GL 1100 SLUGGISH

Postby fynespirits » Wed Sep 02, 2015 11:38 am



Hi all , new to goldwings but have bought a Gl 1100 aspencade from a guy who is no longer able to
handle it and has bought a smaller bike .
he only did a few miles a year on it and it seems to be underpowered and bogs down in the midrange of the revs
in every gear .
being new , but a car mechanic by trade I would appreciate if some of you could point me in some likely directions
to get this wing back to full power please .
as of yet I have not done anything to it as I will be collecting the bike in 2 weeks time once I have fitted my ground anchor
for security reasons .
Cheers

My 83 had difficulty above 3k rpm...Before I went too deep,I stuck an angled mirror into the bottom of the plenum box...Using a flashlight to be able to see each slide,I rapped the throttle and watched each slide go up and down the same amount...Except one of them...That little goober was stuck closed....
I pulled the whole carb mass and meticulously cleaned them...including testing the slide action with a shop vac...A pre-sync on the bench..final sync on the bike and it was amazing how quick it would reach red line...

Cheers for the quick reply !
never having striped the carbs on a wing before ! Is there anything to be overly careful of ?
any notorious problems that cause headaches if not watched or prepared for ?

It's tedious work...It takes me more than half a day to get a set pulled,cleaned,adjusted and put back.
The biggest thing is keeping everything clean and each carb with its own parts...eg..don't mix up the caps,slides,floats,etc between carb bodies...I usually do them one at a time...The only time I had to purchase parts was to replace the bowl gasket or fuel needle valve.....
Most every one just took a bunch of cleaning and polishing the slides...
Personally with yours,if it idles well and seems to run fair,I'd only expect sticking slides...You may not even need to open the bowls...Do check this first before you rip the carbs off the bike...
It's possible there's another problem causing this...Looking at the slide action is the easiest and cheapest thing to do first....
If they are OK...then you can start the process...Fuel quality,Compression test,spark plugs and wires,battery volts for the spark,fuel filter,air filter,valve adjustments,checking the timing belt marks,vacuum advance canister and timing advance operation...the list goes on and on..

I just have the habit of doing the easy and cheap stuff first...
