Pod Filters?
« on: October 22, 2009, 03:06:21 PM »

I like the look of pod filters, but looking at the stock air filter am wondering if they will work as well.  I had an experience years ago replacing a nice big stock air filter with pods, and the bike didn't run as well, especially at high rpms.

Can I (should I) simply replace the stock air filter with pods? 

Looking at that big stock airbox, I can't figure out how to get it out of the frame.  What is the easiest way to do this?

thanks,  Matt

Pods can be tricky to dial in 100%.
They can get wet in the rain and cause difficulty starting.
Wind gust/side winds can bog the engine down sometimes.

The carbs have to be removed to get the air box out.

I switched back to the stock air box after a number of years using pods.
Best move I made.

Also, remember that the hoses between the rear of the carbs and airbox support the carbs.  If you remove them you should add some support or you put strain on the carb holders that can lead to premature failure.  Ed

Learned the hard way last month.  Snapped an intake runner where the mounting bolt is.  Had to pull the whole engine and had my machinist fix it.  Since then I have safety wired the carbs to the valve cover.  This takes a lot of stress off the intake boots.

Should also mention I'm running VM28SC carbs.

You'll find a lot of different opinions on pods.  Some guys love them, some guys really don't.  I'm in the love them crowd.  When you ran pods before did you rejet the carbs?  If not the bike was running way lean and explains why you didn't have good performance (especially on the top end).  If you do run pods, spend the $$$ to go K&N, rejet to get more fuel for the increase in air flow, and as mentioned safety wire the carbs so you don't run into problems down the road.  Personally I've ran through horrible rain and wind and never had issues with my pods that some have experienced, must be my short legs creating a wind break along the outside of the engine cavity!  :D

Yep! Short legs are a plus running pod filters. On one of my bikes I run pods. Took me months to adjust for best performance and it still had problem with wind gusts and a slight flat spot in acceleration. I put on a shroud to cover the top and sides and it runs strong. I do plan to reinstall the airbox this winter. Less hassle more riding.

When I bought my C1 it was missing it's airbox and had been setup for pods (larger jets, 4-1 header), bike had sat for a long time and had 2 ratty pods on the carbs. Upon hearing all the negative things said about pods, I wanted to go back to the stock airbox, but in my case it turned out to be less expensive and less hassle to just buy a new set of  pods than buying an airbox, boots, hoses, and jets, so I bought a set of Unifilters for about $65 and a crankcase vent filter for $3.50, and I do not regret that decision. I had taken the carbs apart and cleaned them so I had to re-adjust the airscrews, which was not a big deal, took a couple days to get them dialed in. Never had to adjust jet needle height or re-jet as they had already been dialed in by the PO. Never had any problems with wind gusts, and I'm 6' tall and have driven the bike through some 30-35 MPH gusts. Throttle response is awesome, definitely screams on the top end. Never ridden the bike in the rain (and don't intend to if I can help it), so I can't say how the rain would affect it.
Edit: Checked the receipt on my Unifilters and they cost $75 after tax, not $65.

I have pods and love them, but I do have a flat spot mid-throttle and do find gusts affect things. The flat spot maybe just an indication that I need to raise the needle a notch, I'm not sure. It doesn't bother me much as I just use more throttle  :D

One great thing about pods is how easy it makes removing the carbs. Only takes a couple of minutes.

I don't mind them riding in the rain, but if I park the bike outside (like when I go to work), I keep an eye on the weather and go put a plastic bag over the pods if it starts to rain.

If you do run pods, spend the $$$ to go K&N,

Anarki +1.

I don't advocate pods of ANY kind because of the problems involved BUT.....if you gotta have them, then spend the bucks as Anarki posted above.
Those low-rent Taiwanese POS's are just a joke. Take a look at what they use for a "filter element" by holding the pod up to the sun or a strong light and then look through from the inside to the outside. What they consider a "filter element" is really a heavy duty industrial paper towel sandwiched between two pieces of wire gauze. It'd be laughable if thousands of guys weren't ruining their motors by using such crap.....
Do yourself a favour and spend the bucks on the K & N's.....or AT LEAST the Uni's.....so you have some REAL filtration. It's your motor longevity we're talking about here..... ;)

I run the stock airbox & filter just got the new boots for the intake side.  I ride a lot in the rain, so the stock airbox helps keep the water out.

I made these velocity stacks mated to two dual throat k&n filters as an alternative to pods. The stacks are made of delrin which I machined at work on the cnc lathe. The filters cost $38 each as opposed to pods which are $42 each and you gotta buy 4.

Now I like that set up! Any chance you'd machine some more stacks? A link to those filters would be nice too.

 You can thank wired George for the awesomeness and cleanliness. As far as the velocity stacks, I made extra sets which I didn't want to jump in and put in a for sale post right away since I am a newbie round these parts, ya know?
  Here's a link for the filters I used:
