If you fit a pod filter, or take the lid off the air box, you are allowing more air into the engine. Therefore, you must also allow more fuel to mix with the air. To do this, you must increase the jet size in the carburator. I recommend Dyno Jet brand jet kits. They will have all the parts necessary as well as tuning guidelines to follow.

SOURCE: Air Filter Pods

Check the K&NFilters Website and you'll probably find the right size for your bike. Be aware, though, that changing air filters can lead to less performance as a result of carburetor jetting problems that can take some time to solve, and get your bike running well gain. Usually the manufacturer's set-up works better than home-fiddled-with ones.

SOURCE: whats better overall pod filters or stock airbox

this is a topic of much debate. I have never found a great deal of advantage in performance on dynos when fitting a pod style filter as apposed to the stock panel filters. If you are after more induction noise ("****") then a pod filter is the go. If you are not so worried about induction noise, stick with the panel filter as they usually have a pretty larger surface area and are easier to clean and find replacements for.

SOURCE: changed from standard air box air cleaner to pod

Going to the manufactures specs or anybody's specs for that matter won't help you, you have interrupted the air flow, Get an adj jet from Dyna flow, I did the same thing, went back to the oem specs and still wouldn't run. Got a Dyna flow kit and off it went. Those things are expensive but worth it. Plus they are adj. And you get a free dyno check if you ever find somebody with a dyno tester. My Mikunis were a little newer, but I'm sure they got something. I found mine on Ebay. Hope this helps.

After 2 days outdoor parking of my Kawasaki KLE Anhelo 250cc in cold and snow weather bike doesn't works normally.All works related done:cylinder inspected valve grinded,spark plugs replaced,carburett


Sounds as though you have a blocked airbox intake. Look where the air is drawn into the box for obstructions. It is also possible that you are running your carbs too rich and the extra air that is being drawn in without the cover being fitted is putting the fuel/air mix right.

Pw 50, cleaned air filter,put new plug in,bike starts fine,then feels like choke is on and bogs down,plug is wet ,smells of petrol,,,,no power , tried running to clear through ,sputters then sounds...


cover up the drilled holes this can cause problems, why was a new carb fitted? did the shop have it running?
not likely rings .
check carb for flooding and correct jet sizes.
check safety kill\start\run switch for shorts.

The Bike was running fine then I removed the air box to install a set of pod air filters and now the bike wont run, are the carbs needing to be adjusted to compensate for not having the original air box?


my goodness kids do your research. carbs mix air and gas very specifically. any change in air intake will mean you also need to adjust the flow of gas in carbs. even if you use an aftermarket filter in the original air box it will still change the amount of air going to the carb, it might not be as drastic as a pod filter but it is still a change. you will probably need to change the main jets in your carburetor as well as play with the air/fuel mixture setting screw.

Hyper charger...


The design of the bike is what makes this difficult. Your airbox is located under your seat and feeds the carburetors via the backbone of the bike. The air passage is basically in the middle of the fuel tank and connected to the carburetors in the center of the V of the engine, which are a downdraft design. Unless you can create a new intake tract from the side of the bike to the carburetors, you cannot mount a hypercharger on this model.
All of the models I am familiar with mounting a hypercharger on already have their airbox located on the side of the motor, so it is not a big deal to change.

Air box


Because the K&N filters are much less restrictive than the original airbox and filter, the bike may run lean, and you MAY have to have the carb jets reworked/changed.
