Fell Apart Like a Dead Grasshopper

Yup, my air filter fell apart like a dead grasshopper when I was cleaning it this AM.

Is the UNI filter more durable than than the OEM filter?

wow, the only time I've seen that has been when using No-Toil cleaner and hot water (Twin Air filters)......which is why I use solvent/gasoline only now. No issues with stock or Uni with solvent/gas.

For some reason it seems that stale gasahol seems to soften the glue on some filters. Then too hot of water in the soapy bath tends to finish it off!

I've got a KLX140 OEM foam filter in my shop right now with this problem, last month it was a KX450.
For some reason no after-market company has made a replacement for the KLX140 oem filter yet.
Uni-Filter application chart shows they supposedly do. But the UNI filter also supposedly fits 77-78 IT & YZ 250's & 400's and the pics don't appear compatible.

I use Maxima Air Filter Cleaner and have been for years with no problems.

Perhaps I had my hot water rinse too hot.

I had the same issue with a YZ250 filter and KLR filters. I was using No-Toil to oil them after cleaning and also storing a spare in a ziploc bag with oil. I think what was happening is that the No-Toil was getting old (I wasn't riding as much). Now I buy a small spray can of filter oil so it gets used up more quickly and so far my filter has been holding up.

I'm using PJ1 Foam Filter Oil Treatment Spray, which has worked well in the past. I purchased a UNI filter and will see if it holds up better than the OEM filter.

From reading the above I think the high tech filter cleaning systems are the culprit. I have about 100,000 miles on my oldest 2008 and I think it still has the original filter in it. I just squeeze them in some gasoline, squeeze it out and let them dry a few minutes and go ride.

I did have the glue on about an inch of one seam come loose at a motel in Mexico. I went to an office supply store and bought some rubber cement and fixed it. It never came loose.

Get some rubber cement and put that one back together just to see if it works for you.

Thanks for the rubber cement idea there GoMotor. But I've already replaced the "dead" filter with a Uni.

How about using Kerosene to clean the filter? Would it be too harsh? I just eyeballed my filter a couple weeks ago and it's doing fine thus far but I know I'll probably need to clean it before I put the bike away for winter.

A bad attitude is like a flat tire, you can't go anywhere until you change it.
