83 gl1100 interstate problem

Postby Swamp donkey » Thu Sep 26, 2013 10:59 pm



okay guys and gals here is my problem and I'm open to all suggestions. I bought the bike couldn't get it to start dumped fuel in the plenum and it would start but wouldn't idle or rev without adding fuel to the plenum. took the carbs off,( tonight makes the 4th time), put new kits in all the carbs tried to sync and couldn't get close it even close. noticed after changing the jets and things that I had no vacuum on the #3 carb( is this a problem at idle?)checked all the vacuum chambers(I did mix those up!!!!).the float levels are spec, in the end I put everything back (old jets and brass parts) that wasn't worn. I didn't bench sync at anytime but I did buy a synchronizer from motion pro and I got the carbs very close. as a matter of fact it running better than I ever had it running, lol. But it still has a miss starting around 3000 to 4500 rpm's you can feel it try to pull out of the miss like it is going to clear up and does if you can keep it above the 4700 rpm range. this has been the case since the 1st carb removal the miss has never got worse or better. what kind of other problem should I look for? go thru the carbs again?, replaced plugs, fuel filter, any help would be appreciated....

Do a compression check to make sure all cylinders are ok.

Check to see if your vacuum advance is stuck,it has two levels of advance one is mechanical the other is vacuum. 8-)

I like how you are thinking, tell me more about the timing advance, where it is at sheer to look and so forth. To be honest I knew it had to have something like that but I don't know where to look. And I did valve adjustment tonight # 2 and 3 and it has improved! But not fixed. Again any help would be appreciated

Could be that it's just dirty wires or bad connection too but here's a video of the vacuum advance in action with the engine running...Pretty cool stuff we have here..

I removed the swingarm for this video..

The video that our friend Littlebeaver was kind enough to make for us shows the advance mechanisim in action. You can find it at the rear of your engine just inboard and above the driveshaft. There is a small black hose that gets vacuum from number 3 carb, it may be either damaged or not hooked up. You are going to have to remove a few items to get a good view of it. Let us know what you find. 8-)

Ok I tried your trick with pouring fuel in the plenum. started kept running, but back fires out left side. heres the thing that scares me although it will start now with out pouring fuel in plenum. warm air coming out right side exhaust but cold air coming out left side. whats up with that am I not firing on the right side plugs... oh lord or worse.

A quick test to see if all cylinders are firing somewhat equally is to squirt some water on the exhaust headers after the bike has had a chance to warm up. If you get a good sizzle after the bike has warmed up then its more or less OK. If one (or more) headers won't sizzle or aren't as hot as the others then that cylinder is probably not firing as it should. Might help you to narrow it down. Another method is to get an inexpensive IR heat sensor (Harbor Freight sells one) and check the headers with it.

Chances are though that you still have a mid range circuit plugged in one or more of the carbs.

Update on my 83 Goldwing... book hasn't arrived yet uuuugh... belts will be in tomorrow. I read up on a link from another site, how to change my belts and found that the left side pully or if facing the bike right side was advanced a little so I took old belt off after following the process and held the pulley in place while reinstalling, granted the old Honda 62000 mile belts lol... still have to pour gas in plenum to start... sitting on the bike the left side exhaust is still cold air... but oddly enough it sounds like a motorcycle idiling now. When book gets here am going to tackle the belts with new and still intend to rebuild or have carbs rebuilt. Any suggestions other than carbs I may try I am willing to. I like tinkering with it lol. Pretty easy to work on so far. Im not sure if I have the temperament for carbs. hehehe.

Good lord as I stated earlier, got my timimg belts... ready to do them but think I have another problem to tackle. I removed radiator to do the belts the other day antifreeze nice and green so it seemed drained it moved the bucket to the side not really lookin at it. got everything prepaired and apparently the oil, yes oil was up in the reservoir because now that I have looked at the bucket of antifreeze it has a good amount of oil in it dang dang dang. What do I do? At a minimum at least I must do the head gaskets correct?

Possibly waterpump bearing and seals. Look under the cover and see if you have any wiggle
in the impeller shaft.

It may be the water pump but more than likely you're looking at head gaskets. They are not hard to change, the OEM manual is very good on the subject. Do both sides. Seems folks that do one side only end up doing the other side within a few hundred miles.
