restrictors for pods

I got $30 in 8 main jets and $3 in washers for the needles. $100 in jet kits is over priced for pod and/or header jetting. Even if I get pilot jets I?d still have less then $60 in jetting.
4 cheap EMGO pods and cheap Wal-mart cups or whatever just to restrict the airflow down to equal K&N pods would still cause someone to end with $40 to $60 in pods. So restrictors aren?t going to save any real money over good pod filters. Still can use the cups to keep water out of the good pods and catch air for the filter like scoops.

And you still have stock needles, the most critical part of a jet kit.
 
"Carb board beer box". Say that 3 times real fast...
After you drank all the beer.:)

Yes the stock needle can be adjusted to work with pods and/or headers. For cams and big bores I?d change the carbs and ditch the crappy stock carbs. Jet kits are over rated.
 
you can get a front part of the airbox from 750 and just put a single pod on the end of it instead of air cleaner box gives you access to the battery, thats what i did last riding season only used a car cone filter i had to duct tape most of it though.

Have you ever seen the difference between a stock needle and one from a jet kit? completely different animals. A stock needle is the almost the same diameter from one end to the other. Needles from jet kits are tapered. You'll have flat spots with a stock needle.

Yes I?ve seen them. Not all Mikuni BS carb needles are the same and many are tapered. Jet kits are nice but most are not worth the money and a few are.

Thats basically what I did. No dealer around had a filter instock and I wanted to ride so I had a few old K&N's from a banshee I had with outerwears on them. I cut a shop towel in half and wrapped it around the filter and put the outerwears back over it. The bike runs great. I did have it jetted a little on the rich side before I did it though.
 
damn!
a lot of bad information in this thread.
you can not get GS 4cyl. vacuum carbs "correct" through the entire RPM range without a jet kit when the air box is removed.
shim those blunt factory needles till the cows come home...
BS BS BS

Shimming jet needles works most of the time and when it doesn?t just change the needle. You can get Mikuni needles in different sizes and tapers.

Then do what you're gonna do and post back with some (hopefully) positive results. If it means saving someone a buck or two it would be some useful info.

If it dont work out for ya and you end up spending twice the coin on jets and what-not then of course, we wanna know that to;)

I?ll measure the 5d58 stock needles and check my charts. Maybe I could post a lean to rich list of Mikuni needles to replace the 5d58 used in a lot of GS vacuum carbs.

ok i dident want to get into this argument but pondering usually gets me into trouble.

ok starting on the 1000GT and i was surprised with what i had to do. built a new fuse box similar to the one on cliffs site with some mod:D re did a lot of the connections. checked over the usual coils, stator, r/r, signal gen.. ect

it starts with an arm or rags over the airbox side of the carbs for the restriction. im going to do the intake boots & o-rings.

Z1 dosent have the airbox boots for the 1000 i can get them from babbits for about 60$. then i have to seal the airbox itself.

ok heres the real question would it be possible to do POD's with a restriction plate v.s. rejetting or going stock:-k

or one big pod with a custom manifold :eek:

If you got the stock air box and all it needs is boots for $60 dollars WHY would you want to waste the time and money,[effort ] involved in trying to restrict a pod filter that you don't care for the look of in the first place???:eek::eek::eek::eek::eek::eek:
 
It is possible to restrict pods with just a little imagination. On my son's 79 425, he completely customized it out to a military style bike...olive drab paint, custom/welded rack, etc...

He wanted pods so what we did was up his main jets using some from a GS750 we had lying around. We did that because we had bought the pods (Emgos) much earlier and later found out through this forum that they are notorius for allowing too much air. I then found some sheets of camo foam at a Hobby Lobby and took a guess at what might be a workable amount of restriction. I tried about a 60% amount of restriction by cutting a piece of foam and using black zip ties to wrap them around the outside of the pods. And that was it!!! It ran great from the first kick start with very little backfiring. So it can be done....just take your time and use your imagination.
