Throttle response question

[NJOutlaw]

Hey gang, my question is how to get proper and crisp throttle response? The PO SAID He added over sized jets, but the bike runs decent but from stop theres a slight delay in throttle twist and actual bike response how can I correct this? & it seems to run a bit fast as well as slightly rich. Thanks in advance.

gee this can be a wide ? as the problems here can be and useally is ignition and carbs .... the 1100 is so interdependent in this area ... and our very user unfriendly set up ...thanks to epa idgets ... star by unpluging vacum advamce and such on the end and see if you can feel the advance plate moving ....then plug ends and wires probably need to be check for great spark ... look at the igniters under the shelter to see if there melted any from aged related heat build up ... then carbs are useally plug up some in idle circuits and the liitle filters under the floats seats ...gee could go on awhile about this ...im certain a fix is always there in a bike that seems the lower end is good

+1 on Joe's suggestions. Some have run ATF (automatic transmission fluid) in the gas to clean the carbs and swear by it. I think they run 8 Oz. per tank. If your ignition isn't quite up to par, and most aren't on a 32 year-old bike, the C5 ignition system will make a huge difference! Not really cheap, but oh so worth it!

If you're up to the task of pulling the carb rack, a good cleaning would also work wonders. You say it's running good, so you probably don't need to replace anything, but sticking sliders and slightly clogged jets and passages can be made like new. On your '82, the idle/low speed jets can be easily removed. They're pressed in on earlier models.

It also sounds like your accelerator pump may not be working, It provides a shot of gas when you twist the throttle. The diaphragm can go bad as well the tiny orifice can get clogged. A somewhat simple way to check would be to remove the manifolds and twist the throttle, you should get a spray of gas from each carb, It may look mor like a drip with the slide in the way because the orifice is behind the slide.
You can also as well, or instead remove the cap and slide and then twist for a better visual.
These orifices are as tiny as a human hair so it doesn't take allot to clog them, sometimes the pump diaphragm breaks down and bits of rubber clogs them or the screen under the float needle breaks and slowly lets in tiny contaminants and over time will clog them.
I had only one working on mine and it took some tiny wire, a pair of forceps and quit a few hours to unclog mine but it makes a difference.
When rebuilding the 1100 carbs "clean" is important.
I just realized you posted this in the 1000 section, the accelerator pump is only on the 1100.

Thanks for the replies.. Yes Jeff I just realized that also...

One last thing to consider. If the previous owner had clogged orifices in the pump circuit he may have been trying to compensate for it with larger idle jets so if you do dive into it I would have on hand the stock size jets,
If they are clogged then unclogged and you keep the oversize jets it may be too much fuel and cause problems you will continue to chase.
The way I see it is that Honda took allot of care to get the jetting right and short of major engine modifications the factory jets should be fine.
