Bucking at Higher Speeds

Postby rjbrownley » Mon Apr 16, 2012 10:37 am



I have a 83 GL1100I. My problem is, if I am cruising along at around 60mph and go to pass someone and hit the throttle hard, my bike bucks and will not go pass 65mph. But if I slowly increase speed, then it is not a problem. Any help would be appreciated.

Or the slide/slides are stuck.
Stick a compact mirror(your wife needs a new one anyways) on a bent piece of wire in the bottom of the plenum box.You can,with a flashlight,see the slides.Start the bike and rap the throttle to see if each one pops up.
All it takes is one stuck down to drop off the power curve by 30%.
A bad accelerator pump may be more noticeable on a lower speed/off idle hesitation.

My 1100 ran just OK but was a bit doggy around 3500 rpm when I got after it.
I bought her a new mirror and stuck the confiscated one as described.
I found all but one slide working.One was stuck solid.It was a 1/4" size spot of oxidation on the piston.
Polished it out and now it out runs my 1200. :D

Ever sense that episode,I use a shop vac on each carb to check the slide movement before I put them on the bike.

I wouldn't risk spousal fury...telescopic inspection mirrors can be had for under $10, and they let you position the mirror at the precise angle you require:

I looked at my carbs last night, but was not able to figure out what you are calling slides. Also, last weekend I adjusted my lifters, so maybe I need to sync the carbs?

My '77 GL1000 speed dropped off the other day. Turned out to be a bad Emgo Fuel Filter.

My '82 Wing would not go over 65mph when I first bought it. When I changed the sparkplugs,it cured the problem.

Well I changed the spark plugs and cleaned the slides. Then I tried syncing the carb, but was not able to. I followed the "how to " instruction, but the needles on my gauges move too much. Any ideas how to settle the needles down? I did use the aquarium valve, which did not help.

You should be able to close the valve off enough so that the needle on the gauge is just moving

Did you use the scew type valves? That makes a difference. They make different types of aquarium valves.

Also make sure the valves are as close to the intakes as possible, so the air in the tube between the valve and the gauge is used as a buffer to dampen the oscillations.

I do have the screw type valves. I have to close them just about all the way. When I try to adjust the carbs, the bike starts to rev.
