hesitation

Postby rescue1042 » Thu Mar 22, 2012 10:24 am



Ok guys i have a question for you all! I have a 1982 honda gl1100 that has a hesitation at mid range it idles great and when you can it to pass it starts to flutter but then it comes out of it and goes like a raped ape then it like bottoms out at about 7000 rpms and wont get to red line it does it in all gears and when cruising in 5 th gear and you turn throttle it hesitates pretty bad on load.

I have put in all new carb parts including needles and seats new belts and adjusted the valves i have also done the sync to carbs and starts and idles like a dream.. new pulg and wires. and adjusted 3 turns out on pilot screws i have had carbs out 5 times and everything is clear
Would like to know if anyone else has any ideas of things to check
i love my wing but this is getting to be a big downer ;( so looking for the first camp trip of the year this weekend but kinda bumbed about problem any help would be great!!! thanks for your time!!!!

Lets think a minute......
you can it to pass it starts to flutter but then it comes out of it .....
then it like bottoms out at about 7000 rpms......
it does it in all gears and when cruising in 5 th .....

This really sounds like a air flow problem.
My first test is easy.
Borrow your wifes compact mirror.Stick it to a piece of clothes hanger wire at a angle and stick it down into the plenum box.With a light,you should be able to see the slides.Rap the engine up and verify that each one bounces up.If the slides are sticking,it will show up here.
My 83 preformed badly.I had just one slide that wouldn't move at all.

One other thing I'll mention.
Pop off the oil fill cap and start the engine.At a idle,does it seem to have too much blowback coming out?
My 78 did,a lot.
I found that one exhaust header had a swollen inner thermal liner that restricted the exhaust.It backed up into the engine causing poor performance.Again a airflow problem.
Obviously all this is assuming that the plugs are gapped right.
The timing is pre-set but it is also controlled by a vacuum line that goes from the carb pack to the back of the engine onto a vacuum canister.
Might as well check that too.There is a vacuum only when the throttle is opened up,none at a idle.Draw a vacuum on the canister and listen for movement and that it holds a vacuum.

A vacuum in the tank is a problem.If the caps valve is not working,it can fuel starve the engine.If you suspect this may be the problem,run it with the cap loose.
There is a 1 way valve in the gas cap to prevent a vacuum,however,don't confuse it with a pressure buildup.All my bikes,the next day will create pressure in the tank from cooling and heating of the fuel.During the cool night the tank will allow pressure to equalize and then the cap seals it off during the hot part of the day increasing pressure.So every time I take off the gas cap I hear the Whoosh,but it's releasing pressure not a sucking sound.
When I do carbs on the bench,I use my shop vac attached to each carb in turn and operate the throttle to verify slide operation.
I also fill them with fuel to verify a good seal and then drain each carb to measure the for even amount in each carb.
1 mis-adjusted float can lead to a single carb running rich or lean and really foul up trying to get it to idle right.

just a update i replaced the fuel pump and took it out and started down the road and all of a sudden it started really poping and started loosing a lot of power! got it home put old fuel pump back in and now will barely run! i can now hear it pushing back against the carb and pops and will hardley run exhaust is going back in to carb and when i pulled the oil cap off i is sending a lot of blow back thru the whole, prob valves? it is knocking pretty bad on left side, pulled plugs and they look good and have spart and i know there is gas, doesnt sound good to me :( anyone need a lot of good parts??? if anyone has a brite idea send them my way Thanks guys!

so i decided to dig into the problem a little more and descovered that the slides had some scuff marks on them so i shined them up and and took the lips off and took it for a drive I have to say it is way better then it was way more power! still has a little spit and sputter when start twisting the thorttle but not as much. it is so much better!!!! then of course my radio didnt work to good so i went to walmart and bought a new radio and speakers for front and installed them works good! then got a hair up my butt and installed rear speakers in the trunk now i have surround sound Love it!!! and doesnt look to bad either! I so love a goldwing it rocks!!!!!!

Sounds great.Those slides can be finicky.They have to operate butter smooth in the caps.And I always test them with a shop vac before I put them back on.Sticking a compact mirror in the plenum box on a angled stiff wire will allow you to see each slide and it's movement when rapping the throttle.

And my home brew carb sync...This thing will pull from 800 rpm to the red line clean....viewtopic.php?f=16&t=8994
