Old Rider with "New" GL1100I

Postby doctorpaul » Mon Nov 19, 2012 8:01 am



Greetings! I found this 1980 GL1100I for sale recently with 1132 miles put on the odo between 1980 and 1991 when the original owner parked it in his garage. There it sat for over 21 years completely covered and out of the weather until I rolled it up on my trailer a couple of weeks ago. Joined this forum to learn a bit about these older bikes. Drained tank of what was left of 21 year-old fuel and it cleaned up pretty good. Some rust but it cleaned up really well with a few vinegar rinses. Replaced old fuel lines and put a pair of filters in-line. Fresh oil and filter. Drained, flushed and refilled cooling system. Overhauled both master cylinders with new OEM parts and serviced all 3 calipers. Original tires are in amazingly good condition without any brittleness or cracking and they hold air fine. Wouldn't go far or very fast on them but they are in incredible condition for being 32 years old! With fresh fuel and half a can of Seafoam in the tank, she started right up but wouldn't idle well. Despite running around a half gallon of fuel through, couldn't get the idle circuits to open up. Removed, disassembled, thoroughly cleaned (Chem-Tool plus ultrasonic) each carb. All gaskets, seals, diaphragms, floats and valves, and jets were good. After reassembly, she fired up and idled like new. After a 60 mile shake-down ride yesterday, I'm very pleased. Next is new tires plus the 600 mile valve check the original owner never got around to ... ! Paul

Good for you,thats a very nice find.even though there are so few miles on it, you really should replace the timing belts before starting it again. They have been sitting in the same position for years and could be weakened, I would hate to hear that you destroyed your engine for the sake of the cost of new belts and the time to install them. NAPA sells them for much less than Honda. 8-)
Ride safe, Todd

30+ motorcycles over the past 40 years but this is the first bike I've owned with belt driven cam shafts. I had wondered about replacing them due to age alone. Do you have the NAPA part numbers? Many thanks for the good advice, RoadRogue! Paul

Thanks! I'll get right on finding a set; sure hate the thought of one breaking! I'm planning on having JDA build a set of brake lines as well. They made a set for a GL500 Silverwing Interstate I had a few years back and do good work at a reasonable price. These brakes are OK but the fronts are a bit soft due to 32 year-old rubber.

The '80I I have also has the ss brake lines on it and it makes a difference. That bike is a timeless classic and should be great to ride and enjoy once you get it all up to date again. JDA does a good job on the lines as well as I installed them on a 1982 CX500 Custom my son had last year before trading up to this GL1100 now....

Just got off the phone with Craig at JDA Enterprises. He does not have the specs for brake lines for our GL1100. He does have the specs for the GL1000. Does anyone know if they were the same? Thanks for any info.

Barely a scratch anywhere and not a speck of rust. I've had the privilege of restoring quite a few "barn finds" over the years, but this one was by far in the best condition. Other than draining the fuel and brake systems, I do not believe the PO could have preserved the machine any better had he tried! Below is a shot of the cluster and 'tank'. The speedometer still has the 600 mile service reminder sticker!

NICE bike!
I am courios, do the o-rings leak at the crossover pipes? Or any leaks at all? Mine sat for 5 years and darn near all the o-rings the bike had were shot.
They didnt leak for a couple of days of riding-then it seemed they all went at once. Regards, Johnyy

Johnyy, so far no leaks whatever. Even though I drained, flushed and refilled the cooling system, the old fluid was bright and clear so hopefully any rubber components were well preserved. I've only put around 70 miles on her as I am replacing the timing belts and setting the valve lash before riding much more. Time will tell if my O-rings are shot. I'll post if they are.

Timing Belts/Valve Adjustment/Final Drive Service

Postby doctorpaul » Sun Nov 25, 2012 6:05 am

Finished timing belt replacement and valve adjustment yesterday. Getting to those belts is a !@#$%! Gave me a good excuse to run to Sears for a set of Craftsman ratcheting end wrenches ($40 off for Black Friday!). Made removal and reinstallation of the cover bolts much easier as there is very limited space between the covers and the radiator. The Honda belts looked good but are 32 years old. A pair of Gates T274 belts was about $60 from O'Reilly's. I was unable to rotate the flywheel to view the TDC marks by turning whatever shaft (alternator?) is accessible through the port on the back of the case. I turned the 10mm nut clockwise about 1/4 turn but the flywheel never moved. Ended up bumping the starter (with spark plugs out) to get close then spot-on by nudging the rear wheel. The valves (engine cold) were all about 1/4 turn tight. I do not believe the 600 mile adjustment had ever been done as the service reminder sticker is still on the speedo face. Plan to service final drive today ... any problems using a synthetic GL5 hypoid gear oil? Thanks!

Not sure on the hypoid- I use Valvoline full synthetic 75w-90.
It does seem odd that you couldnt turn the engine by hand- all belts off and spark plugs were out? It allmost sounds like the nut on the end of the shaft moved and not the shaft itself. Regards, Johnyy

Timing belts were on but plugs were out. As best I could see in the hole, there is a nut on a slotted bolt .. probably the end of the alternator shaft? I seemed to be tightening it without moving the crank. I didn't want to push my luck in case something was gonna break so just nudged it over with the rear wheel. BTW, 'hypoid' is just the name of the pinion/crown gear relationship for most final drives. I've used Castrol Syntec in most of my shaft drive bikes with no problems. Older BMWs sometimes weep past the pinion seal a bit when a synthetic lube is used so just wanted check if anyone on the forum has had problems. Thanks.

I did my belts in Sept. The bolt head in that hole took I believe a 12mm socket. I did it with the plugs in. There was a bit of resistence but nothing that seemed unusual. My bike has over 30,000. I wonder if the newness of the engine made it hard to turn. I remember here in Chicago back in something like 1984 we had a cold snap. The temp with the windchill dropped to -60. I was in my early 20's and had an old beater Nova with a straight 6 and about 200,000 miles on the clock. Wouldn't you know it! My car was the only car on the block that started and I wound up giving everyone else a jump! I have always thought it was the fact that my engine was very shall we say broken in :lol: that allowed my car to start. Just a thought.

sounds like you were at the clutch adjustment.

to turn the crank it takes a 12mm on the back of the alternator and is located up high on the left aft side of the engine.

the clutch adjustment is low and on center below the crank.

you should make sure that the lock nut is tight and clutch adjustment is correct.

Definitely sounds like you were turning the clutch adjustment. The alternator/engine crank bolt is here:

You remove the cover, and the bolt you turn is underneath it:

You'll need this to do your valves as well. Have a look at How to adjust your valve clearances.

As for the rear end - you MUST use hypoid gear oil, as regular lubricating oil will not have the extreme pressure and antiwear additives required to lubricate the sliding action of beveled hypoid gears. As mentioned, Valvoline synthetic 70W90 works very well, and you will not have any problem with seals.

Look at: How to replace the gear oil in your final drive
