Should I get a Donaldson Air Filter

[freshcut]

I have been debating on getting a Donaldson air filter installed on my Huster Super Z 25 Kaw. It currently run's great and I have had no problems with it. I would like to get some opions from people that have had installed to see if it has caused any problems. Should I buy a Donaldson air filter or leave it the way it is. Any feedback much appreciated. Thanks in advance.

Yes, I like mine on my Kohler 25 hp.

I don't feel I have the same power I had before it was put on. But it does stay much cleaner.

Yes....Kawies are very senceitive to dirty air. I have a Donaldson on my super Z and even have to carry a spare filter when doing cleanups. Brace your self, filter elements are around $39.00 each

Excel25 - How much power did you lose? Did the Dondaldson air filter affect cutting in tall grass?

I feel it did some, My dealer and hustler are working on it. It feels like it's not getting enough air. my plugs were wet with gas this morn. when I pulled one.

Mine acts the same way when the filter starts getting dirty. The engin starts running rough like the choke is slightly on. It dosen't take much dirt in the filter to cause this problem either.

Where are you getting your filter from and how much money to install it? If you installed yourself how difficult a job is it? I have the 25hp Kaw as well and am curious after I spent the weekend cleaning dandlions from my current filter.

I do not plan to install it myself because I'm not very mechnically inclined and to my knowledge the carburater will not to be rejetted along with installing the kit. The kit is $149 and the labor rate is about $66 an hour. Since my Hustler already has the knockout for the filter system. I was quoted about 1 hour of labor to rejet the carb and install the filter so I'm looking at around $215 plus tax.

I'm starting to wonder if it's worth doing it considering the issues I'm seeing posted. I'd rather clean the filter more frequently versus losing power and performance?

The kit is available at your Hustler dealer.
You will need to rejet the carburetor.
The kit costs $149.00, and includes everything you need, with very detailed instructions.
If you do not install it yourself, you will need to pay your dealer to install it.
If you are not experienced in carburetor removal and installation on small engines and with rebuilding these carburetors I would pay to have it done.

Hope this helps

I have noticed my speed seems a little slow also. In thick grass I am getting alot of clumping...

I found out today from my dealer that the carbs on the Kawie that get rejetted for the Donaldson air filter are not adjustable. They either work correctly or they don't. I think that is a bummer.

I found that out also this week.......Mines in the shop now!!!

Thanks for the information guys. Sounds like I'll just stick to the normal air filter. Sounds like this just introduces many other problems.

So what's the final answer on this. I am thinking of doing it also, however I won't even consider it if I am going to lose power. When you are talking about these carbs and some working and some not, I am not sure I understand. Is there anyway of knowing if mine will work?

The carburetor on your unit will work with the HD filter kit, the only change to it will be the jets that are removed and replaced with the jets that come with the kit.
In some applications the units are running lean on fuel (not enough) this is due to emmissions regulations set forth by the EPA, and Kawasaki must meet these regulations, this is why the jets are replaced.
I would in most applications still use the HD filter system.
