GL1200 Problem

Postby Poohman » Tue Nov 08, 2011 6:35 pm



Just want to see if anyone could let me know if I am going in the right direcion or not. I took a ride on my 85 GL1200 Apsencade and everything was fine the after about 35 to 40 minutes in my ride I had to pull over and make a phone call. Well after that I stated the bike and it ran like the timing was off or something. It didn't want to run and sounded rough. It sounded like it was back firing through the exhaust and the carbs but i really could not tell. I am wondering if it is out of time or do I need to get new timing belts. I have changed Plugs, Fuel Filter and have used Sea Foam in the gas for about a week now on a full tank of gas and it seemed to help the carbs. I really could use some quick help. I have a Ride coming this saturday with the guys at church and really like riding. :D

timing belt are cogged and generaly don't slip or show wear they just break. if you are using seafoam to clean your carbs its more likly that you carbs are too dirty for seafoam and need a rebuild

Check those vacuum lines. Especially the one to the ignition control unit and another valve up by the fuel cap. Mine is mounted to the bottom of the top shelter. But mine is a CA model......smog stuff I'm sure. Anyway check to make sure a vacuum line didn't come undone as this will cause the problems you are reporting.
Also make sure you have not added to much sea foam as this will cause problems.
Just noticed you had a prior post on the same problem.
Enjoy the ride. They are all good, just some better than others.

Just found out that my Problem is the Fuel Pump. It wasn't sending enough fuel to the front carbs to let it fire. I have heard that you can use a 1985 Honda Prelude Fuel Pump. It say's it is 2-3.5 psi. It looks like a compairable pump and It is much cheaper than Honda's replacement Fuel pump. The one for the gl1200 Aspencade is $200. and I can go to AutoZone and get one for $62.00 Just wanted to make sure that this is a good replacement.
