maxim81

my 81 has an everstart ES12A-A battery in it, made in japan. I'm not sure exactly what you are looking for on the other thing, but if you clue me in a bit I will look at my bike and see if I can figure it out.

Thanks for the info, today I pulled all 4 plugs, 1 at a time, they smell like gas and are very black, kinda oily looking. I wiped them off but they are covered in carbon. Haynes manual says fuel mixture problem. I haven't really done anything with the carbs other than pull the diaphram tops off and look in to see what it looked like in there. I already ordered some used coils, but thanks for the offr, I got them pretty cheap, hopefully they are good. Also I checked the air filter, it was fine. Is there a way to adjust the fuel mixture? Haynes manual mentions it then kinda never comes back around to it. Also I took the bike out on the road 2 days ago, I put 10 miles or so on it, it ran decent till the last mile, it pretty much died, kinda did a bunch of skipping sounds from the carb area, then it cut off, no matter how much throttle I was giving it would keep it running, just died. It wouldn't crank, I sat with it 5 min or so, still no crank, as a last ditch effort I turned the choke all the way on and it fired up and got me home. Thanks for any more info.

After trying some different things, I decided to leave the choke on while riding, runs much better with the cluth on all the way, does that help pinpoint anything?

I bought this bike a couple weeks ago. I was told the carbs were recently cleaned and synched. The bike sounds like it backfires/or misses though when it heats up some, 2-3min of running. The person I bought it from had the spark plugs changed also, and said that was when the missing started, the wires were not changed and he was told that, or the coils were more than likely the problem. Is there a way for me to test and see what the problem may be? I tried to see if I could see any sparks or anything in the dark but saw nothing, and the wires look to be hardwired into the coil. Thanks
