2 stroke engine without an Air Cleaner

broHSI · #1 07-29-2009, 03:00 PM

Is anyone here running their Chinese 2 stroke engine without an air cleaner?

Maybe you want it to look authentic and just have a venturi stack or a metal screen.
If you are running without an air cleaner how long have you been doing it? and have you had any problems?
Also did you use fenders when you weren't using an air filter?

I don't think it's a good idea, It don't take much to suck something in and hurt your motor.

I don't think running without an air filter sounds like a good idea. Eventually your bound to do damage to your engine. Be on the safe side and get yourself and air filter.

i reccomend everyone use a airfilter,even thou i dont use a air filter all the time.
i have fenders,thats the same as a mud guard.
my engine still runs great(400miles on engine),but now thats its getting warmer outside here,my engine is bogging down at low speeds,but if i thottle it i can still cruise around 25-30mph.
i think i need to adjust something.

cabin just a reminder i am sure but as the weather gets hot the motor does not suck in air as good. So now you nay have a rich condition going on. I would clean or change the plug and do some reads on it to see where it currently is. Also you may have a spark gap issue. Very minor things really.

You could probably rig a foam filter inside a velocity stack, like the hotrodders do.

i think i may have added too much oil in my gas and i may just add some gas to thin it out.

Wheelbender, You mean something like this? And for broHSI, I would never run one of these engines without an airfilter unless you were just wanting to know how long they would last without one.

I love your stack air cleaner. Best one I have ever seen.
Do you have a photo of how the foam is held in? and of the inside?

How much to buy some off you?

Thank you!

I don't run these engines without an air cleaner which is why I am trying to find someone who has done it and to find out what the results were in some detail.
how long did it last?
