1987 GL1200 Interstate

Postby prowler-mc » Fri Apr 15, 2011 12:31 pm



Hello all,

I am a new member. I recently bought my '87 Wing and I am enjoying the bike. This is my second one (the first one was 1984 Interstate), and I am concerned about something. I was out riding one sunny Sunday afternoon. I was cruising about 75mph and when I went to accelerate, there was nothing there. I have been told that with Gold Wings, you can't/shouldn't go full throttle all at once. You should gradually roll the throttle. Well, this day it made no difference. If I gradually rolled the throttle or gave it all at once, my bike had no more power to give. The plugs and air filter are new. Any ideas, suggestions, or help??

There's no harm in rolling throttle on quickly, apart from low speed where you can put strain on the drivetrain - but at cruising speed, you're not doing any harm.

If you're not seeing the dramatic acceleration from 75 mph that you want, then you need to:

- Downshift first
- Buy a 1500 or 1800

The 1200 only has so much torque and horsepower, and cruising at 75 mph, you're already using a fair amount of it. :)

If you're saying that at 75 mph, you opened the throttle and there was absolutely no acceleration (and you weren't going uphill)...ok, well then there could be something wrong. Was the fuel reasonably new?

I just filled the tank (premium fuel), and was cruising away. I am considering replacing the exhaust, just is case I have an exhaust leak. I also ordered a K&N air filter. I like the idea of a 1500, but that won't happen for a little while.

My 86 will go faster and yours should too! When was the last time the fuel filter was replaced? I have been a auto dealer mechanic for 20 years and am a FIRM believer in OEM parts. pay the extra for a Honda fuel filter .
That is a guess tho. What is the fuel pressure? volume? any problems below 75mph? exhaust restriction?
Brakes dragging? intake air restricions? I don't believe they have a shut down RPM (rev limiter) so if you are mechanicly inclined and can do some disagnostics. Buy a Honda service manual too.
If not i suggest finding a good mechanical freind.
Good luck Joe

I was riding my 84 Interstate and had the dame problem. I went to pass someone at 60mpr and when I opened her up, she didn't want to go much faster. I know there is a little weight diff from my 84 I to my 83 v65 magna, but a 1200 down to an 1100 you would think the 1200 should give a little kick. The 1200 Idles fine runs smooth, but the upper power just fell out that day. I do more riding in town than out right now, but I think there is a problem. I can only get about 100 per tank full in town, +or- 10 miles. Right now I do drive like grandpa :lol: I'm just woundering if my cdi is advanceing my timming correctly. I don't have the special siteglass so it makes it hard to check the timming. One thing I would have you check is the venturies, make sure they move free and have now vac leaks.


How many times do I have to tell ya,,, The right tool for the right job!
