    after reading several debates about pods. I personally think they look nice, but choose not to run them due to the negatives I have read. My question is has anyone ever made a mod to the side panels or other area to get more air flow? I understand of course more air flow means re jetting, but I thought of this seeing some of the new yamaha's such as the warrior that have the side air "panel" and got me wondering

    hello there i auchely started a post on somthing simular yestertday i cut out a bigger hole to alow more air because my 750 is jetted up and the cam has been reworked for the hole side panel thing would be nice but to my knolage no componey makes one for our bikes but with some plastic weld and the right imagination you coulld make out out of what you all redy have this is what i plan on doing to get more air in further down the road

    was looking at some aftermarket items for the v series yamaha, and then looking at mine, not completely sure how it would work but was thinking of doing a vent intake (forced air style) on the left side opposite the battery case think it may work and replace the left panel with it. but for now just a thought, until I decide on pipes and re jet. would love to see or hear more ideas

    What are the negetives of running pods?

    I have been looking at getting some; however, now I need to find out what negetives you are talking about so that I am not caught completely off gaurd by them...

    From what I understand they are almost impossible to tune in.

    well think most of tuning can be worked out from what i have read here in other posts, just takes patience, but negatives just in my opinion, since I know a couple guys that have never had problems, and some that swear against them is having possible problems with moisture (I do get cought in rain now and then LOL), getting dirty more than a normal filter (just due to exposure to elements), have also heard/read that sometimes inner pods run leaner due to less air flow than outter ones(more fine tunning i guess would solve), placement of a oil breather I've heard can somtimes be a little tough to configure (no biggy realy) and also heard some atmosphere changes (ie. humidity,) effects performance more than normal. Last one may be less important depending on where you live or ride, but here in Minnesota humidity changes often, and ofcourse I would like to just get on and ride rather than tinker with adjustments alot. I have read/heard alot of positives too, and I really like the look of them, but my location and preferences has made me decide to look at alternative mods.

    Why don't you just put in a K&N filter? Don't those let in more air? From what I understand, they don't require any modification either.

    thought about that, but would it do much with the location? wasnt sure it would be that much different

    The thing that bugs me is that my air intake is facing the rear. I figure if I can find a way (such as pods) to increase air flow, the first thing to do would be find a way to get rid of the reversed air intake

    Any other suggestions are always welcome and apprieciated

    I didn't realize you were going for looks too... It sounds to me like you are going to have to fabricate your own intake!

    As far as the intake facing the rear, it doesn't really do that, mine sucks from the top of the air box. So it is really taking in stagnate air from under the seat. This probably HELPS the tuning, because no matter what speed you have, you have the same air pressure at the intake.

    If you had some sort of ram air system, then the carburetors would take in more air as you speed up. This would give you lean conditions at high speeds, and therefore, decreased performance. For that reason alone, I wouldn't do anything that would make you not take in stagnate air.

    Then what is the point of Ram air like they put on some Ninja 750s?

    I believe that the 750 ninja is fuel injected. Which means the onboard computer would sense the engine leaning out and increase the amount of fuel injected into the cylinders. So the ram on the ninja would increase the power available. More air + more fuel = more power. :twisted:

    I just meant it would be a bad thing with our stock carburetors. Maybe you could try it out in a way so that you could go back to original if it didn't work. I actually think it is a cool idea. Maybe the carburetors could compensate in some way for the intake pressure change? Sorry for being a naysayer - if it works, I would do it too!

    i was thinking of doing the same thing agin and the more i though about it i know there is a way to set the stock carbs up for it and the reason i know this is the harley davidsons do it with a hyper-charger (ram-air) and my dad's last HD (fat boy) was carburated and it had the stage 3 screaming eagle with a hyper charger and the shop changed somting in the carbs you would think all you would haf to do is run bigger jets because at idle the carb dosent use the main jet it has a idle jet for that right.


    my under standing of a carb is there are 3 jets idle jet mid range jet and main jet now ovsely the main jet is only used when on the throttel after so far and the idel isent relly used or maby mixes in with the outher 2 but if you just jet up the main jet then put ram air on you would not haf to worry about running lean right i mean with excption maby i dont know a carb as much as a think i know holly carbs have 3 jets for cars never relly understud how theay work though

    But you have to remember that you still idle occasionally at highway speeds! Obviously not much.

    I would expect the most problems in the city. There you can be going 40mph, and idle quite frequently (coming up to stoplights). Also - you are accelerating from stop - and this would use the mid-range jets.

    I guess you could set up your bike for the speed you would be travelling at the most often - but this sounds like a lot of work.

    My personal opinion (take it just like that) - is that you would get a lot more performance out of exhaust and a K&N filter with rejetting. And with no speed dependant problems. With pods - you still would get more air flow on the outer carbs.

    talked to the mechanic agin to day he said the reason that the harleys' can do this is the same way all bike can if custom made.

    he said the only time the butter fly's open up all the way is at full throttel theay are vaccyume controled so the higher the rpm's more vaccume opens the butter fly's more

    the only thing i dident get is you could be going 35mph in 2nd and 35mph and you could be in 5th to so i asked how would that effect it he said that it wouldent matter because in 5th you wouldent be runny as menny rpm's so once agin the butter fly's wouldent open as far.

    so i proceded to ask him how it works at idle he said there are holes in the butter fly's to let a certin ammount of air in for idle so that it wouldent run rich or lean

    so i sat back and tryed to think of more questions and i finely came up with one that i thought for sure would figure this out for once


    at higher speeds (ill said 65mph) the air is forced into the butterfly's at a higher rate than 35mph but im still in 5th gear so wouldent that make it run ritcher or leaner depending on what speed i am going


    his reply was that he dosent know the inner workings but he said ovselly the hyper charger componey work it out

    i had one more question and he said ok one more question


    if i take the hyper charger that theay put on the Hd's and put in on my bike would it run rich or lean his reply was well if you custom mounted the bracket and intake to feed the air to the carb's theortly it would work fine the only thing that might verry is how much vaccume pressure the hd's have compared to our bikes

    so i guess with that in mind if you had the time and know how you could make somting simiular to that or just buy one for the hd's and fab it to your bike




    so my question for any one in here is how do you know if it's running to rich or lean at a certin speed


    wow with all that said know i want to go buy one of thease and tinker around with it but the only problem is i dont know if it's running to rich or lean at certin speed's if any one can answer that i will work on saving to buy one and figure it out and post what to do on the web sight for any one wanting to do it

    i dont currently have one i will pick one up in a couple of week's depending on how much theay cost or if i can find a picture of one tore apart or parts digram ill make one if possible.


    on the up and up i was at lacross fair ground speed way and talked to a guy about old bikes and i asked how theay tuned their cars in the older day's if it had ram air of if theay put a scoop in the hood he said well eather it was just a scoop and ran rich at low rpm's and lean at relly high speeds in excess of 100mph (talking of the good old days)

    he said with butter fly's theay open with only when on full throttel so just to jet up the main jet more than the rest and get it to run rich below 30-35 on full throttel and lean around 90. how i go about doing that i dono but he said as long as it's jetted up to find a way to mount it some where find a road i can goose it up and down the road then come back and check the plugs if it's lean bigger jet if it reads lean smaller jets so i guess that's how ill go about it when i get the money

    You guys have gone way over my head! What is a hypercharger? Is it like a turbo charger?

    so relly it's not forcing all the air in there so that shouldent be to hard to tune because after so fast the rest of the air would be shoved through.

    thanks for the pic's is this of one you bought to put on or just from anouther sight.
