I'm curious how you are spending $50+ on cleaner and oil for UNI filters, only riding 2-3 times a month........also, how you have torn one. I have used the stock YZ filter and my standby UNI (I rotate between the two) for almost 50 hours of riding and have yet to go through a can of filter oil ($8.95). I use a solution of Simple Green to clean them with in a small bucket (filter in upside down and soak for about 20-30 minutes, all the dirt and bad stuff falls to the bottom of the bucket and leaves the filter slightly oiled still but zero dirt), then oil as necessary. Anyway, I would venture to say that if you are correct in your estimates, there is something you are doing (or not doing) to cause this excessive cost.
Actually, this year I rode quite a bit more than that because I raced a local series and a couple of other races. Not sure I will be riding as much this year but I will ride at least every other weekend. Just guessing on the $50 for cleaning. The biggest thing is I'm just sick of cleaning filters so if the Ready Filters work good I think it would be one less thing to have to spend time on since the wife thinks I spend to much time on the bikes anyway. I have a 3 yr old and 1 yr old so time is an issue. My wife was cool about all the riding I did this year especially since she stays with the kids 24/7. I know I could not do that.
