Not bogging anymore but got popping sounds

[Tang]

my upgrades i did today were the K&N lunchbox air filter and a yoshimura Rs-1 slip on

thing is when i rev it in first gear it bogs then goes up to 2000 rpms and so on but it only bogs on the first gears

i cleaned out my carbs

rejetted it to what Buddah recommends and put the washers in the needles

and i'm idling at 1800 or 1700 just close to 2000rpms

the slip on is not a perfect fit and needs welding tomorrow ( i don't know if this is the cause of boging)

i'd be grateful for any imput on what may cause the bogging

<EDIT i also have two washers in>

[The Buddha]

Float height The float height goes high with use ... on old bikes it can be very very high. Cant have it over 1-2 mm before it will run like crap.
Now 2 washers per needle ... too much, the #4's are very thick ... 1 is pretty enough.
Cool.

Bogging can happen when the slides do not lift fast enough. Plug one of the holes in each of them.

[yamahonkawazuki]

what are teh mix screws at? ie what are tehy turned out to?

[Tang]

ok the mix screws are turned 3 out

1 have 1#4's washers on each needle

float height? so i guess i'll have to research that info

and Dgyver what wholes do i plug?

[spc]

At the base of the slide where the needle sticks through the slide and down into the main jet passageway, on either side of the hole for the needle there are little holes.  Dynojet provides little nylon screws to thread into there, but using an epoxy of some sort would work.

[Tang]

do i have to to this with this setup?

plug the holes?

[spc]

It's worth giving it a try, you don't even have to remove the carbs.  Dgyver might have a better suggestion for how to plug the holes, but I would just figure out what size drill bit will drill them back out to the right size in case you want to undo things and use a dab of epoxy on one hole on each slide.

[dgyver]

I use a 10-24 nylon screw, similar to DJ, but I get a long screw about 1-2" and cut it about 3/8" long. Then use a Dremel to make a slot in the top for a screw driver. Tap the hole in the slide, no drilling required. Install the screw.

Plugging one of the holes has eliminated about 95% of the hesitation for me.

I have not tried plugging the other hole or plugging the hole(s) with a screw that has a hole drilled thru it, making a smaller orifice.

[Tang]

hmm would any of ya'll have pictures of this hole 

[dgyver]

There are 3 holes in the bottom of the slide. The center is for the needle. The other 2 are the holes of topic.

[The Buddha]

Tang ... you block one of the holes and find out its not the problem, I can sell you new slides for $10 a pop.
I have a drawer full of slides with 1 hole plugged as proof that its often unneccesary and usually counterproductive.
Do this test before starting to drill and plug stuff.
Open throttle slowly ... if it runs fine and accelerates fine, then open throttle quick ... if it bogs, then its a case of slides comming up too fast.
Your float needs to be set to the level of the top of the bowl and no higher.
The stock needles you are using, usually do not cause the slide problem to happen ... usually, I have heard of a couple that have.
Try the experiment I told you, if you need a blocked set I'll send you a set to try out. Then either send yours back or pay for them.
Cool.
Buddha.

[Tang]

ok i finally welded my yoshi on and evertyhing i on the first gear taking off i'm giving it thorttle but it won't take off smoothly like its clogged up until around 2000 to 2500 rpms

and slides? what are those :-p

[The Buddha]

No GS runs till you have 3.5+ on the tach ... this is a GS500 not a harley. 2K, dont make me laugh.

BTW you should also check your float level and if air screws or some else is bad, as well as get your carbs synched, valves adjusted, oil changed, intake leak tested and air filter checked and cleaned or replaced ... Oh, new K&N, OK then ... but still do all the rest just to be sure, and its going to be gutless till 3.5 minimum, its a GS.

You check your O rings. All of then nice and soft ?? any cracked or missing ? then swap them out.

Slides - from ~4 - 8 K in higher gears - 5 and 6 ... you whack the throttle open, and it falls on its face, but open throttle slower and it pulls hard is a dead giveaway sign that its comming up too fast.

You got some checking to do, but fret not, 2K is far too low for any GS to run too well ... on ocassion I have gotten the ocassional GS to behave that low down, but I usually dont even bother till the 3K mark.

Cool.
Buddha.

[Tang]

thanks buddah

vavles are adjusted lol but everything else no LMAO lol

anyways i'm going to get a video of me revving it hopefully u can listen to what i mean

[The Buddha]

Yea, get all your maintenance done - wont prolly solve your problem, would just keep the motor from self destructing.
K&N also can kill your low speed response.
And no kidding, I counted today, I have 7 slides that have been screwed up cos the plugs were put in. Yes 7, I believe I broke one ~2 years ago trying to fix it, so I tossed it. I even have a few with 2 plugs in it. I will any dat swap them for a un drilled one ... you want it, just pay mailing. When you're happy, send me either these or yours back, not like they doing much sitting in my garage anyway and the rare bike can need 1 hole blocked.
Cool.

where could i find this kind of screw?

EDIT <here is a video link to my problems http://www.youtube.com/watch?v=h0NdwJxlzEI>

so the screw number is 10-24?

and get it at a size of 1 - 2"?

then cut 3/8'' of it off?

should there be a slot for a screw driver?

and by tapping the hole u mean sticking in the screw?

[dgyver]

I get the screws from Home Depot. The actual length purchased is not important. I buy the longest to get my money's worth, plus I can make several this way.

A slot is required for a flat blade screw driver to install them.

#10-24, #10 is the diameter and 24 is the thread pitch, which is the number of threads per inch. This #10 size fits without having to drill prior to tapping for the threads.

To tap a hole means creating threads in the hole for the screw.
