After getting onto the freeway at doing about 65-70, my 82 GL1100i started surging/pulsing. If I release the throttle, with clutch in, the motor would instantly die out. I noticed that the clear fuel filter that I'd put in just a few weeks ago was pretty dirty, rust, dirt, etc, but especially noticed that it was empty despite a full tank of gas.
Paying close attention, even after replacing the filter, I thought that the motor was cutting out due to lack of fuel, it pulling more gas than could be supplied. At first start of the day, the filter is visibly full, but by the time I made it to the freeway, the fuel filter (not oem) was drained most of the way. Hitting the speed limit, within a few minutes, the pulsing started, and same condition as with the old filter. Since the filter was empty, I thought it must have been the supply from the tank, maybe a stopped up pickup tube, or clogged petcock... When the filter was empty, the trick of fuel to displace the air was a slow process--with motor off, taking about 1 hour to refill. It turns out, it wasn't that the fuel wasn't being supplied fast enough, rather, I think the air had nowhere to go.
I tapped a small vent hold into the filter, as a test, and with vent open, the filter fills quickly, however didn't solve the surging problem. Once the surging started, it kept on until the bike was stopped for a while, probably the bowls needed time to recuperate.
Took apart the pump, cleaned it, even though it was moving fluids as expected, all was fine inside.
Now, I've begun taking the carbe apart, and as I'd been suspecting, they need a full workout. I'd just gotten this bike a little over a month ago, and SeaFoam treatments and soaks had gotten it running fairly good. I thought I'd gotten away without taking this "sat in the backyard for a year" bike's carbs. Clearly, with carbs out, and taking apart #1, it's got lotsa clogging. The small jet though, is stuck in the tube, with no 'slot' for a driver--it was smooth and I can't yet extract it. I pulled #4 apart, it too had lotsa gunk/chunks, etc. I did get the small jet out just fine on this one. Both big and small jets had the teeny tiny holes plugged up pretty solid.
On the small jet of #4, the main channel was completely blocked--very solidly. It is supposed to go thruough, right, like the big jet? It took some effort, but I did get an opening all the way through the small jet.
Just want to confirm, the small jet DOES go all the way through, right? The rest of the components inside the two carbs actually look pretty new, the float bowl gasket, float pin, and other parts, while a little caked with crud, were, once cleaned up, very tactile and resilient. The carbs must have been overhauled/rebuilt recently (perhaps just before the 1 year backyard tour. I'll be reusing the existing runners, especially if cyl 2 & 3 look as new.
So, the small jet is still stuck in #1, with it's slotless head all the way in the channel. IT must have been worn smooth from someone's previous efforts to remove it.
Any tips to get this small jet out without a scredriver slot? Gonna give it and easy-out attempt.
If I do get the small jet out OK, I'll have to dremel a slot into it to keep it useable. Will the functionality of the small jet be impacted by the effective removal of the top 1/4" of material? If not, I'll groove a new slot, and move on. If it IS impacted bya haing a shorter top, anyone know of a Phoenix area cycle shop that might have thison the shelf/instock? I need one pretty quick, this bike's my daily ride to work. Anyone have a small jet for a gl1100 82 that they cna send? Happy to pay if you've got one.
