Not available...just orderd new jets. just check tracking will be here thursday...went with 127.5s...Two questions for you tho maybe you can answer....ONE where can i find a new baffle for my VH? Idiot PO cut it...and TWO..wheres the best place to get GOOD pods? These Emgos are old and crappy, and i want good ones...

It's the jet needle that is the important component in the DJ kit. Maybe you can buy just that, or go with the DJ kit for the 1000.
I think you can get the baffle from somewhere like denniskirk.com Or maybe call V&H directly and see if they will sell you one. As for the pods.... shop around. I bought mine from denniskirk, but I have since seen them cheaper on ebay. Go with the K&N's. And if you do get K&N's, don't bother setting up your carbs until you get them.... if you dial in your carbs now for the emgos, you'll be dialing them in again for the K&N's because they move more air than the emgos.

My needle is adjustable via the clip...VMs not CVs..and an oddball VM26 on top of that...didnt have spacers, needle sits directly in the slide and fits inside of the slide arm...thought i was missing parts when i first cracked them open...but after some research alas i am ok. Thanks for the info..surfing now, and already sent VH an email...much obliged.

My stock needle was adjustable, too, and so is the needle in the DJ kit. It's the taper on the DJ needle that is different and seems to make the difference when going with pods and pipe. Many have tried to dial in their stock carbs using the stock parts and have ended up pulling their hair out. I'm not saying it can't be done, but there will probably be alot of trial and error. The best help you will get will be with the advise from KeithKrause. He's the VM GOD.

Already there...lol he advised me on the bigger jets, and to move my clip on the stock needle to 4 from the top instead of the stock possition. Ive found an intake leak on my number one boot, and the jets and rings are on their way...we'll find out soon enough i guess...You have VMs on that 1000?? i didnt pay attn...if so what size/model K&N did you order? Nevermind...found em...lol

Yes, stock VM26's with the DJ kit and K&N's... #2454 I think? Can't remember. But they are the same for all the VM's for the 750, 850, and 1000

Just for reference, my stock needles were adjustable on my 82 GS1100E. It is a Canadian model and we got adjustable needles up to about 83 or so. If you are looking to get adjustable needles and don't want the Dynojet ones (some swear at the sharper taper of the DJ needles on the CV carbs), order needles from a Canadian Suzuki dealer and you should get the good ones...
I had no issues dialing in my 1100 with a Kerker 4-1 and Emgo pods. It took a few tries, as it usually does, but it wasn't a fight. This winter I am going to try making my own megaphone tail pipe/muffler to fit the Kerker header and will be installing APE pods as an upgrade to the Emgo's, so I will be doing the carb tuning dance next spring again.

yeah i was just about to ask, looking at your photobucket stuff...what did you use to clean that thing?? It looks AWESOME...

Thanks, Mark!
Simple Green and lots of toothbrushes and baby bottle brushes. Scrub, scrub, and scrub some more. And then scrub some more......
I've since used the Purple Power stuff and it works good, too.

dude608,
Sorry if I highjacked your thread a bit...
What bike do you have?
When going to pods you usually always need to re-jet. The easiest way is to buy a Dynojet kit if it is available for your model. If a kit is not available, ask for help here on the GSR. Someone will help you get it dialed in. Will you also be running an aftermarket exhaust or the stock one? That will also make a difference as the aftermarket exhausts (most of them) will add some extra flow as well.

Getting back to the original question, I would be amazed if you could replace the stock airbox with pods and not need to rejet. These bikes (actually, pretty much any carbureted bike from the late 70's on) are all jetted quite lean for emissions purposes. Especially on the pilot and lower needle cicuits, where the EPA testing is performed. So, it already is borderline lean in the stock configuration. Then you put pods on and increase flow by a major amount... That demands the jetting be corrected or it just will not work properly. Unfortunately, there is just no way around that. As Bruce said, start with a DJ kit if you can and ask questions on these forums. Carb tuning is not black magic, it just requires a little bit of knowledge, time and a methodical approach. Especially a methodical approach.

Hi,
Ms. SqDancerLynn1 pointed out motorcyclecarbs.com in another thread and this particular page is full of "rule of thumb" jetting guidelines that may come in handy as a reference for us novice carb mechanics.
Thank you for your indulgence,

In a couple days, I'll give an update on how the DJ jet kit affected my GS1150 with pods & a 4-1 pipe. When I got into the carbs, the PO hadn't make ANY changes and it bogged badly on acceleration ~
JM
EDIT: That's pretty accurate BassCliff, I went from 132.5 to 138 per Dynojet's reccomendations on the main jet. That guide may help me fiddling ~

The jetting guideline is pretty decent for getting the mains correct. Unfortunately, that is the easiest and least sensitive part. Getting the pilot and needle circuits right is much harder and requires more fiddling. You don't even need main jets in place to tune the pilot and lower needle circuits, you can just leave the main jets out until you are sure you have the pilot stuff sorted. At least you can on the BS carbs, I am not sure of the VM ones as I've never tinkered with them.
Since this thread is about carbs and it seems there are a lot of novice carb tuners looking in, this is the correct tuning sequence (for BS carbs, that is):
1. Pilot first. Get it sorted with the air screws until it idles and runs ok at small throttle openings. If you get to more than 3 turns out or less than 1 turn out, you need to change your pilot jet to the next size up or down, as the case may be.
2. Needle. Once you have your pilot set, start trying part throttle settings and see how it runs on the needle at part throttle settings. This area can be hard to diagnose rich/lean and often you have to try the next needle setting to see if it got better or worse before you know which way is correct. If in doubt, go richer first because a rich condition won't damage your engine like lean can.
3. Main jet. Once you are running good from idle to bigger throttle openings, then you can start sorting the main jet and doing plug chops to get it right. Remember, that slightly rich is OK and will not affect how your bike runs while being safer in spring/fall and on those hot days in summer when you just have to let her breathe a bit.
Remember, it is throttle position, not rpm or road speed that determines which circuit you are running on. The pilot controls from idle to around 1/4 throttle, the needle controls 1/4 to around 5/8-3/4 and main is WOT. These might be slightly off, it's been a while since I worked on this. Keep these in mind when road testing, it helps a lot to put a piece of tape on your bar and your grip with markings for full, half, 1/4 etc. to let you see how much throttle you are holding while testing. The reason you start at the bottom and work your way up is that the lower circuits affect the higher ones, but not the other way around.
Mark
You can gain a bit of leeway on your pilot jets by adjusting the fuel meter screw - it's a bitch to do though as you burn your hands using the world's shortest, thinnest screwdriver right up against a hot cylinder. And you need to be real careful as well, as the end of those screws are very, very fragile and can easily snap and get stuck in (no need to ask me how I know that and the broken tips are a grade one bugger to get out). As you are doing 2 variables on the same line now you have to match each carb as closely as possible on the airscrews to get a good balance at tickover.
A colourtune makes the whole thing a lot easier and is now an essential part of my kit.
The slide cutaway also has an important effect at around 1/4 throttle - if you like it takes over first once the pilot circuit has finished its job. I've messed around DIYing these a few times to get the 'perfect' set up but I don't bother anymore as it's not easy and you need to be prepared to bin ruined slides if you're as cack handed as me. In practice, you can get it close enough so as not to notice.
Absolutely sound advice already about different pods but you can't over-emphasise; different makes will need different set ups.
And my view on Dynojet - there's no need to run to that expense (and aren't they bloody expensive for what they are?) as with VMs you've got plenty of adjustable elements anyway. In my book, if Dynojet are as hot as they claim they should be selling the reshaped slides as well.
