1980 GL 1100 "bang, rattle, pop" -have to make it back east

Postby mwatershoes » Tue Apr 26, 2011 2:29 pm



Hi there Guys,

So Im pretty new to the bike world, but last summer I inherited a 1980 GL 1100 with 24,000 miles, and after graduation decided to take the year off and tour the country. Since last August I have put 20k on the bike, and seen much of the states. The trip has been great, but its time to head back east.

Right now I am in Central California, and the bike is not running too well. At low RPM's, it sounds and feels like theres a few rocks being thrown around in there, and even at idle sometimes I get little backfires.

I have been good with oil changes, tires, and adding techron to the gas, and spark plugs, but I think the issue is deeper than that. Thing is I have to leave in two days, and am pretty broke. I dont want to get ripped off by the Santa Cruz mechanic who was kindof a jerk when I got some tires from him a few months ago...ugh god I just want this bike to make it back.

It seems like valve clearences and the belts might be a good place to look...(??) I do have some tools on the bike and am ok with minor work...the belt tentioning looks pretty easy but the valve adjustments not soo much. The rattleing has been getting worse as of late so Im just getting abit concerned about the trip home.

Going for another tire today and so Ill talk to the Santa Cruz guy and see what hes got to say but any imput from you guys would be great. Right now I am pretty sick of the road, but love this bike and want to keep it alive for a rebuild once back in new england.

Any tips greatly appreciated. cheers, mike.

These bikes are kinda sensitive to getting the same amount of fuel from each carb. My guess is there is a piece of crud in one of the carbs. Try some seafoam.

Ugly noises.Does it smooth out at 1500 rpm and above?Still pull good?Quiet running down the road?If yes to that and the rattling is at 1500 rpm and lower , the bike is suffering from the dreaded "carbs are gummed up,need syncing,trashy fuel,etc.scenario).Yes it's annoying,and difficult to deal with on the side of the road.But not detrimental.Unless you can remove the carbs(1 hour)and completely disassemble them,clean all the ports(3 hours)then put them back(45 minutes)having all the tools,space and supplies,,,,,I'd try like suggested above.Run a can of Sea Foam through it.It won't hurt,but can defiantly help. There is no looking at the timing belts,if you must...replace them(Gates brand at Napa).If the valves need adjusting,It takes about a hour and one soda.Look at the "how to"on this site.

I agree, it's the carbs being unbalanced that causes that noise. So what is the cause of unbalanced carbs? It could be one or more carb not performing as well/the same as others, it could be valves going out of adjustment. A quick dose of Seafoam won't hurt, and certainly after 20,000 miles the valves are in need of adjustment (the owners manual has you checking them every 8,000 miles).

I'd do the Seafoam clean, and if you can, do the valve adjustment. After that, the best thing to do would be to actually synchronize the carbs, but you likely won't have the tools with you to do that. Any decent bike shop would be able to do that for you in half an hour or so.

Thanks guys- Seafoam sounds like the word to me. I took the bike to the shop today, and Jim was great today, very helpful. He changed my tire for $30 when the other guys wanted $100 (jeeze). In talking to him I asked if my swiss cheese exhaust could effect performance at all and he said yes of course, so that could be a contributing factor. -Will go to the auto parts store today for exhaust tape and *seafoam :)s

WOW!!! guys my 83 1100A was doing the same thing. "Bang, Bang, Rattle, Pop" a few days ago i was working through a battery problem and with a good battery it just loped and then stopped after hitting it a couple times it turned over good and started. It was making "that noise" at low rpm and went away after reving. then it got ugly. it started running rough and not idling. it just got wurse then died. It turned over very well and fast but no fire at all. I read somewhere in a forum that the timing belt will break when it goes. I took the covers off and they are in tack. I think i will move forward with new one at this point and hope it is all it is. but i do also believe you guys about the carbs and valves. I has 35K and the belts are marked "Honda" The guy I got it from was a car guy and decided a couple years ago he wasn't a bike guy and left this jewel outside. I will appreciate any input. :shock:
God Bless those who ride and keep them safe, Amen

Virgil, the powerband is effected the whole way. When on the highway, if I pull it hard, there is hesitation all of the way...feels like it has something caught in its throat and cant cough it up.

An update on the Seafoam; put a can of it in there and it definetly helped. I am in Reno now, with no trouble getting here, and see smooth sailing for the next 3k back to the east coast. Thx for all you r help guys! Cheers!!

The old wings are amazing.I've never been left by the side of the road by one.they always seem to be able to get home.1 seized caliper(25 miles home),one time only running on 2 cylinders(35 mile drive) broken throttle cable(hunk of wire on the road worked,20 mile run).I've even passed broken down HD's while limping back.
