Throttle response

Post by TwoTone Trike » Sat Jul 15, 2017 11:54 pm



I recently purchased a 1999 Goldwing 1500se Hannigan trike. When I try to give it gas on take-off it bogs down to the point of stalling out. If I just ease the clutch out without rolling on the gas it will go on. Is that just the nature of the beast? Also after rolling when I hit the throttle there's a hesitation before it goes on. I've changed the air filter, sub filter, cruise filter and the fuel filter to no avail. I'm not about to let a Harley leave me at the line! Don't get me wrong I have nothing against Harley's as I've owned Harley's for the last three decades. I rebuilt both my 53 Panhead as well as my 73 ElectraGlide and when I snapped the throttle on them they would snap your head back. Due to an accident in 2008 I am no longer able to ride on two wheels. I test rode a Harley trike but it was to uncomfortable, but the Goldwing felt like an easy chair. So back to my question. Could the carbs be out of sync? What gives. Any help would be greatly appreciated. Thanks, Tony

My '94 had a slight surge at idle, and seemed to have a slight "delay" when rolling on the throttle. Took it to a mechanic and he determined that the slides were sticking. He is rebuilding the carbs for me and I should know in a couple of weeks if he was right!

People will say "Why is it taking so long for the rebuild?" - Well, we went on vacation a few days after he got the bike and we'll be back home in 9 days. Figured he could work on it while we were gone and we don't lose any riding time!

What is the mileage on your ride, did it sit around unused for any length of time? Sounds like it is running lean and is usually due to carburetor troubles and/or vacuum leaks. The 1500 has a number of systems which need checking before a definitive answer as to what the problem is.

No, the bike was being ridden when I bought it. It has 109,000 on it. I changed the timing belts, the tensioners, the air, sub, cruise and fuel filters. Alan hit the nail on the head. The slides were sticking. I ran some sea foam through it and now it's running great. Thanks for the suggestions though. It's nice to know that there are so many members willing to lend a helping hand. Thanks a million, Tony

When you say you ran Sea Foam through it, does that mean directly through the carbs, or in the gas tank?
I seem to be having some of the same symptoms.

I ran about a half a can through the gas tank. Hope this fixes yours also. Good luck, Tony.

Sorry I forgot, that's about a half of a can to a full tank of gas. After you run the first tank of gas out you may want to treat it again. Tony.

I like Sea Foam as a general maintenance item, not sure it would really help the slides, but apparently it did for you. Must have been gum products on them.

On my '94SE the slides got jammed up with flour fine sand.....
I literally had to remove the tops to see what was going on, and used a carb cleaner spray and a tool to work them up/dn until they turned loose and worked freely again....

long story behind the why, I got diverted off the "right road" onto one that ran out of pavement and ended in flour about 2 hours past dark thirty.

1/2 can per tank is just right for routine "keep the varnish out"....
I just did that even for my 1800 which is EFI, not carbs.

Yeah Seafoam isn't a cure all but it sure is good at some things. Keep the rubber side down.
