Poor Power

Postby patbrandon1 » Tue May 01, 2012 12:29 am



A few days ago, I was riding my 82 GL1100i and about 2 miles into my trip the bike started to have no, to very little power upon acceleration, and it wanted to stall without keeping it revved. It seems, the more gas I try to give it, the more it struggles. It's like it is struggling for fuel. When I let up a bit, it does not struggle so much, but it still has very little power. I searched through all the posts I could find to try to fix the problem. I have done a few things, and will be getting a set together to sync the carbs. I did put seafoam in the tank and went out tonight to run it as much as I could. On a few occasions for a few seconds tonight, I was having full power, but it didn't last very long. It was cold out lately. Do these engines dislike cold weather? I read tonight that I could loosen the gas cap and see that it is allowing air through, but have't tried that yet. But if it were out of sync carbs, can that happen all of a sudden??? I looked in the plenum with a mirror, and the slides seem to be doing their job. I am just confused as to why I am having full power every once in a while. I will try new gas tomorrow, and check for vacuum leaks, loosen the gas cap, and keep you posted. And suggestions would be greatly appreciated.

Check your fuel filter for junk. Look at your plugs, are they sooty or wet ( stuck floats .. no, or intermittent spark )? Could be one of several issues going on? Bad fuel, bad plug (s) weak coil, electronic ignition starting to fail, etc.

SOLVED!!! Changed the fuel filter last week. Changed the plugs two weeks ago. I pulled the plugs Sunday to see what they looked like, and they looked fine. Pulled them today and they were black, well, the #1 and #3 plugs were. 4 & 2 were okay. So I changed the coil (had an extra one in the little box of stuff that came with the bike) put in new plugs, and now it runs better than ever. Thanks for your suggestions D2D. I'm still going to sync the carbs this weekend, and plan on a carb inspection this winter. But boy is it nice to have power back, almost as good as...well you know, a bowl of ice cream. ;)

I was going to ask, How much fuel was in the tank at the time, the reason I'd ask is because that happened to me once and I realized my fuel gauge was near the res. area so I turned the fuel petcock knob down to res. and it cleared up..But it's good you figured it out.. :D
