Runability problem 82 gl1100 interstate

Post by Lewi52 »



I have a 82 gl1100 interstate with 39k on it that i bought as a project bike. Love the bike but i have a head scratcher of a problem with runablity. The bike starts great idles smooth and has all sorts of power in 1,2 gear & partially in 3rd. When i get into 4&5 on hard full throttle it skips going up hill & my friend was riding behind me said he saw small amount of black smoke out of both exhaust pipes. Flat land & highway when getting on it not as noticeable. So this is what i have done so far 2 try 2 correct the problem. New NGK plugs, & air cleaner, replaced coils & coil wires that i chked with a v.o.m, have constant 13.5 volts @ all times @ the coils, balanced carbs, have been running seafoam through about 6 tank fulls, and btw really like the product!! Replaced fuel filter & chked fuel volume & pressure @ fuel pump is 2 to 3 psi up hill full throttle. Blew out fuel lines & finally i sprayed carb cleaner in intake @ 3k rpm a squirt @ a time so i did not make it die. I am @ a loss on what is causing the problem 🤔😠? Any suggestions would b appreciated. I have a hard time thinking the carbs need 2 b rebuild cause in 1&2 hard throttle up hill np so that 2 tells me the power curcit in the carbs is ok & float level is fine. Also last but not lest it seams better the higher the rpms when shifting the less it seams 2 skip or stumbles! & my milage sucks & 35 mpg . Would valve lash or timming b off cause it? Thats the last thing i was going 2 chk this weekend. HELP !!

Those coils you put on, were they new, used or a different type of coil? Sure sound like an ignition problem to me.

An ohm test of coils is useless most of the time. Doesn't matter how many miles on the coils, it's age that gets them and they're still 36 years old. At least 1/2 of the 1100 coils I've seen have been bad. I have had at least a dozen 1100s and I have put a neon coil on most of them.

So let me get ur thought process straight. U believe that the spark is not hot enough durring hard throttle in 4&5 gear therfore not igniting the fuel properly that is y i am getting the black smoke? I Have chked my plugs 4 a rich mixture but have found the plugs burning properly. I am a little confused by the spark is hot enoght in 1&2 but not in 3-5th? Again this is full throttle in all gears.
I really like ur idea & willing 2 give it a try. I am sorry if i missed the part did u use the same heat range plugs & same gap?

The more the load the harder it is for the spark to jump the gap. Used the same plugs, .035 gap, it's in there somewhere but there are so many posts in that thread it's hard to find.

Sounds like you need to take the carbs off and clean them out. Can't speak to electrical issues, especially since you are getting spark. In fact if this bike is new to you here is a really nice list to go through.

Written for a GL1000 but appropriate.

I'm curious as to how fast you're going in 4th and 5th when the bike is stumbling out. Full throttle in high gears when you're going too slow will cause it to lug down. I don't usually click into 4th until I'm at about 45 or so, and don't hit fifth until 65. You have slightly deeper gearing on your 82 than I do on my 83, but the though process is still the same.

I thinking you might just be in too high of a gear. These bikes like some RPM.

Not if you have a good hot ignition system. You can lug them down to idle speed and pull away without a hiccup.

Update! I could not find a 97 neon @ junkyard today so i grabbed a 97 subaru legacy coil pack. Wired it up without ballast resistor & fired it up & took it 4 a ride . Same problem😩 ! Runs great again except 4 the same hard stumble on heavy exceration. Does anybody think it will hurt if i run with out resistor? Not sure this coil pack is as hot as the neon? Can anybody tell me how i could tell ? I guess i am just Having 💩 Luck!
