is run regularly you should never have a problem.
adding some seafoam gasoline additive for preventative maintenance certainly helps a lot. :D
