'83 GL1100 standard, new owner and have a few questions I couldn't find answers to.

Postby chrisz » Sun Jun 21, 2015 12:31 pm



Hi,

Recently picked up a new to me GL1100 standard with about 50K miles on her. I drove it home about 100 miles and have a few questions I'm hoping the good folks here can help out with.

My bike ran well, smooth engine however did seem low on torque. On the highway it seemed ok at 70mph, but didn't encourage faster speeds. It does have a standard front fairing, but expected more umph. (I know this is 32 year old bike, but still..) Is this mormal?

Clutchless upshifts are ok with this bike? I've tried it, seemed fine. Any concerns from the collective?

Bike came with air suspension, but I didn't see the compressor inside the false tank, so how does one adjust the pressures on the front/rear (it was quite soft I found when taking it home)? I have the owner's manual, but it only mentions the pressures to use, not how to actually add/remove air. Do I use a regular shop compressor with a tire gage?

The brakes are linked, so the rear brake pedal worked fine, however the front brake (one caliper/rotor working) was very weak. The bike has passed safety inspection and the brake fluid was flushed within the past year (have service records). Is there anything that can be done to greatly improve the front stopping distance. I use both hand/foot brakes, but occasionally like to use only the front to reduce speed a bit.

Thanks,
Chris...

I have a 83 GL1100 standard have owned it since 93 it has 58K miles on it, it has 83 hp and it weighs over 600 lbs. not exactly a sports bike, the 83 has different gearing, it runs 500 rpm slower that the 80 thru 82 1100's at speed, but it will run 70+ all day long with no problems that what it was made for.
If you don't care about replacing the clutch or the trans keep shifting that way, this is OLD technology, modern for it's time but really, BMW just came out with clutch less shifting in 2014. This bike does not have an on board air compressor and you do not want to use a shop compressor on it, it will blow the seals out to much pressure you need to get a hand pump, you add air on the front on the left fork top left, and on the rear under the right side cover as shown in the pictures on page 9 in your manual to help tighten the front set the TRAC up to 4 and or go to Progressive suspension springs up front that will help.
As far as the brakes go if you have changed the fluid and there is no air in the lines and you have good brake pads on the bike and the rotors are not warped, you could put steel braded lines on the bike this would help, I have braded lines on my bike and it stops well, not like my 1200cc 505lb BMW with ABS and all but it does OK for a 32 year old touring bike. Have a good time with that bike they are great fun to ride leisurely.

Thanks JG, I appreciate the advice.

Regarding the shock air pressure, I understand from your reply that I can use a bicycle hand pump to pressurize the front/rear shocks. Will try that along with the TRAC setting, (not quite sure how the TRAC is supposed to work).

I did ride a BMW for over 9 years (R1150RT) and did quite often upshift without the clutch, it performed similarly to the GL, not very satisfying. You are correct, this bike is a relaxed touring rig and I will need to respect this.

I saw that the seat on the GL can be adjusted front to back about a couple of inches, is there any way to adjust it up/down? I would like a bit more leg room.

Thank you,

NEVER use an air compressor for the air shocks.
There is no adjustment for up and down on the seat.
The 2 bolts that attach the seat in the back have been removed from my bike for 2-3 years now.
The 2 bolts that hold the tank shelter in front have been removed for 9-10 years now.
To see what happens when you use an air compressor on shocks watch the first segment of this video and you will see how they pop out with just a hit on the air compressor.

Change your brake lines from the 30+ year rubber, that now expands when you put on the brakes, to stainless steel lines.

NEVER use a compressor to add air to the shocks.
There is no way for up and down on the seat.
The 2-3 inches forward and back--I removed the two bolts in the back of the seat and just move to where I am comfortable. The bolts have been out for 2-3 yrs now.
The 2 bolts that hold the shelter tank on in front have also been discarded for 9-10 years now.
Leg room-- Been a problem for everyone since the bike came out.

Regarding: "The 2 bolts that hold the shelter tank on in front have also been discarded for 9-10 years now."

What is a Shelter Tank and why were the bolts removed?

Thanks,

The gl1100 standard should pull hard through "all" the gears. Well past 100mph. 1/4 mile stats is something like 107 mph and 12.? secs. Even though 5th gear on the 83 is considered OD your bike, if running properly, will impress for what it is. Sounds like you got some tuning to do. ;)

shelter tank(false gas tank) is the big thing between both your knees. Where the gas goes in. 2 bolts are a pia to get to. They are located in front down by the front forks.

Have you sync'd your carbs?
Adjusted your valves?

This may help your speed.

Tinker with it and you will enjoy riding it for many years to come.

Thanks guys.

Yes I was expecting a bit more umph from the bike, and from what I just heard (read) it should be quicker than it is. The previous owners have documented all work/maintenance but the last valve adjustment and carb sync was done about 10 years ago! It seems to run ok and idles fine, no hickups. But yes, going over the engine and drivetrain will be necessary. The timing belt tension was adjusted by the dealer (along with oil/filter change) while the safety cert was being done prior to bike's sale by previous owner. I didn't know the belts needed tension adjustments (they are auto adjusted I believe).

I'm sure I'm going to have many more questions in the months to come.

Thanks,

Something is really out of whack, it should just be getting started at 70 mph. Check and make sure it's not just firing on 2 cylinders or something. While no powerhouse, my old 82 will run out of steam at about a buck twenty if you got the room and guts.
