1981 gl1100i driving me crazy!

Postby darrell.berdine » Mon May 28, 2012 1:40 pm



Hi guys, I bought a very neglected 1981 GL1100 a couple of months ago. So far I have clocked about 200 miles and about 200 hours working on it. Long story short or sort of short, it blew the right head gasket shortly after flushing the cooling system, I replaced both head gaskets, timing belts, water pump, and thermostat. Got it all back together and it rattles, pops through the exhaust, and sometimes spits back through the carbs. Thought maybe I screwed up the valve adjustment so I rere adjusted them. They weren't far off maybe a .001 off to loose. Decided I must have gotten one of the timing belts a tooth off, so i pulled the radiator again and checked the timing marks, they are dead on. The bike ran decently before this. It actually sounded better with a blown head gasket running on three cylinders than it does now. It would idle and was not this noisy. I'm afraid to run it very long because it sounds so bad. It does smooth out a bit above 2000 rpm. Any thoughts or advice woul be awesome. This is my first Wing and the first metric bike I've owned in 30 years. Not sure where to go next.

If the timing looks to be correct and valves are set right I suggest doing a carb sync. If the carbs are out of sync the bike will run rough and it will sound like it is out of time. Try to sync the carbs.

Thanks seabee thats what I was thinmking too but wanted to make sure I wasn't overlooking something I had just done. Any of you have first hand experience with Randakks master kit? Thats the way I'm leaning since every gasket on this machine seems to be failing now that I have it in my garage. LOL

Randakks is the best quality. I have not used his kits yet but plan on it this winter for my carb overhaul. Everyone speaks highly of his kits on this forum and many of the other forums. If you want to do it right the first time use his kits.

When you replaced the timing belts, did you notice that on the right camshaft pulley, the correct timing mark is the least noticeable? Guess how I know this. See picture (below ad at the moment).

Thanks I checked the timing marks just now, and they are correct. Goess I'm doing the carbs next. Just ordered Randakks master kit. This bike is 30+ years old and only has 20k original miles on the clock. It has spent most of its time sitting in the yard under a tarp.

the air valves in the carbs are prone to rot out, mine was the same way when i got it. it causes the bike to run over lean at part throttle

i had an 81 wing and it ran a little rough. I bought the mercury sync tool, adjusted carbs to sync, and this made run nice and smooth. It was easy to get to carb ports to do so compared to my 93 GL1500. good luck

Make sure you are on the T-1 mark and up is up on the pullies and then double check your marks..

Thanks Guys, I've checked and rechecked all the timing marks by the service manual and from your suggestions. It just about has to be something else. My carb kits should be here tomorrow. I will let you know how it turns out. BTW littlebeaver you have a great looking 81 hope mine looks that good someday.
