Topic: bike won't return to idle

[Texasstave]

Howdy folks!
 Just bought a 74 750k.When I went to look at it I was able to get it to run well enough to hhear that the motor was good. Brought it home removed the carbs cleaned and rebuilt them using 115 pilots and I moved the needle down one notch (in the rich direction) from center and bench synced them.I followed the advice of the local classic motorcycle parts guy for the jetting and setup. I'm running pods and will soon replace the ratty stock exhaust for a 4 to 2. I installed the carbs and the bike started almost immediately.I warmed it up and got a smooth idle.Problem!When I twist the throttle and let go the bike hangs at around 4000 RPM's and slowly returns to idle.I adjusted the air screws out pastthe 1.5 initial setting and it stayed the same. I got it to return nice when I turned the screws all the way in.Any ideas?Should I back The needles back off to the center hole?Is it still pulling gas once the slides have shut?BTW. I searched for a while for answers for this but couldn't fibnd anything that fit. Forgive me if ther's something there that I didn't see.

That's usually a sign of a lean condition in the idle circuit. I'm not familiar with the 750 cars or I would offer more advice.
My 500 is doing the same thing, I'm beginning to hate pods, and the rjetting and recalibrating the carbs that go with them. Unfortunately my bike came with them.

i think if you scour with the search function youll find pod stuff,it is a lean out,unstable idle,itll be ok cold ill bet but go crappy after a warm up?try and find the airbox  for it,115 i think you mean main jet?what slow jet has it got now?try the next one up,if you have duplicate spares buy a drill bit to suit.

Pod haters, ugh, I run them on all my bobbers and chops.  You may have a vacuum leak around the stiff rubber boots or a pinched throttle cable.  When you let go of the throttle it should snap shut quickly and firmly.  You might also try another notch down on the needle and then bigger jets if that won't do it.  I use a micrometer and gradually drill my jets larger and larger to find the sweet spot.  Don't forget to file off the stock numbers so a future owner knows the jets have been jacked with by a lower form of life and they can purchase a full set of shiny ones from Honda at full retail.  :-)

im with kingcustom on the filing off jet numbers youve drilled,i do that,i also mike drills ive bought and go by my mike,i have a #57 which should equal 1.09 mm,i mike it at 1.06,,and .45 mm i bought i mike at .44,ive miked my good set of feelers and its spot on,,jets in aftermarket kits might be a little hay wire.,im not keen on pods though,i think theyre too exposed to the elements on a streeter.

Are you 100% sure the slides are closing? Take the pods off to look and verify. Could the cables be in a bind or the slides? They could be and the vibration from the motor running is letting them gradually close.I'm a carb hater too but they can be made to work.

I would put one of my bikes up against anyone running pods and guarantee mine would run better to redline and i don't have to worry about cross winds and rain and what ever else those useless pods do, not to mention the ugly sucking sound the stock carbs make with pods on. I don't hate them but there is no way in hell they are better than the stock airbox for stock or warm motors and they are miles harder to tune.....I am here to provide some facts to the guys that are told here that pods are better....they are not.
Just remember that you build bobbers, i can also say that my bikes would eat yours alive in the twisties. I like building reliable sports orientated bikes, not tuning nightmares and pigs that don't handle.....Horses for courses i know but not my cup of tea at all.


PS....most bobbers and chops don't have any room for the airbox, thats why you have no choice but to use pods......lets stick to the facts here please..

Did I say pods were better than a properly tuned stock airbox, in good condition, with a clean filter?  Dick?

[DavePhipps]

I just wanted to add that my bike was doing this. I have a 72 500, Motad 4-1, and pods.
The stock air screw setting is 1 1/8 turns out. I had to take mine to 1/2 turn out.
Also keep a notebook handy, and record how each change you make effects carberation.

Keep your name calling to yourself mate it shows your lack of intellect.

And, NO, you failed to tell everyone that pods weren't as good as the airbox and harder to get some some type of tune  so that is exactly why i did.......don't let the truth get in the way of a good story....right....

And if anyone else wants more information just search pods....its all there...

The term "pod haters" is too specific.  It's more like haters of "performance" mods that in many street applications actually hurt performance.  Or haters of aesthetic mods that require way more compromise in performance and/or time and hassle to accommodate than they're worth.  Other forum favorites are super-wide tires, clubmans, electronic ignitions, in-line fuel filters, lowering blocks, taller gearing, etc.  (three of which I currently employ on my bikes )

I'm a firm believer in "it's your bike, do what makes you happy", but at the same time it would be nice if each person had plenty of info on the changes they're thinking of making, and it would also be great if everyone were honest with themselves and everybody else about why they're making the changes they're making.  Many common and easy modifications definitely have their benefits, but those benefits are rarely in the performance sector.     

Go ahead and put fat tires, pods, clubmans, and a cafe seat on your bike if you want.  It won't hurt anybody, and I like the way most of the sohc4's look in that configuration.  Just don't fool yourself into thinking your bike is any faster because of it.

stepping off my soapbox now...
