Topic: Help, Buffo!!! it's my carbs or something!

[jdpas29]

i ran into the same thing when i put pods on my prodject 650...low cruining was fine but as soon as you hit the throttle at any speed above 55 mph she would lag and studder..fact is i was getting to much air per fuel mix even with 125 jets..easy way to adjust this is either go back to stock airbox or in mt case restick the air flow a little..i did this by taking electical tape and taping around the pods about 1/3 the way down then tuning it from there by unwraping and retaping as needed...hope this helps

funny that you mention this...  it was one of the first things i thought about doing when i realized the bike was running lean after putting the pods on.  the only thing was...  how can you gauge the restriction to make sure that one carb isn't getting more/less air than another AND why get pods if you're going to cover them up with tape.  i think i would just go back to the ugly airbox at that point.

i may try it as a last resort...

what i though about earlier this week was why doesn't someone make a pod filter for these bikes with a thicker paper filter that could be a quick switch replacement for the stupid airbox?  i would pay twice the price for filters that had a little bit thicker filter and a choking effect that would resemble at least closely the resistance that the airbox gives.

I give up!

you could get a foam to put in the pods. AS I have not used them, I cannot say if this will work. I will stick with the airbox as it works best in almost all cases.

You can always paint the box to blend better!

So where's Buffo?

[Rastus]

On my K8 the needle jets are not adjustable-no clip settings
i'm running a stock air box with a kerker header and set my fuel mixture screws out three turns and runs great.

I know EXACTLY how you feel.

OMG!!!! FOAM!!!  i can't believe i didn't think of that.  now i just need the right foam so it won't disintegrate if it comes in contact with gas somehow and fly into the carbs...

that will work!   

btw...  i appreciate all the advice, including the advice to revert to the airbox.  my problem with that is that the airbox is 1) ugly 2) impractical to replace as they are all used and probably about as crappy as the one i took off of the bike in the first place whereas many companies are/will be making the pods for a long time 3) the pods look better 4) i don't ride my bike in the rain. 5) the airbox was probably the most poorly engineered thing on the bike.  they warp around the edges and the bolts that hold the thing together are inset in plastic... never a good idea...   -=--- so basically the airbox will never touch my bike again.

[eldar]

WOW aside from a knob cranking on one bolt too much, my airbox is in great shape. I have never seen one warp or anything unless something was done to it. It is actually a very good piece of equipment. It smooths out air flow better than any pod could hope to. I filters better than any pod also and the filters are easier to get than most pod filters. Heck even todays bikes still use a box of some type and not pods. Thats gotta say something.

But if you absolutely need the pods, try to create a shield of some type, others have done that here. Also use UNI foam. The filters should never come in contact with fuel during normal running, at least my box and filter never have.

I think one other reason I likethe box is that pods leave this big open space that looks out of place.

thanks for the help, Eldar. 

i will post a pic of the old lady soon.  i just think it looks sexy with teH podZ!

thats because your bike is a k8

[eldar]

Ignore duster, k8 envy can be an ugly thing!
This happens with ALL 750s!

[dusterdude]

you cant ignore me,im too pretty

[eldar]

Those are some THICK beer goggles!

[dusterdude]

hahahahahaha 

[Buffo]

i n the winter I dont work on mondays or tuesdays...and my computer is at my resturant so...I was not ignoring  you I was riding my bike and resting. 

first I think you have to figure out what you are going to do with your bike...if you do a bunch of carb work and get it running good and then buy a new exhaust you are most likely going to have to re-jet and tune your carbs again. 

Everything you do to the intake and/or exhaust on this bike will affect its jetting needs. these carbs are not hard to work on if you work slow and are organized. I think pods are a mistake. the down sides greatly out ways the up side...it may look cooler but they can make your bike carbs "act" differently in different situations, like rain, exessive dust, high speeds, strong cross winds, not to mention that they need to be cleaned more to keep the jetting right...it is better to have all of your carbs breathing from the same "lung".

750K8 does not have needles with clip positions. Although I have thought about experimenting with them...

if you dont want to spend $300 on a set of pipes you really dont want to pay a mechanic to "do" your carbs...since most of the mechanics have never worked on these bikes you are better off doing it yourself...only the older mechanics put a good amount of time on these.

the only real way to see what your carbs are doing is by doing plug chops...you should do a complete set of plug chops for every item you tweek on your carbs, intake and exhaust...this will tell you if you are going in the right direction.

of course you can only do what your pocketbook allows but if it were me i would: buy and install the new exhaust...what ever one you want but the original will be the easiest to set your  carbs to...then I would buy a stock airbox...i run a K$N factor replacement filter in mine...If you want the pods keep them...get your intake and exhaust to what you want before you start the carbs or you will most likely just have to re-do all the tuning over again.

get used to taking your carbs off...it is not hard to get the cabs off with the airbox...it takes me about 5 minutes and that includes the tank and cables.

someone said to get a tach/dwell meter (if you run points you need one)...buy one

buy a carb sync tool...they are  $50.00 brand new from Dennis Kirk

if you dont attack this correctly, in the right order, you will just end up doing it agian

[Buffo]

someone also said to turn your pilot screws out. that is what I did and it helped a little...mine were turned out so far that turning them out more did nothing...I tapped in bigger low jets...that is the ticket. ours are pressed in you have to tap the hole for bigger ones.

I will be putting bigger mains into my bike as well...It runs great but it is not quite perfect...

Keep in mind that with pods you may never get your ride to funtion properly at all throttle settings and all speeds...you may have to compromise some performance at one setting like low rpm torque to get the bike great at high rpm horse power...maybe...I am not totally sure...I dont run pods for all the trouble they are not worth

[jdpas29]

omg!!!  eldar!!!  THE FOAM!!!  THE LIFE GIVING FOAM!   

it's sooo unbelievably close to running perfectly.  if i give it smoothe pressure on the throttle it runs so smoothe with absolutely no skipping whatsoever.   it idles better and will tun at any speed.  the only problem now is that when i goose it, it sputters...  i believe that the foam i'm using is just too dense and the air can't get in quick enough.  (i used the lawnmower filters... you know... the green ones!  hee hee!!!)  just as an experiment since it's sooo easy to do.)  i'm going to get some unifoam that's a little less dense and thinner tonight from the Zone or O'Reilly's and i bet she will run perfectly!

i feel like i owe you money, Eldar.  do you have paypal?   

[eldar]

No paypal I do however take payment in the form of a dentless front fender!
Hail will beat up a fender bad especially when it is the size of a softball!

[Buffo]

are you replacing the existing foam filters on the pods or just stuffing foam inside the filters?

[jdpas29]

stuffing foam inside!!!  how great and ridiculous is that?!?!?!   

[eldar]

Not too ridiculous if done right. Motorcyclists with our age of bikes must also be inventive.
Without knowing what type of pod you have, I cant say exactly how to put in the foam. But it will help with controlling airflow and filtering, which all pods lack. The suction into the carbs in not that powerful, they are not vacuum cleaners. You can even remove the current filter material from the pods and put the foam in its place.

If you were to ask some of the mods done to these bikes, this would not make it on the top10 list of odd things.

[jime]

the tape idea was just to finish the end of the season i had jetted to lager mains but i think i went too high on them it solved the problem as a temp fix only being we have snow and crap now i'll rejet and fine tune it in.... but it did tell me where the problem was which i was pretty sure to begin with..i am running 125's now will try larger sizes now

[seaweb11]

I believe I  said someting similar 4 pages ago!
"Stock mains are 110, going to 120 is not that big a jump. I tried it and it ran poorly.
I went to  138 mains "

[jdpas29]

nice avatar seaweb!!!   

it's working out pretty well with the foam, except when i goose the throttle it seems to flood or something because i skips horrible and drops power. 

if i give it just a little throttle on up to 1/2 throttle , it's fine and runs like a dream with smoothe acceleration and no jumpiness.  i think that when i goose it, there is just a little too much resistance and it floods.  i'm guessing.  my next plan is to get good exhaust on the old girl.  if that doesn't clear up some of this crap, i'm going to take a piece of rubber tubing and poke it through the foam inside the pod so that when i goose the throttle, it will be able to get a little bit more air.  hopefully that will work.  it's so GHETTO FABULOUS!!!
