Re: 82 gl1100i CARB SYNC

Two thoughts... the adjuster screw on mine was stripped. I could turn it but it didn't actually move the mechanism.... secondly, are the #2 & #4 butterflies actually at rest against the carb throat? They might be so far closed that the adjuster has to go a long way to get them to start moving at all...

Re: LOCKED UP! HELP!

Possible suspect is hydro locked. Usually on the left side if the bike was on the side stand. Did you try the starter motor... (a mere question only... hope you did NOT try starter before confirming the motor would rotate). Were all the tests mentioned done while trying the rear wheel method? The "c...

Re: rear drive shaft on gl1100, by rear tire one bolt is frozen

Yes, you can use moderate heat. There is an O-ring inside that you might have to replace. A 1/4" ratchet is a bit small. 3/8" with 6-point socket is best. PB Blaster is a good penetrant. I think a nut cracker would be difficult since there is no room around those nuts. It's barely enough room for th...

Re: Carb problem gl1100.

Just for "education purposes", bend those float tangs to provide more shut-off force on the needles. If it stops the flooding, then you know the new needles will solve the problem when they arrive. I replaced 2 of mine when I could not free the little plungers. The replacements were aftermarket and ...

Re: Carb problem gl1100.

I know you have checked many times... but it seems the float valves are still not shutting the fuel off. They should handle 4 foot of "head pressure" from the supply tank. While they are on the floor, take the round covers off and lift the pistons out. If you see fuel coming up the main jets, you ca...

Re: Carb problem gl1100.

Yes... Adjust it for max idle speed. But, to be sure it has a proper effect the idle and low jet passages must be clear, and overall idle setting below 1000 rpm. If it is already idling too fast the idle screw no longer has much influence. Also if that carb is flooding due to float needle problems, ...

Just to clarify the idle screw function. These are fuel screws, not air screws. CCW = more fuel, not more air.

Re: Carb problem gl1100.

If you conclude that #4 is flooding, try to confirm if its flooding even with the engine off (assuming petcock = on and fuel tank is full enough to gravity feed fuel thru the pump). If fuel is flooding under that condition it is probably due to high float bowl level. It would rise up thru both the h...

I don't know about UK equivalents to SeaFoam. It is a solvent that you add to gas. Some believe it is a "miracle in a can", while others say it solves some problems but it's NOT a miracle. Sometimes you just have to pull the carbs (again... Ugh) and mechanically clear the passages. I had success cle...

The center stand pivots on a cross tube under the bike. The cross tube goes thru the center of the centerstand,s upper tube. Lubricate these concentric tubes upon reassembly. The cross tube is held in the bike's frame by a pinch bolt on each side. Perhaps the cross tube was not part of your replacem...

Re: Cant get my gl1100 to stay at idle

#1and #2 fire together off as single coil. Same with #3 and #4. Are plugs wet or dry after an attempt? Multiple twists on the throttle should pump raw gas into the throats. Should get same result as raw gas in the plenum. If not, figure out what's preventing that result. Low jets won't go "too far" ...

Just guessing now... Seems a mystery.
Did you put the floats in upside down. How do you know the fuel pump is delivering gas? Petcock turned on? Fuel lines or filter clogged?

Re: Cant get my gl1100 to stay at idle

Back to basics. Can you keep it running above 2500 with throttle after starting with raw gas? That checks main jets ok. Does choke help? Look down plenum with a mirror to check accel pump. That verifies gas in bowl #3. Check bowl drains to see if all have gas. What settings on idle screws?

I agree, let's not start a "which oil" argument. But here's my $0.02 worth anyway. Oil and rubber don't get along. But automotive type O-rings aren't rubber.

Another guess... Are you sure the idle jet is in fact clear.. they are not easy to clean in place (although they did clear on my recent carb rebuild). If they didn't clear, then you probably had to crank up the idle setscrew way past normal to get it to idle off the main jets. One test might be to s...

Just guessing here. How did you sync the carbs? Assume you did it on the bench since the bike doesn't idle well. Have you messed with the sync adjusters since then?

Re: '82 vs '83 speedo threads

The 85 mph speedos were born in the era of the '70s oil crisis, pollution controls, and 55 mph national speed limits. Mostly summarized as government overkill, over regulation, and ignorance. Cars of the era also had 85 mph speedos.

Re: Timing belt replacement

The engine stays in the bike. It's a good idea to remove the radiator, to save your knuckles. I never did a '83. Crash Bars are different on each specific model. Just take a look under there.... does the crash bar interfere with removal of the front belt covers... maybe they do on an '83 ??
