I just used the no toil air filter cleaner on my filter on dirtbike. I tried dish washing soap first and it didn't do sht except make the filter the color of the soap (green) Lol. I put the notoil cleaner powder in water and mixed it, Dropped the filter in it. After like 15 seconds it looked brand new.. Now I have to wait on it to dry so I can oil it
Here's the stuff for $20. Notoil air filter kit. It has air filter cleaner, air filter oil, and the rim grease.. Lol
Also here's my old rear wheel bearings. Pretty nasty. Also the wheel bearing seals were so bad they pretty much crumbled to pieces when I pulled them out.
